3 | CHANGES WITH 209: |
4 | ||
5 | * A new component "systemd-networkd" has been added that can | |
6 | be used to configure local network interfaces statically or | |
8b7d0494 JSJ |
7 | via DHCP. It is capable of bringing up bridges, VLANs, and |
8 | bonding. Currently, no hook-ups for interactive network | |
4670e9d5 | 9 | configuration are provided. Use this for your initrd, |
8b7d0494 JSJ |
10 | container, embedded, or server setup if you need a simple, |
11 | yet powerful, network configuration solution. This | |
4670e9d5 | 12 | configuration subsystem is quite nifty, as it allows wildcard |
1e190502 | 13 | hotplug matching in interfaces. For example, with a single |
4670e9d5 | 14 | configuration snippet, you can configure that all Ethernet |
1e190502 ZJS |
15 | interfaces showing up are automatically added to a bridge, |
16 | or similar. It supports link-sensing and more. | |
e49b5aad LP |
17 | |
18 | * A new tool "systemd-socket-proxyd" has been added which can | |
4c2413bf | 19 | act as a bidirectional proxy for TCP sockets. This is |
e49b5aad LP |
20 | useful for adding socket activation support to services that |
21 | do not actually support socket activation, including virtual | |
4c2413bf | 22 | machines and the like. |
e49b5aad LP |
23 | |
24 | * Add a new tool to save/restore rfkill state on | |
25 | shutdown/boot. | |
26 | ||
8b7d0494 JSJ |
27 | * Save/restore state of keyboard backlights in addition to |
28 | display backlights on shutdown/boot. | |
e49b5aad LP |
29 | |
30 | * udev learned a new SECLABEL{} construct to label device | |
31 | nodes with a specific security label when they appear. For | |
4c2413bf | 32 | now, only SECLABEL{selinux} is supported, but the syntax is |
e49b5aad LP |
33 | prepared for additional security frameworks. |
34 | ||
35 | * udev gained a new scheme to configure link-level attributes | |
36 | from files in /etc/systemd/network/*.link. These files can | |
8b7d0494 | 37 | match against MAC address, device path, driver name and type, |
4c2413bf | 38 | and will apply attributes like the naming policy, link speed, |
8b7d0494 | 39 | MTU, duplex settings, Wake-on-LAN settings, MAC address, MAC |
e49b5aad LP |
40 | address assignment policy (randomized, ...). |
41 | ||
dfb08b05 ZJS |
42 | * The configuration of network interface naming rules for |
43 | "permanent interface names" has changed: a new NamePolicy= | |
44 | setting in the [Link] section of .link files determines the | |
45 | priority of possible naming schemes (onboard, slot, mac, | |
46 | path). The default value of this setting is determined by | |
47 | /usr/lib/net/links/99-default.link. Old | |
48 | 80-net-name-slot.rules udev configuration file has been | |
49 | removed, so local configuration overriding this file should | |
50 | be adapated to override 99-default.link instead. | |
51 | ||
e49b5aad | 52 | * When the User= switch is used in a unit file, also |
4c2413bf | 53 | initialize $SHELL= based on the user database entry. |
e49b5aad LP |
54 | |
55 | * systemd no longer depends on libdbus. All communication is | |
56 | now done with sd-bus, systemd's low-level bus library | |
57 | implementation. | |
58 | ||
59 | * kdbus support has been added to PID 1 itself. When kdbus is | |
4c2413bf | 60 | enabled, this causes PID 1 to set up the system bus and |
e49b5aad LP |
61 | enable support for a new ".busname" unit type that |
62 | encapsulates bus name activation on kdbus. It works a little | |
63 | bit like ".socket" units, except for bus names. A new | |
64 | generator has been added that converts classic dbus1 service | |
65 | activation files automatically into native systemd .busname | |
66 | and .service units. | |
67 | ||
68 | * sd-bus: add a light-weight vtable implementation that allows | |
69 | defining objects on the bus with a simple static const | |
70 | vtable array of its methods, signals and properties. | |
71 | ||
8b7d0494 | 72 | * systemd will not generate or install static dbus |
e49b5aad | 73 | introspection data anymore to /usr/share/dbus-1/interfaces, |
1e190502 | 74 | as the precise format of these files is unclear, and |
e49b5aad LP |
75 | nothing makes use of it. |
76 | ||
77 | * A proxy daemon is now provided to proxy clients connecting | |
78 | via classic D-Bus AF_UNIX sockets to kdbus, to provide full | |
79 | compatibility with classic D-Bus. | |
80 | ||
81 | * A bus driver implementation has been added that supports the | |
82 | classic D-Bus bus driver calls on kdbus, also for | |
83 | compatibility purposes. | |
84 | ||
85 | * A new API "sd-event.h" has been added that implements a | |
86 | minimal event loop API built around epoll. It provides a | |
87 | couple of features that direct epoll usage is lacking: | |
b9761003 | 88 | prioritization of events, scales to large numbers of timer |
e49b5aad LP |
89 | events, per-event timer slack (accuracy), system-wide |
90 | coalescing of timer events, exit handlers, watchdog | |
91 | supervision support using systemd's sd_notify() API, child | |
92 | process handling. | |
93 | ||
94 | * A new API "sd-rntl.h" has been added that provides an API | |
95 | around the route netlink interface of the kernel, similar in | |
96 | style to "sd-bus.h". | |
97 | ||
7e95eda5 PF |
98 | * A new API "sd-dhcp-client.h" has been added that provides a |
99 | small DHCPv4 client-side implementation. This is used by | |
e49b5aad LP |
100 | "systemd-networkd". |
101 | ||
4c2413bf | 102 | * There is a new kernel command line option |
8b7d0494 JSJ |
103 | "systemd.restore_state=0|1". When set to "0", none of the |
104 | systemd tools will restore saved runtime state to hardware | |
105 | devices. More specifically, the rfkill and backlight states | |
106 | are not restored. | |
e49b5aad LP |
107 | |
108 | * The FsckPassNo= compatibility option in mount/service units | |
109 | has been removed. The fstab generator will now add the | |
110 | necessary dependencies automatically, and does not require | |
111 | PID1's support for that anymore. | |
112 | ||
8b7d0494 | 113 | * journalctl gained a new switch, --list-boots, that lists |
e49b5aad LP |
114 | recent boots with their times and boot IDs. |
115 | ||
116 | * The various tools like systemctl, loginctl, timedatectl, | |
117 | busctl, systemd-run, ... have gained a new switch "-M" to | |
118 | connect to a specific, local OS container (as direct | |
119 | connection, without requiring SSH). This works on any | |
120 | container that is registered with machined, such as those | |
121 | created by libvirt-lxc or nspawn. | |
122 | ||
123 | * systemd-run and systemd-analyze also gained support for "-H" | |
4c2413bf | 124 | to connect to remote hosts via SSH. This is particularly |
8b7d0494 JSJ |
125 | useful for systemd-run because it enables queuing of jobs |
126 | onto remote systems. | |
e49b5aad LP |
127 | |
128 | * machinectl gained a new command "login" to open a getty | |
129 | login in any local container. This works with any container | |
130 | that is registered with machined (such as those created by | |
8e420494 | 131 | libvirt-lxc or nspawn), and which runs systemd inside. |
e49b5aad LP |
132 | |
133 | * machinectl gained a new "reboot" command that may be used to | |
134 | trigger a reboot on a specific container that is registered | |
135 | with machined. This works on any container that runs an init | |
136 | system of some kind. | |
137 | ||
138 | * systemctl gained a new "list-timers" command to print a nice | |
139 | listing of installed timer units with the times they elapse | |
140 | next. | |
141 | ||
142 | * Alternative reboot() parameters may now be specified on the | |
143 | "systemctl reboot" command line and are passed to the | |
144 | reboot() system call. | |
145 | ||
146 | * systemctl gained a new --job-mode= switch to configure the | |
147 | mode to queue a job with. This is a more generic version of | |
8b7d0494 | 148 | --fail, --irreversible, and --ignore-dependencies, which are |
e49b5aad LP |
149 | still available but not advertised anymore. |
150 | ||
e49b5aad LP |
151 | * /etc/systemd/system.conf gained new settings to configure |
152 | various default timeouts of units, as well as the default | |
b9761003 | 153 | start limit interval and burst. These may still be overridden |
e49b5aad LP |
154 | within each Unit. |
155 | ||
270f1624 LP |
156 | * PID1 will now export on the bus profile data of the security |
157 | policy upload process (such as the SELinux policy upload to | |
8e420494 | 158 | the kernel). |
e49b5aad | 159 | |
4670e9d5 | 160 | * journald: when forwarding logs to the console, include |
1e190502 ZJS |
161 | timestamps (following the setting in |
162 | /sys/module/printk/parameters/time). | |
e49b5aad LP |
163 | |
164 | * OnCalendar= in timer units now understands the special | |
165 | strings "yearly" and "annually". (Both are equivalent) | |
166 | ||
167 | * The accuracy of timer units is now configurable with the new | |
168 | AccuracySec= setting. It defaults to 1min. | |
169 | ||
170 | * A new dependency type JoinsNamespaceOf= has been added that | |
171 | allows running two services within the same /tmp and network | |
172 | namespace, if PrivateNetwork= or PrivateTmp= are used. | |
173 | ||
174 | * A new command "cat" has been added to systemctl. It outputs | |
175 | the original unit file of a unit, and concatenates the | |
1e190502 ZJS |
176 | contents of additional "drop-in" unit file snippets, so that |
177 | the full configuration is shown. | |
e49b5aad LP |
178 | |
179 | * systemctl now supports globbing on the various "list-xyz" | |
180 | commands, like "list-units" or "list-sockets", as well as on | |
1e190502 ZJS |
181 | those commands which take multiple unit names. |
182 | ||
183 | * journalctl's --unit= switch gained support for globbing. | |
e49b5aad LP |
184 | |
185 | * All systemd daemons now make use of the watchdog logic so | |
186 | that systemd automatically notices when they hang. | |
187 | ||
4c2413bf | 188 | * If the $container_ttys environment variable is set, |
e49b5aad LP |
189 | getty-generator will automatically spawn a getty for each |
190 | listed tty. This is useful for container managers to request | |
191 | login gettys to be spawned on as many ttys as needed. | |
192 | ||
193 | * %h, %s, %U specifier support is not available anymore when | |
194 | used in unit files for PID 1. This is because NSS calls are | |
195 | not safe from PID 1. They stay available for --user | |
196 | instances of systemd, and as special case for the root user. | |
197 | ||
e49b5aad LP |
198 | * loginctl gained a new "--no-legend" switch to turn off output |
199 | of the legend text. | |
200 | ||
201 | * The "sd-login.h" API gained three new calls: | |
202 | sd_session_is_remote(), sd_session_get_remote_user(), | |
203 | sd_session_get_remote_host() to query information about | |
204 | remote sessions. | |
205 | ||
8e420494 LP |
206 | * The udev hardware database now also carries vendor/product |
207 | information of SDIO devices. | |
e49b5aad LP |
208 | |
209 | * The "sd-daemon.h" API gained a new sd_watchdog_enabled() to | |
210 | determine whether watchdog notifications are requested by | |
211 | the system manager. | |
212 | ||
1e190502 | 213 | * Socket-activated per-connection services now include a |
e49b5aad LP |
214 | short description of the connection parameters in the |
215 | description. | |
216 | ||
4c2413bf | 217 | * tmpfiles gained a new "--boot" option. When this is not used, |
e49b5aad | 218 | only lines where the command character is not suffixed with |
4670e9d5 | 219 | "!" are executed. When this option is specified, those |
1e190502 ZJS |
220 | options are executed too. This partitions tmpfiles |
221 | directives into those that can be safely executed at any | |
222 | time, and those which should be run only at boot (for | |
223 | example, a line that creates /run/nologin). | |
e49b5aad | 224 | |
c0c5af00 | 225 | * A new API "sd-resolve.h" has been added which provides a simple |
4c2413bf | 226 | asynchronous wrapper around glibc NSS host name resolution |
e49b5aad | 227 | calls, such as getaddrinfo(). In contrast to glibc's |
4c2413bf JE |
228 | getaddrinfo_a(), it does not use signals. In contrast to most |
229 | other asynchronous name resolution libraries, this one does | |
230 | not reimplement DNS, but reuses NSS, so that alternate | |
e49b5aad | 231 | host name resolution systems continue to work, such as mDNS, |
8b7d0494 | 232 | LDAP, etc. This API is based on libasyncns, but it has been |
e49b5aad LP |
233 | cleaned up for inclusion in systemd. |
234 | ||
6300b3ec LP |
235 | * The APIs "sd-journal.h", "sd-login.h", "sd-id128.h", |
236 | "sd-daemon.h" are no longer found in individual libraries | |
237 | libsystemd-journal.so, libsystemd-login.so, | |
238 | libsystemd-id128.so, libsystemd-daemon.so. Instead, we have | |
8b7d0494 JSJ |
239 | merged them into a single library, libsystemd.so, which |
240 | provides all symbols. The reason for this is cyclic | |
e49b5aad | 241 | dependencies, as these libraries tend to use each other's |
6300b3ec LP |
242 | symbols. So far, we've managed to workaround that by linking |
243 | a copy of a good part of our code into each of these | |
244 | libraries again and again, which, however, makes certain | |
245 | things hard to do, like sharing static variables. Also, it | |
246 | substantially increases footprint. With this change, there | |
247 | is only one library for the basic APIs systemd | |
248 | provides. Also, "sd-bus.h", "sd-memfd.h", "sd-event.h", | |
249 | "sd-rtnl.h", "sd-resolve.h", "sd-utf8.h" are found in this | |
250 | library as well, however are subject to the --enable-kdbus | |
251 | switch (see below). Note that "sd-dhcp-client.h" is not part | |
252 | of this library (this is because it only consumes, never | |
253 | provides, services of/to other APIs). To make the transition | |
8b7d0494 | 254 | easy from the separate libraries to the unified one, we |
4c2413bf | 255 | provide the --enable-compat-libs compile-time switch which |
e49b5aad LP |
256 | will generate stub libraries that are compatible with the |
257 | old ones but redirect all calls to the new one. | |
258 | ||
8b7d0494 | 259 | * All of the kdbus logic and the new APIs "sd-bus.h", |
e49b5aad | 260 | "sd-memfd.h", "sd-event.h", "sd-rtnl.h", "sd-resolve.h", |
8b7d0494 JSJ |
261 | and "sd-utf8.h" are compile-time optional via the |
262 | "--enable-kdbus" switch, and they are not compiled in by | |
263 | default. To make use of kdbus, you have to explicitly enable | |
4c2413bf | 264 | the switch. Note however, that neither the kernel nor the |
e49b5aad LP |
265 | userspace API for all of this is considered stable yet. We |
266 | want to maintain the freedom to still change the APIs for | |
4c2413bf | 267 | now. By specifying this build-time switch, you acknowledge |
e49b5aad | 268 | that you are aware of the instability of the current |
ad42cf73 KS |
269 | APIs. |
270 | ||
271 | * Also, note that while kdbus is pretty much complete, | |
e49b5aad | 272 | it lacks one thing: proper policy support. This means you |
8b7d0494 | 273 | can build a fully working system with all features; however, |
4c2413bf JE |
274 | it will be highly insecure. Policy support will be added in |
275 | one of the next releases, at the same time that we will | |
276 | declare the APIs stable. | |
e49b5aad | 277 | |
8b7d0494 | 278 | * When the kernel command-line argument "kdbus" is specified, |
ad42cf73 | 279 | systemd will automatically load the kdbus.ko kernel module. At |
8b7d0494 | 280 | this stage of development, it is only useful for testing kdbus |
ad42cf73 | 281 | and should not be used in production. Note: if "--enable-kdbus" |
8b7d0494 | 282 | is specified, and the kdbus.ko kernel module is available, and |
ad42cf73 KS |
283 | "kdbus" is added to the kernel command line, the entire system |
284 | runs with kdbus instead of dbus-daemon, with the above mentioned | |
285 | problem of missing the system policy enforcement. Also a future | |
286 | version of kdbus.ko or a newer systemd will not be compatible with | |
287 | each other, and will unlikely be able to boot the machine if only | |
288 | one of them is updated. | |
289 | ||
e49b5aad | 290 | * systemctl gained a new "import-environment" command which |
4c2413bf | 291 | uploads the caller's environment (or parts thereof) into the |
e49b5aad LP |
292 | service manager so that it is inherited by services started |
293 | by the manager. This is useful to upload variables like | |
294 | $DISPLAY into the user service manager. | |
295 | ||
296 | * A new PrivateDevices= switch has been added to service units | |
297 | which allows running a service with a namespaced /dev | |
298 | directory that does not contain any device nodes for | |
4c2413bf | 299 | physical devices. More specifically, it only includes devices |
8b7d0494 | 300 | such as /dev/null, /dev/urandom, and /dev/zero which are API |
e49b5aad LP |
301 | entry points. |
302 | ||
303 | * logind has been extended to support behaviour like VT | |
304 | switching on seats that do not support a VT. This makes | |
305 | multi-session available on seats that are not the first seat | |
306 | (seat0), and on systems where kernel support for VTs has | |
8b7d0494 | 307 | been disabled at compile-time. |
e49b5aad LP |
308 | |
309 | * If a process holds a delay lock for system sleep or shutdown | |
1e190502 | 310 | and fails to release it in time, we will now log its |
e49b5aad LP |
311 | identity. This makes it easier to identify processes that |
312 | cause slow suspends or power-offs. | |
313 | ||
1e190502 ZJS |
314 | * When parsing /etc/crypttab, support for a new key-slot= |
315 | option as supported by Debian is added. It allows indicating | |
316 | which LUKS slot to use on disk, speeding up key loading. | |
e49b5aad | 317 | |
1e190502 ZJS |
318 | * The sd_journald_sendv() API call has been checked and |
319 | officially declared to be async-signal-safe so that it may | |
320 | be invoked from signal handlers for logging purposes. | |
e49b5aad LP |
321 | |
322 | * Boot-time status output is now enabled automatically after a | |
323 | short timeout if boot does not progress, in order to give | |
8e420494 | 324 | the user an indication what she or he is waiting for. |
1e190502 ZJS |
325 | |
326 | * The boot-time output has been improved to show how much time | |
327 | remains until jobs expire. | |
e49b5aad LP |
328 | |
329 | * The KillMode= switch in service units gained a new possible | |
8b7d0494 | 330 | value "mixed". If set, and the unit is shut down, then the |
e49b5aad | 331 | initial SIGTERM signal is sent only to the main daemon |
8e420494 | 332 | process, while the following SIGKILL signal is sent to |
e49b5aad LP |
333 | all remaining processes of the service. |
334 | ||
4c2413bf JE |
335 | * When a scope unit is registered, a new property "Controller" |
336 | may be set. If set to a valid bus name, systemd will send a | |
e49b5aad LP |
337 | RequestStop() signal to this name when it would like to shut |
338 | down the scope. This may be used to hook manager logic into | |
339 | the shutdown logic of scope units. Also, scope units may now | |
8b7d0494 | 340 | be put in a special "abandoned" state, in which case the |
e49b5aad LP |
341 | manager process which created them takes no further |
342 | responsibilities for it. | |
343 | ||
1e190502 | 344 | * When reading unit files, systemd will now verify |
e49b5aad LP |
345 | the access mode of these files, and warn about certain |
346 | suspicious combinations. This has been added to make it | |
347 | easier to track down packaging bugs where unit files are | |
348 | marked executable or world-writable. | |
349 | ||
350 | * systemd-nspawn gained a new "--setenv=" switch to set | |
8b7d0494 | 351 | container-wide environment variables. The similar option in |
1e190502 ZJS |
352 | systemd-activate was renamed from "--environment=" to |
353 | "--setenv=" for consistency. | |
e49b5aad LP |
354 | |
355 | * systemd-nspawn has been updated to create a new kdbus domain | |
356 | for each container that is invoked, thus allowing each | |
b9761003 | 357 | container to have its own set of system and user buses, |
8b7d0494 | 358 | independent of the host. |
e49b5aad LP |
359 | |
360 | * systemd-nspawn gained a new --drop-capability= switch to run | |
361 | the container with less capabilities than the default. Both | |
b9761003 | 362 | --drop-capability= and --capability= now take the special |
e49b5aad LP |
363 | string "all" for dropping or keeping all capabilities. |
364 | ||
365 | * systemd-nspawn gained new switches for executing containers | |
366 | with specific SELinux labels set. | |
367 | ||
368 | * systemd-nspawn gained a new --quiet switch to not generate | |
369 | any additional output but the container's own console | |
370 | output. | |
371 | ||
372 | * systemd-nspawn gained a new --share-system switch to run a | |
373 | container without PID namespacing enabled. | |
374 | ||
375 | * systemd-nspawn gained a new --register= switch to control | |
1e190502 | 376 | whether the container is registered with systemd-machined or |
8e420494 | 377 | not. This is useful for containers that do not run full |
e49b5aad LP |
378 | OS images, but only specific apps. |
379 | ||
380 | * systemd-nspawn gained a new --keep-unit which may be used | |
8b7d0494 | 381 | when invoked as the only program from a service unit, and |
e49b5aad | 382 | results in registration of the unit service itself in |
1e190502 | 383 | systemd-machined, instead of a newly opened scope unit. |
e49b5aad LP |
384 | |
385 | * systemd-nspawn gained a new --network-interface= switch for | |
386 | moving arbitrary interfaces to the container. The new | |
4c2413bf | 387 | --network-veth switch creates a virtual Ethernet connection |
8b7d0494 JSJ |
388 | between host and container. The new --network-bridge= |
389 | switch then allows assigning the host side of this virtual | |
390 | Ethernet connection to a bridge device. | |
e49b5aad | 391 | |
6afc95b7 LP |
392 | * systemd-nspawn gained a new --personality= switch for |
393 | setting the kernel personality for the container. This is | |
ca721e36 LP |
394 | useful when running a 32bit container on a 64bit host. A |
395 | similar option Personality= is now also available in service | |
396 | units. | |
6afc95b7 | 397 | |
e49b5aad LP |
398 | * logind will now also track a "Desktop" identifier for each |
399 | session which encodes the desktop environment of it. This is | |
400 | useful for desktop environments that want to identify | |
401 | multiple running sessions of itself easily. | |
402 | ||
403 | * A new SELinuxContext= setting for service units has been | |
404 | added that allows setting a specific SELinux execution | |
405 | context for a service. | |
406 | ||
407 | * Most systemd client tools will now honour $SYSTEMD_LESS for | |
408 | settings of the "less" pager. By default, these tools will | |
8b7d0494 JSJ |
409 | override $LESS to allow certain operations to work, such as |
410 | jump-to-the-end. With $SYSTEMD_LESS, it is possible to | |
e49b5aad LP |
411 | influence this logic. |
412 | ||
413 | * systemd's "seccomp" hook-up has been changed to make use of | |
414 | the libseccomp library instead of using its own | |
415 | implementation. This has benefits for portability among | |
416 | other things. | |
417 | ||
4c2413bf | 418 | * For usage together with SystemCallFilter=, a new |
8b7d0494 | 419 | SystemCallErrorNumber= setting has been introduced that |
8e420494 | 420 | allows configuration of a system error number to return on |
8b7d0494 | 421 | filtered system calls, instead of immediately killing the |
e49b5aad LP |
422 | process. Also, SystemCallArchitectures= has been added to |
423 | limit access to system calls of a particular architecture | |
424 | (in order to turn off support for unused secondary | |
4c2413bf | 425 | architectures). There is also a global |
8b7d0494 | 426 | SystemCallArchitectures= setting in system.conf now to turn |
e49b5aad LP |
427 | off support for non-native system calls system-wide. |
428 | ||
210054d7 KS |
429 | * systemd requires a kernel with a working name_to_handle_at(), |
430 | please see the kernel config requirements in the README file. | |

459 | CHANGES WITH 208: |
460 | ||
461 | * logind has gained support for facilitating privileged input | |
462 | and drm device access for unprivileged clients. This work is | |
463 | useful to allow Wayland display servers (and similar | |
464 | programs, such as kmscon) to run under the user's ID and | |
465 | access input and drm devices which are normally | |
466 | protected. When this is used (and the kernel is new enough) | |
467 | logind will "mute" IO on the file descriptors passed to | |
468 | Wayland as long as it is in the background and "unmute" it | |
469 | if it returns into the foreground. This allows secure | |
470 | session switching without allowing background sessions to | |
471 | eavesdrop on input and display data. This also introduces | |
472 | session switching support if VT support is turned off in the | |
473 | kernel, and on seats that are not seat0. | |
474 | ||
475 | * A new kernel command line option luks.options= is understood | |
476 | now which allows specifiying LUKS options for usage for LUKS | |
477 | encrypted partitions specified with luks.uuid=. | |
478 | ||
479 | * tmpfiles.d(5) snippets may now use specifier expansion in | |
480 | path names. More specifically %m, %b, %H, %v, are now | |
481 | replaced by the local machine id, boot id, hostname, and | |
482 | kernel version number. | |
483 | ||
484 | * A new tmpfiles.d(5) command "m" has been introduced which | |
485 | may be used to change the owner/group/access mode of a file | |
486 | or directory if it exists, but do nothing if it doesn't. | |
487 | ||
488 | * This release removes high-level support for the | |
489 | MemorySoftLimit= cgroup setting. The underlying kernel | |
490 | cgroup attribute memory.soft_limit= is currently badly | |
491 | designed and likely to be removed from the kernel API in its | |
492 | current form, hence we shouldn't expose it for now. | |
493 | ||
494 | * The memory.use_hierarchy cgroup attribute is now enabled for | |
495 | all cgroups systemd creates in the memory cgroup | |
496 | hierarchy. This option is likely to be come the built-in | |
497 | default in the kernel anyway, and the non-hierarchial mode | |
498 | never made much sense in the intrinsically hierarchial | |
499 | cgroup system. | |
500 | ||
501 | * A new field _SYSTEMD_SLICE= is logged along with all journal | |
502 | messages containing the slice a message was generated | |
503 | from. This is useful to allow easy per-customer filtering of | |
504 | logs among other things. | |
505 | ||
506 | * systemd-journald will no longer adjust the group of journal | |
507 | files it creates to the "systemd-journal" group. Instead we | |
508 | rely on the journal directory to be owned by the | |
509 | "systemd-journal" group, and its setgid bit set, so that the | |
510 | kernel file system layer will automatically enforce that | |
511 | journal files inherit this group assignment. The reason for | |
512 | this change is that we cannot allow NSS look-ups from | |
513 | journald which would be necessary to resolve | |
514 | "systemd-journal" to a numeric GID, because this might | |
515 | create deadlocks if NSS involves synchronous queries to | |
516 | other daemons (such as nscd, or sssd) which in turn are | |
517 | logging clients of journald and might block on it, which | |
518 | would then dead lock. A tmpfiles.d(5) snippet included in | |
519 | systemd will make sure the setgid bit and group are | |
520 | properly set on the journal directory if it exists on every | |
521 | boot. However, we recommend adjusting it manually after | |
522 | upgrades too (or from RPM scriptlets), so that the change is | |
523 | not delayed until next reboot. | |
524 | ||
525 | * Backlight and random seed files in /var/lib/ have moved into | |
526 | the /var/lib/systemd/ directory, in order to centralize all | |
527 | systemd generated files in one directory. | |
528 | ||
529 | * Boot time performance measurements (as displayed by | |
530 | "systemd-analyze" for example) will now read ACPI 5.0 FPDT | |
531 | performance information if that's available to determine how | |
532 | much time BIOS and boot loader initialization required. With | |
533 | a sufficiently new BIOS you hence no longer need to boot | |
534 | with Gummiboot to get access to such information. | |

4f0be680 LP |
546 | CHANGES WITH 207: |
547 | ||
548 | * The Restart= option for services now understands a new | |
f3a165b0 | 549 | on-watchdog setting, which will restart the service |
4f0be680 LP |
550 | automatically if the service stops sending out watchdog keep |
551 | alive messages (as configured with WatchdogSec=). | |
552 | ||
553 | * The getty generator (which is responsible for bringing up a | |
554 | getty on configured serial consoles) will no longer only | |
555 | start a getty on the primary kernel console but on all | |
556 | others, too. This makes the order in which console= is | |
557 | specified on the kernel command line less important. | |
558 | ||
559 | * libsystemd-logind gained a new sd_session_get_vt() call to | |
560 | retrieve the VT number of a session. | |
561 | ||
562 | * If the option "tries=0" is set for an entry of /etc/crypttab | |
563 | its passphrase is queried indefinitely instead of any | |
564 | maximum number of tries. | |
565 | ||
566 | * If a service with a configure PID file terminates its PID | |
567 | file will now be removed automatically if it still exists | |
568 | afterwards. This should put an end to stale PID files. | |
569 | ||
570 | * systemd-run will now also take relative binary path names | |
571 | for execution and no longer insists on absolute paths. | |
572 | ||
573 | * InaccessibleDirectories= and ReadOnlyDirectories= now take | |
574 | paths that are optionally prefixed with "-" to indicate that | |
575 | it should not be considered a failure if they don't exist. | |
576 | ||
f3a165b0 KS |
577 | * journalctl -o (and similar commands) now understands a new |
578 | output mode "short-precise", it is similar to "short" but | |
4f0be680 LP |
579 | shows timestamps with usec accuracy. |
580 | ||
581 | * The option "discard" (as known from Debian) is now | |
582 | synonymous to "allow-discards" in /etc/crypttab. In fact, | |
387abf80 | 583 | "discard" is preferred now (since it is easier to remember |
4f0be680 LP |
584 | and type). |
585 | ||
f3a165b0 | 586 | * Some licensing clean-ups were made, so that more code is now |
4f0be680 LP |
587 | LGPL-2.1 licensed than before. |
588 | ||
589 | * A minimal tool to save/restore the display backlight | |
590 | brightness across reboots has been added. It will store the | |
f3a165b0 | 591 | backlight setting as late as possible at shutdown, and |
4f0be680 LP |
592 | restore it as early as possible during reboot. |
593 | ||
594 | * A logic to automatically discover and enable home and swap | |
595 | partitions on GPT disks has been added. With this in place | |
596 | /etc/fstab becomes optional for many setups as systemd can | |
597 | discover certain partitions located on the root disk | |
598 | automatically. Home partitions are recognized under their | |
599 | GPT type ID 933ac7e12eb44f13b8440e14e2aef915. Swap | |
600 | partitions are recognized under their GPT type ID | |
601 | 0657fd6da4ab43c484e50933c84b4f4f. | |
602 | ||
603 | * systemd will no longer pass any environment from the kernel | |
604 | or initrd to system services. If you want to set an | |
605 | environment for all services, do so via the kernel command | |
606 | line systemd.setenv= assignment. | |
607 | ||
387abf80 LP |
608 | * The systemd-sysctl tool no longer natively reads the file |
609 | /etc/sysctl.conf. If desired, the file should be symlinked | |
610 | from /etc/sysctl.d/99-sysctl.conf. Apart from providing | |
611 | legacy support by a symlink rather than built-in code, it | |
612 | also makes the otherwise hidden order of application of the | |
613 | different files visible. (Note that this partly reverts to a | |
614 | pre-198 application order of sysctl knobs!) | |
04bf3c1a | 615 | |
4f0be680 LP |
616 | * The "systemctl set-log-level" and "systemctl dump" commands |
617 | have been moved to systemd-analyze. | |
618 | ||
619 | * systemd-run learned the new --remain-after-exit switch, | |
620 | which causes the scope unit not to be cleaned up | |
621 | automatically after the process terminated. | |
622 | ||
623 | * tmpfiles learned a new --exclude-prefix= switch to exclude | |
624 | certain paths from operation. | |
625 | ||
626 | * journald will now automatically flush all messages to disk | |
627 | as soon as a message of the log priorities CRIT, ALERT or | |
628 | EMERG is received. | |

408f281b LP |
646 | CHANGES WITH 206: |
647 | ||
648 | * The documentation has been updated to cover the various new | |
649 | concepts introduced with 205. | |
650 | ||
651 | * Unit files now understand the new %v specifier which | |
652 | resolves to the kernel version string as returned by "uname | |
653 | -r". | |
654 | ||
655 | * systemctl now supports filtering the unit list output by | |
656 | load state, active state and sub state, using the new | |
33b521be | 657 | --state= parameter. |
408f281b LP |
658 | |
659 | * "systemctl status" will now show the results of the | |
660 | condition checks (like ConditionPathExists= and similar) of | |
661 | the last start attempts of the unit. They are also logged to | |
662 | the journal. | |
663 | ||
664 | * "journalctl -b" may now be used to look for boot output of a | |
665 | specific boot. Try "journalctl -b -1" for the previous boot, | |
666 | but the syntax is substantially more powerful. | |
667 | ||
668 | * "journalctl --show-cursor" has been added which prints the | |
669 | cursor string the last shown log line. This may then be used | |
670 | with the new "journalctl --after-cursor=" switch to continue | |
671 | browsing logs from that point on. | |
672 | ||
673 | * "journalctl --force" may now be used to force regeneration | |
674 | of an FSS key. | |
675 | ||
251cc819 LP |
676 | * Creation of "dead" device nodes has been moved from udev |
677 | into kmod and tmpfiles. Previously, udev would read the kmod | |
678 | databases to pre-generate dead device nodes based on meta | |
679 | information contained in kernel modules, so that these would | |
680 | be auto-loaded on access rather then at boot. As this | |
681 | doesn't really have much to do with the exposing actual | |
682 | kernel devices to userspace this has always been slightly | |
683 | alien in the udev codebase. Following the new scheme kmod | |
684 | will now generate a runtime snippet for tmpfiles from the | |
685 | module meta information and it now is tmpfiles' job to the | |
686 | create the nodes. This also allows overriding access and | |
687 | other parameters for the nodes using the usual tmpfiles | |
688 | facilities. As side effect this allows us to remove the | |
689 | CAP_SYS_MKNOD capability bit from udevd entirely. | |
690 | ||
691 | * logind's device ACLs may now be applied to these "dead" | |
692 | devices nodes too, thus finally allowing managed access to | |
693 | devices such as /dev/snd/sequencer whithout loading the | |
694 | backing module right-away. | |
408f281b LP |
695 | |
696 | * A new RPM macro has been added that may be used to apply | |
697 | tmpfiles configuration during package installation. | |
698 | ||
699 | * systemd-detect-virt and ConditionVirtualization= now can | |
700 | detect User-Mode-Linux machines (UML). | |
701 | ||
251cc819 LP |
702 | * journald will now implicitly log the effective capabilities |
703 | set of processes in the message metadata. | |
408f281b LP |
704 | |
705 | * systemd-cryptsetup has gained support for TrueCrypt volumes. | |
706 | ||
707 | * The initrd interface has been simplified (more specifically, | |
708 | support for passing performance data via environment | |
709 | variables and fsck results via files in /run has been | |
710 | removed). These features were non-essential, and are | |
711 | nowadays available in a much nicer way by having systemd in | |
712 | the initrd serialize its state and have the hosts systemd | |
713 | deserialize it again. | |
714 | ||
28f5c779 KS |
715 | * The udev "keymap" data files and tools to apply keyboard |
716 | specific mappings of scan to key codes, and force-release | |
717 | scan code lists have been entirely replaced by a udev | |
718 | "keyboard" builtin and a hwdb data file. | |
408f281b | 719 | |
251cc819 LP |
720 | * systemd will now honour the kernel's "quiet" command line |
721 | argument also during late shutdown, resulting in a | |
722 | completely silent shutdown when used. | |
723 | ||
724 | * There's now an option to control the SO_REUSEPORT socket | |
725 | option in .socket units. | |
726 | ||
727 | * Instance units will now automatically get a per-template | |
728 | subslice of system.slice unless something else is explicitly | |
729 | configured. For example, instances of sshd@.service will now | |
730 | implicitly be placed in system-sshd.slice rather than | |
731 | system.slice as before. | |
732 | ||
733 | * Test coverage support may now be enabled at build time. | |

744 | ||
00aa832b LP |
745 | CHANGES WITH 205: |
746 | ||
747 | * Two new unit types have been introduced: | |
748 | ||
749 | Scope units are very similar to service units, however, are | |
750 | created out of pre-existing processes -- instead of PID 1 | |
751 | forking off the processes. By using scope units it is | |
752 | possible for system services and applications to group their | |
753 | own child processes (worker processes) in a powerful way | |
754 | which then maybe used to organize them, or kill them | |
755 | together, or apply resource limits on them. | |
756 | ||
757 | Slice units may be used to partition system resources in an | |
758 | hierarchial fashion and then assign other units to them. By | |
759 | default there are now three slices: system.slice (for all | |
760 | system services), user.slice (for all user sessions), | |
761 | machine.slice (for VMs and containers). | |
762 | ||
763 | Slices and scopes have been introduced primarily in | |
764 | context of the work to move cgroup handling to a | |
765 | single-writer scheme, where only PID 1 | |
766 | creates/removes/manages cgroups. | |
767 | ||
768 | * There's a new concept of "transient" units. In contrast to | |
769 | normal units these units are created via an API at runtime, | |
770 | not from configuration from disk. More specifically this | |
771 | means it is now possible to run arbitrary programs as | |
772 | independent services, with all execution parameters passed | |
773 | in via bus APIs rather than read from disk. Transient units | |
774 | make systemd substantially more dynamic then it ever was, | |
775 | and useful as a general batch manager. | |
776 | ||
777 | * logind has been updated to make use of scope and slice units | |
778 | for managing user sessions. As a user logs in he will get | |
779 | his own private slice unit, to which all sessions are added | |
780 | as scope units. We also added support for automatically | |
781 | adding an instance of user@.service for the user into the | |
782 | slice. Effectively logind will no longer create cgroup | |
783 | hierarchies on its own now, it will defer entirely to PID 1 | |
784 | for this by means of scope, service and slice units. Since | |
785 | user sessions this way become entities managed by PID 1 | |
786 | the output of "systemctl" is now a lot more comprehensive. | |
787 | ||
788 | * A new mini-daemon "systemd-machined" has been added which | |
789 | may be used by virtualization managers to register local | |
790 | VMs/containers. nspawn has been updated accordingly, and | |
791 | libvirt will be updated shortly. machined will collect a bit | |
792 | of meta information about the VMs/containers, and assign | |
793 | them their own scope unit (see above). The collected | |
794 | meta-data is then made available via the "machinectl" tool, | |
795 | and exposed in "ps" and similar tools. machined/machinectl | |
796 | is compile-time optional. | |
797 | ||
798 | * As discussed earlier, the low-level cgroup configuration | |
799 | options ControlGroup=, ControlGroupModify=, | |
800 | ControlGroupPersistent=, ControlGroupAttribute= have been | |
801 | removed. Please use high-level attribute settings instead as | |
802 | well as slice units. | |
803 | ||
804 | * A new bus call SetUnitProperties() has been added to alter | |
805 | various runtime parameters of a unit. This is primarily | |
806 | useful to alter cgroup parameters dynamically in a nice way, | |
807 | but will be extended later on to make more properties | |
808 | modifiable at runtime. systemctl gained a new set-properties | |
809 | command that wraps this call. | |
810 | ||
811 | * A new tool "systemd-run" has been added which can be used to | |
812 | run arbitrary command lines as transient services or scopes, | |
813 | while configuring a number of settings via the command | |
814 | line. This tool is currently very basic, however already | |
815 | very useful. We plan to extend this tool to even allow | |
816 | queuing of execution jobs with time triggers from the | |
817 | command line, similar in fashion to "at". | |
818 | ||
819 | * nspawn will now inform the user explicitly that kernels with | |
820 | audit enabled break containers, and suggest the user to turn | |
821 | off audit. | |
822 | ||
823 | * Support for detecting the IMA and AppArmor security | |
824 | frameworks with ConditionSecurity= has been added. | |
825 | ||
826 | * journalctl gained a new "-k" switch for showing only kernel | |
1fda0ab5 ZJS |
827 | messages, mimicking dmesg output; in addition to "--user" |
828 | and "--system" switches for showing only user's own logs | |
829 | and system logs. | |
00aa832b LP |
830 | |
831 | * systemd-delta can now show information about drop-in | |
832 | snippets extending unit files. | |
833 | ||
834 | * libsystemd-bus has been substantially updated but is still | |
835 | not available as public API. | |
836 | ||
837 | * systemd will now look for the "debug" argument on the kernel | |
838 | command line and enable debug logging, similar to | |
839 | "systemd.log_level=debug" already did before. | |
840 | ||
841 | * "systemctl set-default", "systemctl get-default" has been | |
842 | added to configure the default.target symlink, which | |
843 | controls what to boot into by default. | |
844 | ||
1fda0ab5 ZJS |
845 | * "systemctl set-log-level" has been added as a convenient |
846 | way to raise and lower systemd logging threshold. | |
847 | ||
00aa832b LP |
848 | * "systemd-analyze plot" will now show the time the various |
849 | generators needed for execution, as well as information | |
850 | about the unit file loading. | |
851 | ||
00aa832b LP |
852 | * libsystemd-journal gained a new sd_journal_open_files() call |
853 | for opening specific journal files. journactl also gained a | |
854 | new switch to expose this new functionality. Previously we | |
855 | only supported opening all files from a directory, or all | |
856 | files from the system, as opening individual files only is | |
857 | racy due to journal file rotation. | |
858 | ||
859 | * systemd gained the new DefaultEnvironment= setting in | |
860 | /etc/systemd/system.conf to set environment variables for | |
861 | all services. | |
862 | ||
863 | * If a privileged process logs a journal message with the | |
864 | OBJECT_PID= field set, then journald will automatically | |
865 | augment this with additional OBJECT_UID=, OBJECT_GID=, | |
866 | OBJECT_COMM=, OBJECT_EXE=, ... fields. This is useful if | |
867 | system services want to log events about specific client | |
868 | processes. journactl/systemctl has been updated to make use | |
869 | of this information if all log messages regarding a specific | |
870 | unit is requested. | |

886 | CHANGES WITH 204: |
887 | ||
888 | * The Python bindings gained some minimal support for the APIs | |
889 | exposed by libsystemd-logind. | |
890 | ||
891 | * ConditionSecurity= gained support for detecting SMACK. Since | |
892 | this condition already supports SELinux and AppArmor we only | |
893 | miss IMA for this. Patches welcome! | |

898 | CHANGES WITH 203: |
899 | ||
900 | * systemd-nspawn will now create /etc/resolv.conf if | |
901 | necessary, before bind-mounting the host's file onto it. | |
902 | ||
903 | * systemd-nspawn will now store meta information about a | |
904 | container on the container's cgroup as extended attribute | |
905 | fields, including the root directory. | |
906 | ||
907 | * The cgroup hierarchy has been reworked in many ways. All | |
908 | objects any of the components systemd creates in the cgroup | |
b82eed9a | 909 | tree are now suffixed. More specifically, user sessions are |
2f3fcf85 LP |
910 | now placed in cgroups suffixed with ".session", users in |
911 | cgroups suffixed with ".user", and nspawn containers in | |
912 | cgroups suffixed with ".nspawn". Furthermore, all cgroup | |
913 | names are now escaped in a simple scheme to avoid collision | |
914 | of userspace object names with kernel filenames. This work | |
915 | is preparation for making these objects relocatable in the | |
916 | cgroup tree, in order to allow easy resource partitioning of | |
917 | these objects without causing naming conflicts. | |
918 | ||
919 | * systemctl list-dependencies gained the new switches | |
920 | --plain, --reverse, --after and --before. | |
921 | ||
922 | * systemd-inhibit now shows the process name of processes that | |
923 | have taken an inhibitor lock. | |
924 | ||
925 | * nss-myhostname will now also resolve "localhost" | |
926 | implicitly. This makes /etc/hosts an optional file and | |
927 | nicely handles that on IPv6 ::1 maps to both "localhost" and | |
928 | the local hostname. | |
929 | ||
930 | * libsystemd-logind.so gained a new call | |
931 | sd_get_machine_names() to enumerate running containers and | |
932 | VMs (currently only supported by very new libvirt and | |
933 | nspawn). sd_login_monitor can now be used to watch | |
934 | VMs/containers coming and going. | |
935 | ||
936 | * .include is not allowed recursively anymore, and only in | |
937 | unit files. Usually it is better to use drop-in snippets in | |
938 | .d/*.conf anyway, as introduced with systemd 198. | |
939 | ||
940 | * systemd-analyze gained a new "critical-chain" command that | |
941 | determines the slowest chain of units run during system | |
942 | boot-up. It is very useful for tracking down where | |
943 | optimizing boot time is the most beneficial. | |
944 | ||
945 | * systemd will no longer allow manipulating service paths in | |
946 | the name=systemd:/system cgroup tree using ControlGroup= in | |
947 | units. (But is still fine with it in all other dirs.) | |
948 | ||
949 | * There's a new systemd-nspawn@.service service file that may | |
950 | be used to easily run nspawn containers as system | |
951 | services. With the container's root directory in | |
952 | /var/lib/container/foobar it is now sufficient to run | |
953 | "systemctl start systemd-nspawn@foobar.service" to boot it. | |
954 | ||
955 | * systemd-cgls gained a new parameter "--machine" to list only | |
956 | the processes within a certain container. | |
957 | ||
958 | * ConditionSecurity= now can check for "apparmor". We still | |
959 | are lacking checks for SMACK and IMA for this condition | |
960 | check though. Patches welcome! | |
961 | ||
962 | * A new configuration file /etc/systemd/sleep.conf has been | |
963 | added that may be used to configure which kernel operation | |
964 | systemd is supposed to execute when "suspend", "hibernate" | |
965 | or "hybrid-sleep" is requested. This makes the new kernel | |
966 | "freeze" state accessible to the user. | |
967 | ||
968 | * ENV{SYSTEMD_WANTS} in udev rules will now implicitly escape | |
969 | the passed argument if applicable. | |

ef3b5246 LP |
980 | CHANGES WITH 202: |
981 | ||
982 | * The output of 'systemctl list-jobs' got some polishing. The | |
983 | '--type=' argument may now be passed more than once. A new | |
984 | command 'systemctl list-sockets' has been added which shows | |
985 | a list of kernel sockets systemd is listening on with the | |
986 | socket units they belong to, plus the units these socket | |
987 | units activate. | |
988 | ||
989 | * The experimental libsystemd-bus library got substantial | |
990 | updates to work in conjunction with the (also experimental) | |
991 | kdbus kernel project. It works well enough to exchange | |
992 | messages with some sophistication. Note that kdbus is not | |
993 | ready yet, and the library is mostly an elaborate test case | |
994 | for now, and not installable. | |
995 | ||
996 | * systemd gained a new unit 'systemd-static-nodes.service' | |
997 | that generates static device nodes earlier during boot, and | |
998 | can run in conjunction with udev. | |
999 | ||
1000 | * libsystemd-login gained a new call sd_pid_get_user_unit() | |
1001 | to retrieve the user systemd unit a process is running | |
1002 | in. This is useful for systems where systemd is used as | |
1003 | session manager. | |
1004 | ||
1005 | * systemd-nspawn now places all containers in the new /machine | |
1006 | top-level cgroup directory in the name=systemd | |
1007 | hierarchy. libvirt will soon do the same, so that we get a | |
1008 | uniform separation of /system, /user and /machine for system | |
1009 | services, user processes and containers/virtual | |
1010 | machines. This new cgroup hierarchy is also useful to stick | |
1011 | stable names to specific container instances, which can be | |
7c04ad2d | 1012 | recognized later this way (this name may be controlled |
ef3b5246 LP |
1013 | via systemd-nspawn's new -M switch). libsystemd-login also |
1014 | gained a new call sd_pid_get_machine_name() to retrieve the | |
1015 | name of the container/VM a specific process belongs to. | |
1016 | ||
1017 | * bootchart can now store its data in the journal. | |
1018 | ||
1019 | * libsystemd-journal gained a new call | |
1020 | sd_journal_add_conjunction() for AND expressions to the | |
1021 | matching logic. This can be used to express more complex | |
1022 | logical expressions. | |
1023 | ||
1024 | * journactl can now take multiple --unit= and --user-unit= | |
1025 | switches. | |
1026 | ||
1027 | * The cryptsetup logic now understands the "luks.key=" kernel | |
1028 | command line switch for specifying a file to read the | |
7c04ad2d | 1029 | decryption key from. Also, if a configured key file is not |
ef3b5246 LP |
1030 | found the tool will now automatically fall back to prompting |
1031 | the user. | |
1032 | ||
cbeabcfb ZJS |
1033 | * Python systemd.journal module was updated to wrap recently |
1034 | added functions from libsystemd-journal. The interface was | |
1035 | changed to bring the low level interface in s.j._Reader | |
1036 | closer to the C API, and the high level interface in | |
1037 | s.j.Reader was updated to wrap and convert all data about | |
1038 | an entry. | |

d3a86981 LP |
1047 | CHANGES WITH 201: |
1048 | ||
1049 | * journalctl --update-catalog now understands a new --root= | |
1050 | option to operate on catalogs found in a different root | |
1051 | directory. | |
1052 | ||
1053 | * During shutdown after systemd has terminated all running | |
1054 | services a final killing loop kills all remaining left-over | |
1055 | processes. We will now print the name of these processes | |
1056 | when we send SIGKILL to them, since this usually indicates a | |
1057 | problem. | |
1058 | ||
1059 | * If /etc/crypttab refers to password files stored on | |
1060 | configured mount points automatic dependencies will now be | |
1061 | generated to ensure the specific mount is established first | |
1062 | before the key file is attempted to be read. | |
1063 | ||
1064 | * 'systemctl status' will now show information about the | |
1065 | network sockets a socket unit is listening on. | |
1066 | ||
1067 | * 'systemctl status' will also shown information about any | |
1068 | drop-in configuration file for units. (Drop-In configuration | |
1069 | files in this context are files such as | |
1070 | /etc/systemd/systemd/foobar.service.d/*.conf) | |
1071 | ||
1072 | * systemd-cgtop now optionally shows summed up CPU times of | |
1073 | cgroups. Press '%' while running cgtop to switch between | |
1074 | percentage and absolute mode. This is useful to determine | |
1075 | which cgroups use up the most CPU time over the entire | |
1076 | runtime of the system. systemd-cgtop has also been updated | |
1077 | to be 'pipeable' for processing with further shell tools. | |
1078 | ||
1079 | * 'hostnamectl set-hostname' will now allow setting of FQDN | |
1080 | hostnames. | |
1081 | ||
1082 | * The formatting and parsing of time span values has been | |
1083 | changed. The parser now understands fractional expressions | |
1084 | such as "5.5h". The formatter will now output fractional | |
1085 | expressions for all time spans under 1min, i.e. "5.123456s" | |
1086 | rather than "5s 123ms 456us". For time spans under 1s | |
1087 | millisecond values are shown, for those under 1ms | |
1088 | microsecond values are shown. This should greatly improve | |
1089 | all time-related output of systemd. | |
1090 | ||
1091 | * libsystemd-login and libsystemd-journal gained new | |
1092 | functions for querying the poll() events mask and poll() | |
1093 | timeout value for integration into arbitrary event | |
1094 | loops. | |
1095 | ||
1096 | * localectl gained the ability to list available X11 keymaps | |
1097 | (models, layouts, variants, options). | |
1098 | ||
1099 | * 'systemd-analyze dot' gained the ability to filter for | |
1100 | specific units via shell-style globs, to create smaller, | |
1101 | more useful graphs. I.e. it's now possible to create simple | |
1102 | graphs of all the dependencies between only target units, or | |
1103 | of all units that Avahi has dependencies with. | |

1113 | CHANGES WITH 200: |
1114 | ||
1115 | * The boot-time readahead implementation for rotating media | |
1116 | will now read the read-ahead data in multiple passes which | |
1117 | consist of all read requests made in equidistant time | |
1118 | intervals. This means instead of strictly reading read-ahead | |
1119 | data in its physical order on disk we now try to find a | |
1120 | middle ground between physical and access time order. | |
1121 | ||
1122 | * /etc/os-release files gained a new BUILD_ID= field for usage | |
1123 | on operating systems that provide continuous builds of OS | |
1124 | images. | |

35911459 LP |
1130 | CHANGES WITH 199: |
1131 | ||
1132 | * systemd-python gained an API exposing libsystemd-daemon. | |
1133 | ||
1134 | * The SMACK setup logic gained support for uploading CIPSO | |
1135 | security policy. | |
1136 | ||
1137 | * Behaviour of PrivateTmp=, ReadWriteDirectories=, | |
1138 | ReadOnlyDirectories= and InaccessibleDirectories= has | |
1139 | changed. The private /tmp and /var/tmp directories are now | |
1140 | shared by all processes of a service (which means | |
1141 | ExecStartPre= may now leave data in /tmp that ExecStart= of | |
1142 | the same service can still access). When a service is | |
1143 | stopped its temporary directories are immediately deleted | |
a87197f5 | 1144 | (normal clean-up with tmpfiles is still done in addition to |
35911459 LP |
1145 | this though). |
1146 | ||
1147 | * By default, systemd will now set a couple of sysctl | |
1148 | variables in the kernel: the safe sysrq options are turned | |
1149 | on, IP route verification is turned on, and source routing | |
1150 | disabled. The recently added hardlink and softlink | |
1151 | protection of the kernel is turned on. These settings should | |
1152 | be reasonably safe, and good defaults for all new systems. | |
1153 | ||
1154 | * The predictable network naming logic may now be turned off | |
a87197f5 | 1155 | with a new kernel command line switch: net.ifnames=0. |
35911459 LP |
1156 | |
1157 | * A new libsystemd-bus module has been added that implements a | |
1158 | pretty complete D-Bus client library. For details see: | |
1159 | ||
1160 | http://lists.freedesktop.org/archives/systemd-devel/2013-March/009797.html | |
1161 | ||
c20d8298 | 1162 | * journald will now explicitly flush the journal files to disk |
a87197f5 ZJS |
1163 | at the latest 5min after each write. The file will then also |
1164 | be marked offline until the next write. This should increase | |
1165 | reliability in case of a crash. The synchronization delay | |
1166 | can be configured via SyncIntervalSec= in journald.conf. | |
35911459 LP |
1167 | |
1168 | * There's a new remote-fs-setup.target unit that can be used | |
1169 | to pull in specific services when at least one remote file | |
1170 | system is to be mounted. | |
1171 | ||
1172 | * There are new targets timers.target and paths.target as | |
1173 | canonical targets to pull user timer and path units in | |
1174 | from. This complements sockets.target with a similar | |
1175 | purpose for socket units. | |
1176 | ||
6a7d3d68 LP |
1177 | * libudev gained a new call udev_device_set_attribute_value() |
1178 | to set sysfs attributes of a device. | |
1179 | ||
a87197f5 ZJS |
1180 | * The udev daemon now sets the default number of worker |
1181 | processes executed in parallel based on the number of available | |
c20d8298 | 1182 | CPUs instead of the amount of available RAM. This is supposed |
ab06eef8 | 1183 | to provide a more reliable default and limit a too aggressive |
c20d8298 KS |
1184 | paralellism for setups with 1000s of devices connected. |

1196 | CHANGES WITH 198: |
1197 | ||
1198 | * Configuration of unit files may now be extended via drop-in | |
1199 | files without having to edit/override the unit files | |
1200 | themselves. More specifically, if the administrator wants to | |
1201 | change one value for a service file foobar.service he can | |
1202 | now do so by dropping in a configuration snippet into | |
ad88e758 | 1203 | /etc/systemd/system/foobar.service.d/*.conf. The unit logic |
85d68397 LP |
1204 | will load all these snippets and apply them on top of the |
1205 | main unit configuration file, possibly extending or | |
1206 | overriding its settings. Using these drop-in snippets is | |
40e21da8 KS |
1207 | generally nicer than the two earlier options for changing |
1208 | unit files locally: copying the files from | |
85d68397 LP |
1209 | /usr/lib/systemd/system/ to /etc/systemd/system/ and editing |
1210 | them there; or creating a new file in /etc/systemd/system/ | |
1211 | that incorporates the original one via ".include". Drop-in | |
1212 | snippets into these .d/ directories can be placed in any | |
fd868975 | 1213 | directory systemd looks for units in, and the usual |
85d68397 LP |
1214 | overriding semantics between /usr/lib, /etc and /run apply |
1215 | for them too. | |
1216 | ||
1217 | * Most unit file settings which take lists of items can now be | |
6aa8d43a | 1218 | reset by assigning the empty string to them. For example, |
85d68397 LP |
1219 | normally, settings such as Environment=FOO=BAR append a new |
1220 | environment variable assignment to the environment block, | |
1221 | each time they are used. By assigning Environment= the empty | |
1222 | string the environment block can be reset to empty. This is | |
1223 | particularly useful with the .d/*.conf drop-in snippets | |
156f7d09 KS |
1224 | mentioned above, since this adds the ability to reset list |
1225 | settings from vendor unit files via these drop-ins. | |
85d68397 LP |
1226 | |
1227 | * systemctl gained a new "list-dependencies" command for | |
1228 | listing the dependencies of a unit recursively. | |
1229 | ||
40e21da8 | 1230 | * Inhibitors are now honored and listed by "systemctl |
85d68397 LP |
1231 | suspend", "systemctl poweroff" (and similar) too, not only |
1232 | GNOME. These commands will also list active sessions by | |
1233 | other users. | |
1234 | ||
1235 | * Resource limits (as exposed by the various control group | |
1236 | controllers) can now be controlled dynamically at runtime | |
1237 | for all units. More specifically, you can now use a command | |
1238 | like "systemctl set-cgroup-attr foobar.service cpu.shares | |
1239 | 2000" to alter the CPU shares a specific service gets. These | |
6aa8d43a | 1240 | settings are stored persistently on disk, and thus allow the |
85d68397 LP |
1241 | administrator to easily adjust the resource usage of |
1242 | services with a few simple commands. This dynamic resource | |
6aa8d43a | 1243 | management logic is also available to other programs via the |
85d68397 LP |
1244 | bus. Almost any kernel cgroup attribute and controller is |
1245 | supported. | |
1246 | ||
1247 | * systemd-vconsole-setup will now copy all font settings to | |
6aa8d43a LP |
1248 | all allocated VTs, where it previously applied them only to |
1249 | the foreground VT. | |
85d68397 LP |
1250 | |
1251 | * libsystemd-login gained the new sd_session_get_tty() API | |
1252 | call. | |
1253 | ||
6aa8d43a LP |
1254 | * This release drops support for a few legacy or |
1255 | distribution-specific LSB facility names when parsing init | |
1256 | scripts: $x-display-manager, $mail-transfer-agent, | |
85d68397 LP |
1257 | $mail-transport-agent, $mail-transfer-agent, $smtp, |
1258 | $null. Also, the mail-transfer-agent.target unit backing | |
1259 | this has been removed. Distributions which want to retain | |
6aa8d43a LP |
1260 | compatibility with this should carry the burden for |
1261 | supporting this themselves and patch support for these back | |
1262 | in, if they really need to. Also, the facilities $syslog and | |
1263 | $local_fs are now ignored, since systemd does not support | |
1264 | early-boot LSB init scripts anymore, and these facilities | |
1265 | are implied anyway for normal services. syslog.target has | |
1266 | also been removed. | |
85d68397 | 1267 | |
40e21da8 | 1268 | * There are new bus calls on PID1's Manager object for |
6aa8d43a | 1269 | cancelling jobs, and removing snapshot units. Previously, |
85d68397 LP |
1270 | both calls were only available on the Job and Snapshot |
1271 | objects themselves. | |
1272 | ||
1273 | * systemd-journal-gatewayd gained SSL support. | |
1274 | ||
1275 | * The various "environment" files, such as /etc/locale.conf | |
1276 | now support continuation lines with a backslash ("\") as | |
1277 | last character in the line, similar in style (but different) | |
1278 | to how this is supported in shells. | |
1279 | ||
1280 | * For normal user processes the _SYSTEMD_USER_UNIT= field is | |
1281 | now implicitly appended to every log entry logged. systemctl | |
1282 | has been updated to filter by this field when operating on a | |
1283 | user systemd instance. | |
1284 | ||
1285 | * nspawn will now implicitly add the CAP_AUDIT_WRITE and | |
1286 | CAP_AUDIT_CONTROL capabilities to the capabilities set for | |
1287 | the container. This makes it easier to boot unmodified | |
1288 | Fedora systems in a container, which however still requires | |
1289 | audit=0 to be passed on the kernel command line. Auditing in | |
1290 | kernel and userspace is unfortunately still too broken in | |
1291 | context of containers, hence we recommend compiling it out | |
1292 | of the kernel or using audit=0. Hopefully this will be fixed | |
1293 | one day for good in the kernel. | |
1294 | ||
1295 | * nspawn gained the new --bind= and --bind-ro= parameters to | |
1296 | bind mount specific directories from the host into the | |
1297 | container. | |
1298 | ||
40e21da8 | 1299 | * nspawn will now mount its own devpts file system instance |
6aa8d43a | 1300 | into the container, in order not to leak pty devices from |
85d68397 LP |
1301 | the host into the container. |
1302 | ||
1303 | * systemd will now read the firmware boot time performance | |
6aa8d43a LP |
1304 | information from the EFI variables, if the used boot loader |
1305 | supports this, and takes it into account for boot performance | |
1306 | analysis via "systemd-analyze". This is currently supported | |
1307 | only in conjunction with Gummiboot, but could be supported | |
1308 | by other boot loaders too. For details see: | |
85d68397 LP |
1309 | |
1310 | http://www.freedesktop.org/wiki/Software/systemd/BootLoaderInterface | |
1311 | ||
1312 | * A new generator has been added that automatically mounts the | |
1313 | EFI System Partition (ESP) to /boot, if that directory | |
6aa8d43a LP |
1314 | exists, is empty, and no other file system has been |
1315 | configured to be mounted there. | |
85d68397 LP |
1316 | |
1317 | * logind will now send out PrepareForSleep(false) out | |
1318 | unconditionally, after coming back from suspend. This may be | |
1319 | used by applications as asynchronous notification for | |
1320 | system resume events. | |
1321 | ||
1322 | * "systemctl unlock-sessions" has been added, that allows | |
1323 | unlocking the screens of all user sessions at once, similar | |
1324 | how "systemctl lock-sessions" already locked all users | |
40e21da8 | 1325 | sessions. This is backed by a new D-Bus call UnlockSessions(). |
85d68397 LP |
1326 | |
1327 | * "loginctl seat-status" will now show the master device of a | |
1328 | seat. (i.e. the device of a seat that needs to be around for | |
1329 | the seat to be considered available, usually the graphics | |
1330 | card). | |
1331 | ||
1332 | * tmpfiles gained a new "X" line type, that allows | |
1333 | configuration of files and directories (with wildcards) that | |
1334 | shall be excluded from automatic cleanup ("aging"). | |
1335 | ||
bf933560 KS |
1336 | * udev default rules set the device node permissions now only |
1337 | at "add" events, and do not change them any longer with a | |
1338 | later "change" event. | |
85d68397 LP |
1339 | |
1340 | * The log messages for lid events and power/sleep keypresses | |
1341 | now carry a message ID. | |
1342 | ||
1343 | * We now have a substantially larger unit test suite, but this | |
1344 | continues to be work in progress. | |
1345 | ||
1346 | * udevadm hwdb gained a new --root= parameter to change the | |
1347 | root directory to operate relative to. | |
1348 | ||
40e21da8 KS |
1349 | * logind will now issue a background sync() request to the kernel |
1350 | early at shutdown, so that dirty buffers are flushed to disk early | |
85d68397 LP |
1351 | instead of at the last moment, in order to optimize shutdown |
1352 | times a little. | |
1353 | ||
1354 | * A new bootctl tool has been added that is an interface for | |
1355 | certain boot loader operations. This is currently a preview | |
1356 | and is likely to be extended into a small mechanism daemon | |
1357 | like timedated, localed, hostnamed, and can be used by | |
1358 | graphical UIs to enumerate available boot options, and | |
1359 | request boot into firmware operations. | |
1360 | ||
1361 | * systemd-bootchart has been relicensed to LGPLv2.1+ to match | |
1362 | the rest of the package. It also has been updated to work | |
1363 | correctly in initrds. | |
1364 | ||
1365 | * Policykit previously has been runtime optional, and is now | |
1366 | also compile time optional via a configure switch. | |
1367 | ||
1368 | * systemd-analyze has been reimplemented in C. Also "systemctl | |
1369 | dot" has moved into systemd-analyze. | |
1370 | ||
1371 | * "systemctl status" with no further parameters will now print | |
1372 | the status of all active or failed units. | |
1373 | ||
1374 | * Operations such as "systemctl start" can now be executed | |
1375 | with a new mode "--irreversible" which may be used to queue | |
1376 | operations that cannot accidentally be reversed by a later | |
6aa8d43a | 1377 | job queuing. This is by default used to make shutdown |
85d68397 LP |
1378 | requests more robust. |
1379 | ||
1380 | * The Python API of systemd now gained a new module for | |
1381 | reading journal files. | |
1382 | ||
1383 | * A new tool kernel-install has been added that can install | |
1384 | kernel images according to the Boot Loader Specification: | |
1385 | ||
1386 | http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec | |
1387 | ||
1388 | * Boot time console output has been improved to provide | |
6aa8d43a | 1389 | animated boot time output for hanging jobs. |
85d68397 LP |
1390 | |
1391 | * A new tool systemd-activate has been added which can be used | |
1392 | to test socket activation with, directly from the command | |
1393 | line. This should make it much easier to test and debug | |
1394 | socket activation in daemons. | |
1395 | ||
1396 | * journalctl gained a new "--reverse" (or -r) option to show | |
1397 | journal output in reverse order (i.e. newest line first). | |
1398 | ||
43447fb7 LP |
1399 | * journalctl gained a new "--pager-end" (or -e) option to jump |
1400 | to immediately jump to the end of the journal in the | |
1401 | pager. This is only supported in conjunction with "less". | |
1402 | ||
85d68397 LP |
1403 | * journalctl gained a new "--user-unit=" option, that works |
1404 | similar to "--unit=" but filters for user units rather than | |
1405 | system units. | |
1406 | ||
1407 | * A number of unit files to ease adoption of systemd in | |
1408 | initrds has been added. This moves some minimal logic from | |
1409 | the various initrd implementations into systemd proper. | |
1410 | ||
1411 | * The journal files are now owned by a new group | |
1412 | "systemd-journal", which exists specifically to allow access | |
1413 | to the journal, and nothing else. Previously, we used the | |
6aa8d43a | 1414 | "adm" group for that, which however possibly covers more |
85d68397 LP |
1415 | than just journal/log file access. This new group is now |
1416 | already used by systemd-journal-gatewayd to ensure this | |
1417 | daemon gets access to the journal files and as little else | |
1418 | as possible. Note that "make install" will also set FS ACLs | |
1419 | up for /var/log/journal to give "adm" and "wheel" read | |
1420 | access to it, in addition to "systemd-journal" which owns | |
1421 | the journal files. We recommend that packaging scripts also | |
6aa8d43a | 1422 | add read access to "adm" + "wheel" to /var/log/journal, and |
85d68397 LP |
1423 | all existing/future journal files. To normal users and |
1424 | administrators little changes, however packagers need to | |
1425 | ensure to create the "systemd-journal" system group at | |
1426 | package installation time. | |
1427 | ||
1428 | * The systemd-journal-gatewayd now runs as unprivileged user | |
1429 | systemd-journal-gateway:systemd-journal-gateway. Packaging | |
1430 | scripts need to create these system user/group at | |
1431 | installation time. | |
1432 | ||
1433 | * timedated now exposes a new boolean property CanNTP that | |
1434 | indicates whether a local NTP service is available or not. | |
1435 | ||
1436 | * systemd-detect-virt will now also detect xen PVs | |
1437 | ||
40e21da8 KS |
1438 | * The pstore file system is now mounted by default, if it is |
1439 | available. | |
85d68397 | 1440 | |
1aed4590 LP |
1441 | * In addition to the SELinux and IMA policies we will now also |
1442 | load SMACK policies at early boot. | |

1459 | CHANGES WITH 197: |
1460 | ||
1461 | * Timer units now support calendar time events in addition to | |
1462 | monotonic time events. That means you can now trigger a unit | |
1463 | based on a calendar time specification such as "Thu,Fri | |
1464 | 2013-*-1,5 11:12:13" which refers to 11:12:13 of the first | |
1465 | or fifth day of any month of the year 2013, given that it is | |
1466 | a thursday or friday. This brings timer event support | |
1467 | considerably closer to cron's capabilities. For details on | |
1468 | the supported calendar time specification language see | |
1469 | systemd.time(7). | |
1470 | ||
1471 | * udev now supports a number of different naming policies for | |
1472 | network interfaces for predictable names, and a combination | |
1473 | of these policies is now the default. Please see this wiki | |
1474 | document for details: | |
1475 | ||
1476 | http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames | |
1477 | ||
1478 | * Auke Kok's bootchart implementation has been added to the | |
1479 | systemd tree. It's an optional component that can graph the | |
1480 | boot in quite some detail. It's one of the best bootchart | |
1481 | implementations around and minimal in its code and | |
1482 | dependencies. | |
1483 | ||
1484 | * nss-myhostname has been integrated into the systemd source | |
1485 | tree. nss-myhostname guarantees that the local hostname | |
1486 | always stays resolvable via NSS. It has been a weak | |
1487 | requirement of systemd-hostnamed since a long time, and | |
1488 | since its code is actually trivial we decided to just | |
1489 | include it in systemd's source tree. It can be turned off | |
1490 | with a configure switch. | |
1491 | ||
1492 | * The read-ahead logic is now capable of properly detecting | |
1493 | whether a btrfs file system is on SSD or rotating media, in | |
1494 | order to optimize the read-ahead scheme. Previously, it was | |
1495 | only capable of detecting this on traditional file systems | |
1496 | such as ext4. | |
1497 | ||
1498 | * In udev, additional device properties are now read from the | |
1499 | IAB in addition to the OUI database. Also, Bluetooth company | |
1500 | identities are attached to the devices as well. | |
1501 | ||
1502 | * In service files %U may be used as specifier that is | |
1503 | replaced by the configured user name of the service. | |
1504 | ||
1505 | * nspawn may now be invoked without a controlling TTY. This | |
1506 | makes it suitable for invocation as its own service. This | |
1507 | may be used to set up a simple containerized server system | |
1508 | using only core OS tools. | |
1509 | ||
1510 | * systemd and nspawn can now accept socket file descriptors | |
1511 | when they are started for socket activation. This enables | |
1512 | implementation of socket activated nspawn | |
1513 | containers. i.e. think about autospawning an entire OS image | |
1514 | when the first SSH or HTTP connection is received. We expect | |
1515 | that similar functionality will also be added to libvirt-lxc | |
1516 | eventually. | |
1517 | ||
1518 | * journalctl will now suppress ANSI color codes when | |
1519 | presenting log data. | |
1520 | ||
1521 | * systemctl will no longer show control group information for | |
1522 | a unit if a the control group is empty anyway. | |
1523 | ||
1524 | * logind can now automatically suspend/hibernate/shutdown the | |
1525 | system on idle. | |
1526 | ||
1527 | * /etc/machine-info and hostnamed now also expose the chassis | |
1528 | type of the system. This can be used to determine whether | |
1529 | the local system is a laptop, desktop, handset or | |
1530 | tablet. This information may either be configured by the | |
1531 | user/vendor or is automatically determined from ACPI and DMI | |
1532 | information if possible. | |
1533 | ||
1534 | * A number of PolicyKit actions are now bound together with | |
1535 | "imply" rules. This should simplify creating UIs because | |
1536 | many actions will now authenticate similar ones as well. | |
1537 | ||
1538 | * Unit files learnt a new condition ConditionACPower= which | |
1539 | may be used to conditionalize a unit depending on whether an | |
1540 | AC power source is connected or not, of whether the system | |
1541 | is running on battery power. | |
1542 | ||
1543 | * systemctl gained a new "is-failed" verb that may be used in | |
1544 | shell scripts and suchlike to check whether a specific unit | |
1545 | is in the "failed" state. | |
1546 | ||
1547 | * The EnvironmentFile= setting in unit files now supports file | |
1548 | globbing, and can hence be used to easily read a number of | |
1549 | environment files at once. | |
1550 | ||
1551 | * systemd will no longer detect and recognize specific | |
1552 | distributions. All distribution-specific #ifdeffery has been | |
1553 | removed, systemd is now fully generic and | |
1554 | distribution-agnostic. Effectively, not too much is lost as | |
1555 | a lot of the code is still accessible via explicit configure | |
1556 | switches. However, support for some distribution specific | |
1557 | legacy configuration file formats has been dropped. We | |
1558 | recommend distributions to simply adopt the configuration | |
1559 | files everybody else uses now and convert the old | |
1560 | configuration from packaging scripts. Most distributions | |
1561 | already did that. If that's not possible or desirable, | |
1562 | distributions are welcome to forward port the specific | |
1563 | pieces of code locally from the git history. | |
1564 | ||
1565 | * When logging a message about a unit systemd will now always | |
1566 | log the unit name in the message meta data. | |
1567 | ||
1568 | * localectl will now also discover system locale data that is | |
1569 | not stored in locale archives, but directly unpacked. | |
1570 | ||
1571 | * logind will no longer unconditionally use framebuffer | |
1572 | devices as seat masters, i.e. as devices that are required | |
1573 | to be existing before a seat is considered preset. Instead, | |
1574 | it will now look for all devices that are tagged as | |
1575 | "seat-master" in udev. By default framebuffer devices will | |
1576 | be marked as such, but depending on local systems other | |
1577 | devices might be marked as well. This may be used to | |
1578 | integrate graphics cards using closed source drivers (such | |
1579 | as NVidia ones) more nicely into logind. Note however, that | |
1580 | we recommend using the open source NVidia drivers instead, | |
1581 | and no udev rules for the closed-source drivers will be | |
1582 | shipped from us upstream. | |

1598 | CHANGES WITH 196: |
1599 | ||
1600 | * udev gained support for loading additional device properties | |
1601 | from an indexed database that is keyed by vendor/product IDs | |
1602 | and similar device identifiers. For the beginning this | |
1603 | "hwdb" is populated with data from the well-known PCI and | |
1604 | USB database, but also includes PNP, ACPI and OID data. In | |
1605 | the longer run this indexed database shall grow into | |
1606 | becoming the one central database for non-essential | |
1607 | userspace device metadata. Previously, data from the PCI/USB | |
96ec33c0 | 1608 | database was only attached to select devices, since the |
0428ddb7 | 1609 | lookup was a relatively expensive operation due to O(n) time |
96ec33c0 LP |
1610 | complexity (with n being the number of entries in the |
1611 | database). Since this is now O(1), we decided to add in this | |
1612 | data for all devices where this is available, by | |
0428ddb7 LP |
1613 | default. Note that the indexed database needs to be rebuilt |
1614 | when new data files are installed. To achieve this you need | |
1615 | to update your packaging scripts to invoke "udevadm hwdb | |
1616 | --update" after installation of hwdb data files. For | |
1617 | RPM-based distributions we introduced the new | |
1618 | %udev_hwdb_update macro for this purpose. | |
1619 | ||
1620 | * The Journal gained support for the "Message Catalog", an | |
1621 | indexed database to link up additional information with | |
1622 | journal entries. For further details please check: | |
1623 | ||
1624 | http://www.freedesktop.org/wiki/Software/systemd/catalog | |
1625 | ||
1626 | The indexed message catalog database also needs to be | |
1627 | rebuilt after installation of message catalog files. Use | |
1628 | "journalctl --update-catalog" for this. For RPM-based | |
1629 | distributions we introduced the %journal_catalog_update | |
1630 | macro for this purpose. | |
1631 | ||
1632 | * The Python Journal bindings gained support for the standard | |
1633 | Python logging framework. | |
1634 | ||
1635 | * The Journal API gained new functions for checking whether | |
1636 | the underlying file system of a journal file is capable of | |
1637 | properly reporting file change notifications, or whether | |
1638 | applications that want to reflect journal changes "live" | |
ab06eef8 | 1639 | need to recheck journal files continuously in appropriate |
0428ddb7 LP |
1640 | time intervals. |
1641 | ||
1642 | * It is now possible to set the "age" field for tmpfiles | |
1643 | entries to 0, indicating that files matching this entry | |
1644 | shall always be removed when the directories are cleaned up. | |
1645 | ||
1646 | * coredumpctl gained a new "gdb" verb which invokes gdb | |
1647 | right-away on the selected coredump. | |
1648 | ||
1649 | * There's now support for "hybrid sleep" on kernels that | |
1650 | support this, in addition to "suspend" and "hibernate". Use | |
1651 | "systemctl hybrid-sleep" to make use of this. | |
1652 | ||
1653 | * logind's HandleSuspendKey= setting (and related settings) | |
1654 | now gained support for a new "lock" setting to simply | |
1655 | request the screen lock on all local sessions, instead of | |
1656 | actually executing a suspend or hibernation. | |
1657 | ||
1658 | * systemd will now mount the EFI variables file system by | |
1659 | default. | |
1660 | ||
1661 | * Socket units now gained support for configuration of the | |
1662 | SMACK security label. | |
1663 | ||
1664 | * timedatectl will now output the time of the last and next | |
1665 | daylight saving change. | |
1666 | ||
1667 | * We dropped support for various legacy and distro-specific | |
1668 | concepts, such as insserv, early-boot SysV services | |
1669 | (i.e. those for non-standard runlevels such as 'b' or 'S') | |
1670 | or ArchLinux /etc/rc.conf support. We recommend the | |
1671 | distributions who still need support this to either continue | |
1672 | to maintain the necessary patches downstream, or find a | |
1673 | different solution. (Talk to us if you have questions!) | |
1674 | ||
1675 | * Various systemd components will now bypass PolicyKit checks | |
1676 | for root and otherwise handle properly if PolicyKit is not | |
1677 | found to be around. This should fix most issues for | |
1678 | PolicyKit-less systems. Quite frankly this should have been | |
1679 | this way since day one. It is absolutely our intention to | |
1680 | make systemd work fine on PolicyKit-less systems, and we | |
1681 | consider it a bug if something doesn't work as it should if | |
1682 | PolicyKit is not around. | |
1683 | ||
1684 | * For embedded systems it is now possible to build udev and | |
1685 | systemd without blkid and/or kmod support. | |
1686 | ||
1687 | * "systemctl switch-root" is now capable of switching root | |
1688 | more than once. I.e. in addition to transitions from the | |
1689 | initrd to the host OS it is now possible to transition to | |
1690 | further OS images from the host. This is useful to implement | |
1691 | offline updating tools. | |
1692 | ||
1693 | * Various other additions have been made to the RPM macros | |
1694 | shipped with systemd. Use %udev_rules_update() after | |
1695 | installing new udev rules files. %_udevhwdbdir, | |
1696 | %_udevrulesdir, %_journalcatalogdir, %_tmpfilesdir, | |
1697 | %_sysctldir are now available which resolve to the right | |
1698 | directories for packages to place various data files in. | |
1699 | ||
1700 | * journalctl gained the new --full switch (in addition to | |
1701 | --all, to disable ellipsation for long messages. | |

139ee8cc LP |
1713 | CHANGES WITH 195: |
1714 | ||
6827101a | 1715 | * journalctl gained new --since= and --until= switches to |
139ee8cc LP |
1716 | filter by time. It also now supports nice filtering for |
1717 | units via --unit=/-u. | |
1718 | ||
6827101a | 1719 | * Type=oneshot services may use ExecReload= and do the |
139ee8cc LP |
1720 | right thing. |
1721 | ||
1722 | * The journal daemon now supports time-based rotation and | |
1723 | vacuuming, in addition to the usual disk-space based | |
1724 | rotation. | |
1725 | ||
1726 | * The journal will now index the available field values for | |
1727 | each field name. This enables clients to show pretty drop | |
1728 | downs of available match values when filtering. The bash | |
1729 | completion of journalctl has been updated | |
1730 | accordingly. journalctl gained a new switch -F to list all | |
1731 | values a certain field takes in the journal database. | |
1732 | ||
1733 | * More service events are now written as structured messages | |
1734 | to the journal, and made recognizable via message IDs. | |
1735 | ||
1736 | * The timedated, localed and hostnamed mini-services which | |
1737 | previously only provided support for changing time, locale | |
1738 | and hostname settings from graphical DEs such as GNOME now | |
1739 | also have a minimal (but very useful) text-based client | |
1740 | utility each. This is probably the nicest way to changing | |
1741 | these settings from the command line now, especially since | |
1742 | it lists available options and is fully integrated with bash | |
1743 | completion. | |
1744 | ||
1745 | * There's now a new tool "systemd-coredumpctl" to list and | |
1746 | extract coredumps from the journal. | |
1747 | ||
1748 | * We now install a README each in /var/log/ and | |
1749 | /etc/rc.d/init.d explaining where the system logs and init | |
1750 | scripts went. This hopefully should help folks who go to | |
1751 | that dirs and look into the otherwise now empty void and | |
1752 | scratch their heads. | |
1753 | ||
1754 | * When user-services are invoked (by systemd --user) the | |
1755 | $MANAGERPID env var is set to the PID of systemd. | |
1756 | ||
1757 | * SIGRTMIN+24 when sent to a --user instance will now result | |
1758 | in immediate termination of systemd. | |
1759 | ||
1760 | * gatewayd received numerous feature additions such as a | |
1761 | "follow" mode, for live syncing and filtering. | |
1762 | ||
1763 | * browse.html now allows filtering and showing detailed | |
1764 | information on specific entries. Keyboard navigation and | |
1765 | mouse screen support has been added. | |
1766 | ||
1767 | * gatewayd/journalctl now supports HTML5/JSON | |
1768 | Server-Sent-Events as output. | |
1769 | ||
1cb88f2c | 1770 | * The SysV init script compatibility logic will now |
139ee8cc LP |
1771 | heuristically determine whether a script supports the |
1772 | "reload" verb, and only then make this available as | |
1773 | "systemctl reload". | |
1774 | ||
15f47220 | 1775 | * "systemctl status --follow" has been removed, use "journalctl |
139ee8cc LP |
1776 | -u" instead. |
1777 | ||
1778 | * journald.conf's RuntimeMinSize=, PersistentMinSize= settings | |
1779 | have been removed since they are hardly useful to be | |
1780 | configured. | |
1781 | ||
1782 | * And I'd like to take the opportunity to specifically mention | |
1783 | Zbigniew for his great contributions. Zbigniew, you rock! | |

1793 | CHANGES WITH 194: |
1794 | ||
1795 | * If /etc/vconsole.conf is non-existent or empty we will no | |
1796 | longer load any console font or key map at boot by | |
1797 | default. Instead the kernel defaults will be left | |
1798 | intact. This is definitely the right thing to do, as no | |
1799 | configuration should mean no configuration, and hard-coding | |
1800 | font names that are different on all archs is probably a bad | |
1801 | idea. Also, the kernel default key map and font should be | |
1802 | good enough for most cases anyway, and mostly identical to | |
1803 | the userspace fonts/key maps we previously overloaded them | |
1804 | with. If distributions want to continue to default to a | |
1805 | non-kernel font or key map they should ship a default | |
1806 | /etc/vconsole.conf with the appropriate contents. | |

1812 | CHANGES WITH 193: |
1813 | ||
1814 | * journalctl gained a new --cursor= switch to show entries | |
1815 | starting from the specified location in the journal. | |
1816 | ||
1817 | * We now enforce a size limit on journal entry fields exported | |
1818 | with "-o json" in journalctl. Fields larger than 4K will be | |
1819 | assigned null. This can be turned off with --all. | |
1820 | ||
1821 | * An (optional) journal gateway daemon is now available as | |
1822 | "systemd-journal-gatewayd.service". This service provides | |
1823 | access to the journal via HTTP and JSON. This functionality | |
1824 | will be used to implement live log synchronization in both | |
1825 | pull and push modes, but has various other users too, such | |
1826 | as easy log access for debugging of embedded devices. Right | |
1827 | now it is already useful to retrieve the journal via HTTP: | |
1828 | ||
1829 | # systemctl start systemd-journal-gatewayd.service | |
1830 | # wget http://localhost:19531/entries | |
1831 | ||
1832 | This will download the journal contents in a | |
1833 | /var/log/messages compatible format. The same as JSON: | |
1834 | ||
1835 | # curl -H"Accept: application/json" http://localhost:19531/entries | |
1836 | ||
1837 | This service is also accessible via a web browser where a | |
1838 | single static HTML5 app is served that uses the JSON logic | |
1839 | to enable the user to do some basic browsing of the | |
1840 | journal. This will be extended later on. Here's an example | |
1841 | screenshot of this app in its current state: | |

1848 | CHANGES WITH 192: |
1849 | ||
1850 | * The bash completion logic is now available for journalctl | |
1851 | too. | |
1852 | ||
1853 | * We don't mount the "cpuset" controller anymore together with | |
1854 | "cpu" and "cpuacct", as "cpuset" groups generally cannot be | |
1855 | started if no parameters are assigned to it. "cpuset" hence | |
1856 | broke code that assumed it it could create "cpu" groups and | |
1857 | just start them. | |
1858 | ||
1859 | * journalctl -f will now subscribe to terminal size changes, | |
1860 | and line break accordingly. | |

b6a86739 LP |
1865 | CHANGES WITH 191: |
1866 | ||
1867 | * nspawn will now create a symlink /etc/localtime in the | |
1868 | container environment, copying the host's timezone | |
1869 | setting. Previously this has been done via a bind mount, but | |
1870 | since symlinks cannot be bind mounted this has now been | |
1871 | changed to create/update the appropriate symlink. | |
1872 | ||
1873 | * journalctl -n's line number argument is now optional, and | |
1874 | will default to 10 if omitted. | |
1875 | ||
1876 | * journald will now log the maximum size the journal files may | |
1877 | take up on disk. This is particularly useful if the default | |
1878 | built-in logic of determining this parameter from the file | |
1879 | system size is used. Use "systemctl status | |
6563b535 | 1880 | systemd-journald.service" to see this information. |
b6a86739 LP |
1881 | |
1882 | * The multi-seat X wrapper tool has been stripped down. As X | |
1883 | is now capable of enumerating graphics devices via udev in a | |
1884 | seat-aware way the wrapper is not strictly necessary | |
1885 | anymore. A stripped down temporary stop-gap is still shipped | |
1886 | until the upstream display managers have been updated to | |
1887 | fully support the new X logic. Expect this wrapper to be | |
6563b535 | 1888 | removed entirely in one of the next releases. |
b6a86739 LP |
1889 | |
1890 | * HandleSleepKey= in logind.conf has been split up into | |
1891 | HandleSuspendKey= and HandleHibernateKey=. The old setting | |
6563b535 | 1892 | is not available anymore. X11 and the kernel are |
b6a86739 LP |
1893 | distuingishing between these keys and we should too. This |
1894 | also means the inhibition lock for these keys has been split | |
1895 | into two. | |

0c11f949 LP |
1900 | CHANGES WITH 190: |
1901 | ||
1902 | * Whenever a unit changes state we'll now log this to the | |
1903 | journal and show along the unit's own log output in | |
1904 | "systemctl status". | |
1905 | ||
1906 | * ConditionPathIsMountPoint= can now properly detect bind | |
1907 | mount points too. (Previously, a bind mount of one file | |
8d0256b7 | 1908 | system to another place in the same file system could not be |
0c11f949 LP |
1909 | detected as mount, since they shared struct stat's st_dev |
1910 | field.) | |
1911 | ||
1912 | * We will now mount the cgroup controllers cpu, cpuacct, | |
1913 | cpuset and the controllers net_cls, net_prio together by | |
1914 | default. | |
1915 | ||
1916 | * nspawn containers will now have a virtualized boot | |
1917 | ID. (i.e. /proc/sys/kernel/random/boot_id is now mounted | |
1918 | over with a randomized ID at container initialization). This | |
1919 | has the effect of making "journalctl -b" do the right thing | |
1920 | in a container. | |
1921 | ||
1922 | * The JSON output journal serialization has been updated not | |
1923 | to generate "endless" list objects anymore, but rather one | |
1924 | JSON object per line. This is more in line how most JSON | |
1925 | parsers expect JSON objects. The new output mode | |
1926 | "json-pretty" has been added to provide similar output, but | |
1927 | neatly aligned for readability by humans. | |
1928 | ||
1929 | * We dropped all explicit sync() invocations in the shutdown | |
1930 | code. The kernel does this implicitly anyway in the kernel | |
1931 | reboot() syscall. halt(8)'s -n option is now a compatibility | |
1932 | no-op. | |
1933 | ||
1934 | * We now support virtualized reboot() in containers, as | |
1935 | supported by newer kernels. We will fall back to exit() if | |
1936 | CAP_SYS_REBOOT is not available to the container. Also, | |
1937 | nspawn makes use of this now and will actually reboot the | |
1938 | container if the containerized OS asks for that. | |
1939 | ||
1940 | * journalctl will only show local log output by default | |
1941 | now. Use --merge (-m) to show remote log output, too. | |
1942 | ||
1943 | * libsystemd-journal gained the new sd_journal_get_usage() | |
1944 | call to determine the current disk usage of all journal | |
1945 | files. This is exposed in the new "journalctl --disk-usage" | |
1946 | command. | |
1947 | ||
1948 | * journald gained a new configuration setting SplitMode= in | |
1949 | journald.conf which may be used to control how user journals | |
1950 | are split off. See journald.conf(5) for details. | |
1951 | ||
1952 | * A new condition type ConditionFileNotEmpty= has been added. | |
1953 | ||
1954 | * tmpfiles' "w" lines now support file globbing, to write | |
1955 | multiple files at once. | |
1956 | ||
1957 | * We added Python bindings for the journal submission | |
1958 | APIs. More Python APIs for a number of selected APIs will | |
1959 | likely follow. Note that we intend to add native bindings | |
1960 | only for the Python language, as we consider it common | |
1961 | enough to deserve bindings shipped within systemd. There are | |
1962 | various projects outside of systemd that provide bindings | |
1963 | for languages such as PHP or Lua. | |
1964 | ||
a98d5d64 LP |
1965 | * Many conditions will now resolve specifiers such as %i. In |
1966 | addition, PathChanged= and related directives of .path units | |
1967 | now support specifiers as well. | |
0c11f949 LP |
1968 | |
1969 | * There's now a new RPM macro definition for the system preset | |
1970 | dir: %_presetdir. | |
1971 | ||
ab06eef8 | 1972 | * journald will now warn if it can't forward a message to the |
0c11f949 LP |
1973 | syslog daemon because it's socket is full. |
1974 | ||
1975 | * timedated will no longer write or process /etc/timezone, | |
1976 | except on Debian. As we do not support late mounted /usr | |
1977 | anymore /etc/localtime always being a symlink is now safe, | |
1978 | and hence the information in /etc/timezone is not necessary | |
1979 | anymore. | |
1980 | ||
aaccc32c | 1981 | * logind will now always reserve one VT for a text getty (VT6 |
0c11f949 LP |
1982 | by default). Previously if more than 6 X sessions where |
1983 | started they took up all the VTs with auto-spawned gettys, | |
1984 | so that no text gettys were available anymore. | |
1985 | ||
1986 | * udev will now automatically inform the btrfs kernel logic | |
1987 | about btrfs RAID components showing up. This should make | |
1988 | simple hotplug based btrfs RAID assembly work. | |
1989 | ||
1990 | * PID 1 will now increase its RLIMIT_NOFILE to 64K by default | |
1991 | (but not for its children which will stay at the kernel | |
1992 | default). This should allow setups with a lot more listening | |
1993 | sockets. | |
1994 | ||
1995 | * systemd will now always pass the configured timezone to the | |
1996 | kernel at boot. timedated will do the same when the timezone | |
1997 | is changed. | |
1998 | ||
1999 | * logind's inhibition logic has been updated. By default, | |
2000 | logind will now handle the lid switch, the power and sleep | |
2001 | keys all the time, even in graphical sessions. If DEs want | |
2002 | to handle these events on their own they should take the new | |
2003 | handle-power-key, handle-sleep-key and handle-lid-switch | |
2004 | inhibitors during their runtime. A simple way to achiveve | |
2005 | that is to invoke the DE wrapped in an invocation of: | |
2006 | ||
2007 | systemd-inhibit --what=handle-power-key:handle-sleep-key:handle-lid-switch ... | |
2008 | ||
2009 | * Access to unit operations is now checked via SELinux taking | |
2010 | the unit file label and client process label into account. | |
2011 | ||
aad803af LP |
2012 | * systemd will now notify the administrator in the journal |
2013 | when he over-mounts a non-empty directory. | |
2014 | ||
2015 | * There are new specifiers that are resolved in unit files, | |
2016 | for the host name (%H), the machine ID (%m) and the boot ID | |
2017 | (%b). | |

2027 | CHANGES WITH 189: |
2028 | ||
2029 | * Support for reading structured kernel messages from | |
2030 | /dev/kmsg has now been added and is enabled by default. | |
2031 | ||
2032 | * Support for reading kernel messages from /proc/kmsg has now | |
2033 | been removed. If you want kernel messages in the journal | |
2034 | make sure to run a recent kernel (>= 3.5) that supports | |
2035 | reading structured messages from /dev/kmsg (see | |
2036 | above). /proc/kmsg is now exclusive property of classic | |
2037 | syslog daemons again. | |
2038 | ||
2039 | * The libudev API gained the new | |
2040 | udev_device_new_from_device_id() call. | |
2041 | ||
2042 | * The logic for file system namespace (ReadOnlyDirectory=, | |
2043 | ReadWriteDirectoy=, PrivateTmp=) has been reworked not to | |
2044 | require pivot_root() anymore. This means fewer temporary | |
2045 | directories are created below /tmp for this feature. | |
2046 | ||
2047 | * nspawn containers will now see and receive all submounts | |
2048 | made on the host OS below the root file system of the | |
2049 | container. | |
2050 | ||
2051 | * Forward Secure Sealing is now supported for Journal files, | |
2052 | which provide cryptographical sealing of journal files so | |
2053 | that attackers cannot alter log history anymore without this | |
2054 | being detectable. Lennart will soon post a blog story about | |
2055 | this explaining it in more detail. | |
2056 | ||
2057 | * There are two new service settings RestartPreventExitStatus= | |
2058 | and SuccessExitStatus= which allow configuration of exit | |
2059 | status (exit code or signal) which will be excepted from the | |
2060 | restart logic, resp. consider successful. | |
2061 | ||
2062 | * journalctl gained the new --verify switch that can be used | |
2063 | to check the integrity of the structure of journal files and | |
2064 | (if Forward Secure Sealing is enabled) the contents of | |
2065 | journal files. | |
2066 | ||
2067 | * nspawn containers will now be run with /dev/stdin, /dev/fd/ | |
2068 | and similar symlinks pre-created. This makes running shells | |
2069 | as container init process a lot more fun. | |
2070 | ||
2071 | * The fstab support can now handle PARTUUID= and PARTLABEL= | |
2072 | entries. | |
2073 | ||
2074 | * A new ConditionHost= condition has been added to match | |
2075 | against the hostname (with globs) and machine ID. This is | |
2076 | useful for clusters where a single OS image is used to | |
2077 | provision a large number of hosts which shall run slightly | |
2078 | different sets of services. | |
2079 | ||
2080 | * Services which hit the restart limit will now be placed in a | |
2081 | failure state. | |

2087 | CHANGES WITH 188: |
2088 | ||
2089 | * When running in --user mode systemd will now become a | |
2090 | subreaper (PR_SET_CHILD_SUBREAPER). This should make the ps | |
2091 | tree a lot more organized. | |
2092 | ||
2093 | * A new PartOf= unit dependency type has been introduced that | |
2094 | may be used to group services in a natural way. | |
2095 | ||
2096 | * "systemctl enable" may now be used to enable instances of | |
2097 | services. | |
2098 | ||
2099 | * journalctl now prints error log levels in red, and | |
2100 | warning/notice log levels in bright white. It also supports | |
2101 | filtering by log level now. | |
2102 | ||
2103 | * cgtop gained a new -n switch (similar to top), to configure | |
2104 | the maximum number of iterations to run for. It also gained | |
2105 | -b, to run in batch mode (accepting no input). | |
2106 | ||
ab06eef8 | 2107 | * The suffix ".service" may now be omitted on most systemctl |
c269cec3 LP |
2108 | command lines involving service unit names. |
2109 | ||
2110 | * There's a new bus call in logind to lock all sessions, as | |
2111 | well as a loginctl verb for it "lock-sessions". | |
2112 | ||
2113 | * libsystemd-logind.so gained a new call sd_journal_perror() | |
2114 | that works similar to libc perror() but logs to the journal | |
2115 | and encodes structured information about the error number. | |
2116 | ||
2117 | * /etc/crypttab entries now understand the new keyfile-size= | |
2118 | option. | |
2119 | ||
2120 | * shutdown(8) now can send a (configurable) wall message when | |
2121 | a shutdown is cancelled. | |
2122 | ||
2123 | * The mount propagation mode for the root file system will now | |
2124 | default to "shared", which is useful to make containers work | |
2125 | nicely out-of-the-box so that they receive new mounts from | |
2126 | the host. This can be undone locally by running "mount | |
2127 | --make-rprivate /" if needed. | |
2128 | ||
2129 | * The prefdm.service file has been removed. Distributions | |
2130 | should maintain this unit downstream if they intend to keep | |
2131 | it around. However, we recommend writing normal unit files | |
2132 | for display managers instead. | |
2133 | ||
2134 | * Since systemd is a crucial part of the OS we will now | |
2135 | default to a number of compiler switches that improve | |
2136 | security (hardening) such as read-only relocations, stack | |
2137 | protection, and suchlike. | |
2138 | ||
2139 | * The TimeoutSec= setting for services is now split into | |
2140 | TimeoutStartSec= and TimeoutStopSec= to allow configuration | |
2141 | of individual time outs for the start and the stop phase of | |
2142 | the service. | |

c4f1b862 LP |
2151 | CHANGES WITH 187: |
2152 | ||
2153 | * The journal and id128 C APIs are now fully documented as man | |
2154 | pages. | |
2155 | ||
2156 | * Extra safety checks have been added when transitioning from | |
2157 | the initial RAM disk to the main system to avoid accidental | |
2158 | data loss. | |
2159 | ||
c269cec3 | 2160 | * /etc/crypttab entries now understand the new keyfile-offset= |
c4f1b862 LP |
2161 | option. |
2162 | ||
2163 | * systemctl -t can now be used to filter by unit load state. | |
2164 | ||
2165 | * The journal C API gained the new sd_journal_wait() call to | |
2166 | make writing synchronous journal clients easier. | |
2167 | ||
2168 | * journalctl gained the new -D switch to show journals from a | |
2169 | specific directory. | |
2170 | ||
2171 | * journalctl now displays a special marker between log | |
2172 | messages of two different boots. | |
2173 | ||
2174 | * The journal is now explicitly flushed to /var via a service | |
2175 | systemd-journal-flush.service, rather than implicitly simply | |
2176 | by seeing /var/log/journal to be writable. | |
2177 | ||
2178 | * journalctl (and the journal C APIs) can now match for much | |
2179 | more complex expressions, with alternatives and | |
2180 | disjunctions. | |
2181 | ||
2182 | * When transitioning from the initial RAM disk to the main | |
2183 | system we will now kill all processes in a killing spree to | |
2184 | ensure no processes stay around by accident. | |
2185 | ||
2186 | * Three new specifiers may be used in unit files: %u, %h, %s | |
2187 | resolve to the user name, user home directory resp. user | |
2188 | shell. This is useful for running systemd user instances. | |
2189 | ||
2190 | * We now automatically rotate journal files if their data | |
2191 | object hash table gets a fill level > 75%. We also size the | |
2192 | hash table based on the configured maximum file size. This | |
2193 | together should lower hash collisions drastically and thus | |
2194 | speed things up a bit. | |
2195 | ||
2196 | * journalctl gained the new "--header" switch to introspect | |
2197 | header data of journal files. | |
2198 | ||
2199 | * A new setting SystemCallFilters= has been added to services | |
2200 | which may be used to apply blacklists or whitelists to | |
2201 | system calls. This is based on SECCOMP Mode 2 of Linux 3.5. | |
2202 | ||
2203 | * nspawn gained a new --link-journal= switch (and quicker: -j) | |
2204 | to link the container journal with the host. This makes it | |
2205 | very easy to centralize log viewing on the host for all | |
2206 | guests while still keeping the journal files separated. | |
2207 | ||
2208 | * Many bugfixes and optimizations | |

b5b4c94a LP |
2215 | CHANGES WITH 186: |
2216 | ||
2217 | * Several tools now understand kernel command line arguments, | |
2218 | which are only read when run in an initial RAM disk. They | |
2219 | usually follow closely their normal counterparts, but are | |
2220 | prefixed with rd. | |
2221 | ||
2222 | * There's a new tool to analyze the readahead files that are | |
2223 | automatically generated at boot. Use: | |
2224 | ||
2225 | /usr/lib/systemd/systemd-readahead analyze /.readahead | |
2226 | ||
2227 | * We now provide an early debug shell on tty9 if this enabled. Use: | |
2228 | ||
d1f9edaf | 2229 | systemctl enable debug-shell.service |
b5b4c94a LP |
2230 | |
2231 | * All plymouth related units have been moved into the Plymouth | |
2232 | package. Please make sure to upgrade your Plymouth version | |
2233 | as well. | |
2234 | ||
2235 | * systemd-tmpfiles now supports getting passed the basename of | |
2236 | a configuration file only, in which case it will look for it | |
2237 | in all appropriate directories automatically. | |
2238 | ||
2239 | * udevadm info now takes a /dev or /sys path as argument, and | |
2240 | does the right thing. Example: | |
2241 | ||
2242 | udevadm info /dev/sda | |
2243 | udevadm info /sys/class/block/sda | |
2244 | ||
2245 | * systemctl now prints a warning if a unit is stopped but a | |
2246 | unit that might trigger it continues to run. Example: a | |
2247 | service is stopped but the socket that activates it is left | |
2248 | running. | |
2249 | ||
2250 | * "systemctl status" will now mention if the log output was | |
2251 | shortened due to rotation since a service has been started. | |
2252 | ||
2253 | * The journal API now exposes functions to determine the | |
2254 | "cutoff" times due to rotation. | |
2255 | ||
2256 | * journald now understands SIGUSR1 and SIGUSR2 for triggering | |
2257 | immediately flushing of runtime logs to /var if possible, | |
2258 | resp. for triggering immediate rotation of the journal | |
2259 | files. | |
2260 | ||
2261 | * It is now considered an error if a service is attempted to | |
2262 | be stopped that is not loaded. | |
2263 | ||
2264 | * XDG_RUNTIME_DIR now uses numeric UIDs instead of usernames. | |
2265 | ||
2266 | * systemd-analyze now supports Python 3 | |
2267 | ||
2268 | * tmpfiles now supports cleaning up directories via aging | |
2269 | where the first level dirs are always kept around but | |
2270 | directories beneath it automatically aged. This is enabled | |
2271 | by prefixing the age field with '~'. | |
2272 | ||
2273 | * Seat objects now expose CanGraphical, CanTTY properties | |
2274 | which is required to deal with very fast bootups where the | |
2275 | display manager might be running before the graphics drivers | |
2276 | completed initialization. | |
2277 | ||
2278 | * Seat objects now expose a State property. | |
2279 | ||
2280 | * We now include RPM macros for service enabling/disabling | |
2281 | based on the preset logic. We recommend RPM based | |
2282 | distributions to make use of these macros if possible. This | |
2283 | makes it simpler to reuse RPM spec files across | |
2284 | distributions. | |
2285 | ||
2286 | * We now make sure that the collected systemd unit name is | |
2287 | always valid when services log to the journal via | |
2288 | STDOUT/STDERR. | |
2289 | ||
2290 | * There's a new man page kernel-command-line(7) detailing all | |
2291 | command line options we understand. | |
2292 | ||
2293 | * The fstab generator may now be disabled at boot by passing | |
2294 | fstab=0 on the kernel command line. | |
2295 | ||
91ac7425 | 2296 | * A new kernel command line option modules-load= is now understood |
b5b4c94a LP |
2297 | to load a specific kernel module statically, early at boot. |
2298 | ||
2299 | * Unit names specified on the systemctl command line are now | |
2300 | automatically escaped as needed. Also, if file system or | |
2301 | device paths are specified they are automatically turned | |
2302 | into the appropriate mount or device unit names. Example: | |
2303 | ||
2304 | systemctl status /home | |
2305 | systemctl status /dev/sda | |
2306 | ||
2307 | * The SysVConsole= configuration option has been removed from | |
2308 | system.conf parsing. | |
2309 | ||
2310 | * The SysV search path is no longer exported on the D-Bus | |
2311 | Manager object. | |
2312 | ||
2313 | * The Names= option is been removed from unit file parsing. | |
2314 | ||
2315 | * There's a new man page bootup(7) detailing the boot process. | |
2316 | ||
2317 | * Every unit and every generator we ship with systemd now | |
2318 | comes with full documentation. The self-explanatory boot is | |
2319 | complete. | |
2320 | ||
2321 | * A couple of services gained "systemd-" prefixes in their | |
2322 | name if they wrap systemd code, rather than only external | |
2323 | code. Among them fsck@.service which is now | |
2324 | systemd-fsck@.service. | |
2325 | ||
2326 | * The HaveWatchdog property has been removed from the D-Bus | |
2327 | Manager object. | |
2328 | ||
2329 | * systemd.confirm_spawn= on the kernel command line should now | |
2330 | work sensibly. | |
2331 | ||
2332 | * There's a new man page crypttab(5) which details all options | |
2333 | we actually understand. | |
2334 | ||
2335 | * systemd-nspawn gained a new --capability= switch to pass | |
2336 | additional capabilities to the container. | |
2337 | ||
2338 | * timedated will now read known NTP implementation unit names | |
5b00c016 | 2339 | from /usr/lib/systemd/ntp-units.d/*.list, |
b5b4c94a LP |
2340 | systemd-timedated-ntp.target has been removed. |
2341 | ||
2342 | * journalctl gained a new switch "-b" that lists log data of | |
2343 | the current boot only. | |
2344 | ||
2345 | * The notify socket is in the abstract namespace again, in | |
2346 | order to support daemons which chroot() at start-up. | |
2347 | ||
2348 | * There is a new Storage= configuration option for journald | |
2349 | which allows configuration of where log data should go. This | |
2350 | also provides a way to disable journal logging entirely, so | |
2351 | that data collected is only forwarded to the console, the | |
2352 | kernel log buffer or another syslog implementation. | |
2353 | ||
c4f1b862 | 2354 | * Many bugfixes and optimizations |

2367 | ||
b5b4c94a LP |
2368 | * MaxLevelStore=, MaxLevelSyslog=, MaxLevelKMsg=, |
2369 | MaxLevelConsole= can now be specified in | |

2371 | data stored on disk or forwarded by the log level. | |

2382 | * logind is now capable of (optionally) handling power and |
2383 | sleep keys as well as the lid switch. | |
2384 | ||
2385 | * journalctl now understands the syntax "journalctl | |
2386 | /usr/bin/avahi-daemon" to get all log output of a specific | |
2387 | daemon. | |
2388 | ||
2389 | * CapabilityBoundingSet= in system.conf now also influences | |
2390 | the capability bound set of usermode helpers of the kernel. | |

ea5943d3 | 2397 | CHANGES WITH 183: |
b6a86739 | 2398 | |
187076d4 LP |
2399 | * Note that we skipped 139 releases here in order to set the |
2400 | new version to something that is greater than both udev's | |
2401 | and systemd's most recent version number. | |
2402 | ||
194bbe33 KS |
2403 | * udev: all udev sources are merged into the systemd source tree now. |
2404 | All future udev development will happen in the systemd tree. It | |
2405 | is still fully supported to use the udev daemon and tools without | |
2406 | systemd running, like in initramfs or other init systems. Building | |
2407 | udev though, will require the *build* of the systemd tree, but | |
ea5943d3 | 2408 | udev can be properly *run* without systemd. |
07cd4fc1 | 2409 | |
91cf7e5c | 2410 | * udev: /lib/udev/devices/ are not read anymore; systemd-tmpfiles |
f13b388f KS |
2411 | should be used to create dead device nodes as workarounds for broken |
2412 | subsystems. | |
64661ee7 | 2413 | |
2d13da88 KS |
2414 | * udev: RUN+="socket:..." and udev_monitor_new_from_socket() is |
2415 | no longer supported. udev_monitor_new_from_netlink() needs to be | |
2416 | used to subscribe to events. | |
2417 | ||
194bbe33 KS |
2418 | * udev: when udevd is started by systemd, processes which are left |
2419 | behind by forking them off of udev rules, are unconditionally cleaned | |
2420 | up and killed now after the event handling has finished. Services or | |
2421 | daemons must be started as systemd services. Services can be | |
ea5943d3 | 2422 | pulled-in by udev to get started, but they can no longer be directly |
194bbe33 KS |
2423 | forked by udev rules. |
2424 | ||
f13b388f KS |
2425 | * udev: the daemon binary is called systemd-udevd now and installed |
2426 | in /usr/lib/systemd/. Standalone builds or non-systemd systems need | |
2427 | to adapt to that, create symlink, or rename the binary after building | |
2428 | it. | |
2429 | ||
ea5943d3 | 2430 | * libudev no longer provides these symbols: |
c1959569 KS |
2431 | udev_monitor_from_socket() |
2432 | udev_queue_get_failed_list_entry() | |
2433 | udev_get_{dev,sys,run}_path() | |
ea5943d3 | 2434 | The versions number was bumped and symbol versioning introduced. |
c1959569 | 2435 | |
ea5943d3 | 2436 | * systemd-loginctl and systemd-journalctl have been renamed |
9ae9afce | 2437 | to loginctl and journalctl to match systemctl. |
18b754d3 KS |
2438 | |
2439 | * The config files: /etc/systemd/systemd-logind.conf and | |
2440 | /etc/systemd/systemd-journald.conf have been renamed to | |
2441 | logind.conf and journald.conf. Package updates should rename | |
2442 | the files to the new names on upgrade. | |
2443 | ||
ea5943d3 LP |
2444 | * For almost all files the license is now LGPL2.1+, changed |
2445 | from the previous GPL2.0+. Exceptions are some minor stuff | |
2446 | of udev (which will be changed to LGPL2.1 eventually, too), | |
2447 | and the MIT licensed sd-daemon.[ch] library that is suitable | |
2448 | to be used as drop-in files. | |
2449 | ||
2450 | * systemd and logind now handle system sleep states, in | |
49f43d5f | 2451 | particular suspending and hibernating. |
ea5943d3 LP |
2452 | |
2453 | * logind now implements a sleep/shutdown/idle inhibiting logic | |
2454 | suitable for a variety of uses. Soonishly Lennart will blog | |
2455 | about this in more detail. | |
2456 | ||
2457 | * var-run.mount and var-lock.mount are no longer provided | |
2458 | (which prevously bind mounted these directories to their new | |
2459 | places). Distributions which have not converted these | |
2460 | directories to symlinks should consider stealing these files | |
2461 | from git history and add them downstream. | |
2462 | ||
2463 | * We introduced the Documentation= field for units and added | |
2464 | this to all our shipped units. This is useful to make it | |
3943231c | 2465 | easier to explore the boot and the purpose of the various |
ea5943d3 LP |
2466 | units. |
2467 | ||
2468 | * All smaller setup units (such as | |
2469 | systemd-vconsole-setup.service) now detect properly if they | |
2470 | are run in a container and are skipped when | |
2471 | appropriate. This guarantees an entirely noise-free boot in | |
2472 | Linux container environments such as systemd-nspawn. | |
2473 | ||
2474 | * A framework for implementing offline system updates is now | |
2475 | integrated, for details see: | |
2476 | http://freedesktop.org/wiki/Software/systemd/SystemUpdates | |
2477 | ||
2478 | * A new service type Type=idle is available now which helps us | |
2479 | avoiding ugly interleaving of getty output and boot status | |
2480 | messages. | |
2481 | ||
439d6dfd LP |
2482 | * There's now a system-wide CapabilityBoundingSet= option to |
2483 | globally reduce the set of capabilities for the | |
ea5943d3 LP |
2484 | system. This is useful to drop CAP_SYS_MKNOD, CAP_SYS_RAWIO, |
2485 | CAP_NET_RAW, CAP_SYS_MODULE, CAP_SYS_TIME, CAP_SYS_PTRACE or | |
2486 | even CAP_NET_ADMIN system-wide for secure systems. | |
2487 | ||
2488 | * There are now system-wide DefaultLimitXXX= options to | |
2489 | globally change the defaults of the various resource limits | |
2490 | for all units started by PID 1. | |
2491 | ||
2492 | * Harald Hoyer's systemd test suite has been integrated into | |
2493 | systemd which allows easy testing of systemd builds in qemu | |
2494 | and nspawn. (This is really awesome! Ask us for details!) | |
2495 | ||
3943231c LP |
2496 | * The fstab parser is now implemented as generator, not inside |
2497 | of PID 1 anymore. | |
ea5943d3 LP |
2498 | |
2499 | * systemctl will now warn you if .mount units generated from | |
2500 | /etc/fstab are out of date due to changes in fstab that | |
2501 | haven't been read by systemd yet. | |
2502 | ||
2503 | * systemd is now suitable for usage in initrds. Dracut has | |
2504 | already been updated to make use of this. With this in place | |
2505 | initrds get a slight bit faster but primarily are much | |
2506 | easier to introspect and debug since "systemctl status" in | |
2507 | the host system can be used to introspect initrd services, | |
2508 | and the journal from the initrd is kept around too. | |
2509 | ||
2510 | * systemd-delta has been added, a tool to explore differences | |
2511 | between user/admin configuration and vendor defaults. | |
2512 | ||
2513 | * PrivateTmp= now affects both /tmp and /var/tmp. | |
2514 | ||
2515 | * Boot time status messages are now much prettier and feature | |
2516 | proper english language. Booting up systemd has never been | |
2517 | so sexy. | |
2518 | ||
2519 | * Read-ahead pack files now include the inode number of all | |
2520 | files to pre-cache. When the inode changes the pre-caching | |
2521 | is not attempted. This should be nicer to deal with updated | |
2522 | packages which might result in changes of read-ahead | |
2523 | patterns. | |
2524 | ||
2525 | * We now temporaritly lower the kernel's read_ahead_kb variable | |
2526 | when collecting read-ahead data to ensure the kernel's | |
2527 | built-in read-ahead does not add noise to our measurements | |
2528 | of necessary blocks to pre-cache. | |
2529 | ||
2530 | * There's now RequiresMountsFor= to add automatic dependencies | |
2531 | for all mounts necessary for a specific file system path. | |
2532 | ||
2533 | * MountAuto= and SwapAuto= have been removed from | |
2534 | system.conf. Mounting file systems at boot has to take place | |
2535 | in systemd now. | |
2536 | ||
2537 | * nspawn now learned a new switch --uuid= to set the machine | |
2538 | ID on the command line. | |
2539 | ||
f8c0a2cb | 2540 | * nspawn now learned the -b switch to automatically search |
ea5943d3 LP |
2541 | for an init system. |
2542 | ||
2543 | * vt102 is now the default TERM for serial TTYs, upgraded from | |
2544 | vt100. | |
2545 | ||
2546 | * systemd-logind now works on VT-less systems. | |
2547 | ||
2548 | * The build tree has been reorganized. The individual | |
3943231c | 2549 | components now have directories of their own. |
ea5943d3 LP |
2550 | |
2551 | * A new condition type ConditionPathIsReadWrite= is now available. | |
2552 | ||
2553 | * nspawn learned the new -C switch to create cgroups for the | |
2554 | container in other hierarchies. | |
2555 | ||
2556 | * We now have support for hardware watchdogs, configurable in | |
2557 | system.conf. | |
2558 | ||
2559 | * The scheduled shutdown logic now has a public API. | |
2560 | ||
2561 | * We now mount /tmp as tmpfs by default, but this can be | |
2562 | masked and /etc/fstab can override it. | |
2563 | ||
2564 | * Since udisks doesn't make use of /media anymore we are not | |
2565 | mounting a tmpfs on it anymore. | |
2566 | ||
2567 | * journalctl gained a new --local switch to only interleave | |
2568 | locally generated journal files. | |
2569 | ||
2570 | * We can now load the IMA policy at boot automatically. | |
2571 | ||
2572 | * The GTK tools have been split off into a systemd-ui. | |

16f1239e | 2585 | CHANGES WITH 44: |
b6a86739 | 2586 | |
16f1239e LP |
2587 | * This is mostly a bugfix release |
2588 | ||
2589 | * Support optional initialization of the machine ID from the | |
2590 | KVM or container configured UUID. | |
2591 | ||
2592 | * Support immediate reboots with "systemctl reboot -ff" | |
2593 | ||
2594 | * Show /etc/os-release data in systemd-analyze output | |
2595 | ||
ab06eef8 | 2596 | * Many bugfixes for the journal, including endianness fixes and |
16f1239e LP |
2597 | ensuring that disk space enforcement works |
2598 | ||
2599 | * sd-login.h is C++ comptaible again | |
2600 | ||
2601 | * Extend the /etc/os-release format on request of the Debian | |
2602 | folks | |
2603 | ||
2604 | * We now refuse non-UTF8 strings used in various configuration | |
2605 | and unit files. This is done to ensure we don't pass invalid | |
2606 | data over D-Bus or expose it elsewhere. | |
2607 | ||
2608 | * Register Mimo USB Screens as suitable for automatic seat | |
2609 | configuration | |
2610 | ||
2611 | * Read SELinux client context from journal clients in a race | |
2612 | free fashion | |
2613 | ||
2614 | * Reorder configuration file lookup order. /etc now always | |
2615 | overrides /run in order to allow the administrator to always | |
2616 | and unconditionally override vendor supplied or | |
2617 | automatically generated data. | |
2618 | ||
2619 | * The various user visible bits of the journal now have man | |
2620 | pages. We still lack man pages for the journal API calls | |
2621 | however. | |
2622 | ||
2623 | * We now ship all man pages in HTML format again in the | |
2624 | tarball. | |

b6a86739 | 2632 | |
437b7dee LP |
2633 | * This is mostly a bugfix release |
2634 | ||
2635 | * systems lacking /etc/os-release are no longer supported. | |
2636 | ||
2637 | * Various functionality updates to libsystemd-login.so | |
2638 | ||
2639 | * Track class of PAM logins to distuingish greeters from | |
2640 | normal user logins. | |

b6a86739 | 2646 | |
204fa33c LP |
2647 | * This is an important bugfix release for v41. |
2648 | ||
2649 | * Building man pages is now optional which should be useful | |
2650 | for those building systemd from git but unwilling to install | |
2651 | xsltproc. | |
2652 | ||
2653 | * Watchdog support for supervising services is now usable. In | |
2654 | a future release support for hardware watchdogs | |
2655 | (i.e. /dev/watchdog) will be added building on this. | |
2656 | ||
2657 | * Service start rate limiting is now configurable and can be | |
2658 | turned off per service. When a start rate limit is hit a | |
2659 | reboot can automatically be triggered. | |
2660 | ||
2661 | * New CanReboot(), CanPowerOff() bus calls in systemd-logind. | |

e0d25329 | 2667 | CHANGES WITH 41: |
b6a86739 | 2668 | |
e0d25329 KS |
2669 | * The systemd binary is installed /usr/lib/systemd/systemd now; |
2670 | An existing /sbin/init symlink needs to be adapted with the | |
2671 | package update. | |
2672 | ||
b13df964 LP |
2673 | * The code that loads kernel modules has been ported to invoke |
2674 | libkmod directly, instead of modprobe. This means we do not | |
2675 | support systems with module-init-tools anymore. | |
2676 | ||
2677 | * Watchdog support is now already useful, but still not | |
2678 | complete. | |
2679 | ||
2680 | * A new kernel command line option systemd.setenv= is | |
2681 | understood to set system wide environment variables | |
2682 | dynamically at boot. | |
2683 | ||
e9c1ea9d | 2684 | * We now limit the set of capabilities of systemd-journald. |
ccd07a08 | 2685 | |
353e12c2 LP |
2686 | * We now set SIGPIPE to ignore by default, since it only is |
2687 | useful in shell pipelines, and has little use in general | |
2688 | code. This can be disabled with IgnoreSIPIPE=no in unit | |
2689 | files. | |

d26e4270 | 2695 | CHANGES WITH 40: |
b6a86739 | 2696 | |
d26e4270 LP |
2697 | * This is mostly a bugfix release |
2698 | ||
2699 | * We now expose the reason why a service failed in the | |
2700 | "Result" D-Bus property. | |
2701 | ||
2702 | * Rudimentary service watchdog support (will be completed over | |
2703 | the next few releases.) | |
2704 | ||
2705 | * When systemd forks off in order execute some service we will | |
2706 | now immediately changes its argv[0] to reflect which process | |
2707 | it will execute. This is useful to minimize the time window | |
2708 | with a generic argv[0], which makes bootcharts more useful | |

220a21d3 | 2714 | CHANGES WITH 39: |
b6a86739 | 2715 | |
220a21d3 LP |
2716 | * This is mostly a test release, but incorporates many |
2717 | bugfixes. | |
2718 | ||
2719 | * New systemd-cgtop tool to show control groups by their | |
2720 | resource usage. | |
2721 | ||
2722 | * Linking against libacl for ACLs is optional again. If | |
2723 | disabled, support tracking device access for active logins | |
2724 | goes becomes unavailable, and so does access to the user | |
2725 | journals by the respective users. | |
2726 | ||
2727 | * If a group "adm" exists, journal files are automatically | |
2728 | owned by them, thus allow members of this group full access | |
2729 | to the system journal as well as all user journals. | |
2730 | ||
2731 | * The journal now stores the SELinux context of the logging | |
2732 | client for all entries. | |
2733 | ||
2734 | * Add C++ inclusion guards to all public headers | |
2735 | ||
2736 | * New output mode "cat" in the journal to print only text | |
2737 | messages, without any meta data like date or time. | |
2738 | ||
2739 | * Include tiny X server wrapper as a temporary stop-gap to | |
2740 | teach XOrg udev display enumeration. This is used by display | |
2741 | managers such as gdm, and will go away as soon as XOrg | |
2742 | learned native udev hotplugging for display devices. | |
2743 | ||
2744 | * Add new systemd-cat tool for executing arbitrary programs | |
2745 | with STDERR/STDOUT connected to the journal. Can also act as | |
2746 | BSD logger replacement, and does so by default. | |
2747 | ||
2748 | * Optionally store all locally generated coredumps in the | |
2749 | journal along with meta data. | |
2750 | ||
2751 | * systemd-tmpfiles learnt four new commands: n, L, c, b, for | |
2752 | writing short strings to files (for usage for /sys), and for | |
2753 | creating symlinks, character and block device nodes. | |
2754 | ||
2755 | * New unit file option ControlGroupPersistent= to make cgroups | |
2756 | persistent, following the mechanisms outlined in | |
2757 | http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups | |
2758 | ||
2759 | * Support multiple local RTCs in a sane way | |
2760 | ||
2761 | * No longer monopolize IO when replaying readahead data on | |
2762 | rotating disks, since we might starve non-file-system IO to | |
2763 | death, since fanotify() will not see accesses done by blkid, | |
2764 | or fsck. | |
2765 | ||
2766 | * Don't show kernel threads in systemd-cgls anymore, unless | |
2767 | requested with new -k switch. | |

2772 | CHANGES WITH 38: | |
b6a86739 | 2773 | |
220a21d3 LP |
2774 | * This is mostly a test release, but incorporates many |
2775 | bugfixes. | |
2776 | ||
2777 | * The git repository moved to: | |
2778 | git://anongit.freedesktop.org/systemd/systemd | |
2779 | ssh://git.freedesktop.org/git/systemd/systemd | |
2780 | ||
2781 | * First release with the journal | |
2782 | http://0pointer.de/blog/projects/the-journal.html | |
2783 | ||
2784 | * The journal replaces both systemd-kmsg-syslogd and | |
2785 | systemd-stdout-bridge. | |
2786 | ||
2787 | * New sd_pid_get_unit() API call in libsystemd-logind | |
2788 | ||
2789 | * Many systemadm clean-ups | |
2790 | ||
2791 | * Introduce remote-fs-pre.target which is ordered before all | |
2792 | remote mounts and may be used to start services before all | |
2793 | remote mounts. | |
2794 | ||
2795 | * Added Mageia support | |
2796 | ||
2797 | * Add bash completion for systemd-loginctl | |
2798 | ||
2799 | * Actively monitor PID file creation for daemons which exit in | |
2800 | the parent process before having finished writing the PID | |
2801 | file in the daemon process. Daemons which do this need to be | |
2802 | fixed (i.e. PID file creation must have finished before the | |
2803 | parent exits), but we now react a bit more gracefully to them. | |
2804 | ||
2805 | * Add colourful boot output, mimicking the well-known output | |
2806 | of existing distributions. | |
2807 | ||
2808 | * New option PassCredentials= for socket units, for | |
2809 | compatibility with a recent kernel ABI breakage. | |
2810 | ||
2811 | * /etc/rc.local is now hooked in via a generator binary, and | |
2812 | thus will no longer act as synchronization point during | |
2813 | boot. | |
2814 | ||
2815 | * systemctl list-unit-files now supports --root=. | |
2816 | ||
2817 | * systemd-tmpfiles now understands two new commands: z, Z for | |
2818 | relabelling files according to the SELinux database. This is | |
2819 | useful to apply SELinux labels to specific files in /sys, | |
2820 | among other things. | |
2821 | ||
2822 | * Output of SysV services is now forwarded to both the console | |
2823 | and the journal by default, not only just the console. | |
2824 | ||
2825 | * New man pages for all APIs from libsystemd-login. | |
2826 | ||
2827 | * The build tree got reorganized and a the build system is a | |
2828 | lot more modular allowing embedded setups to specifically | |
2829 | select the components of systemd they are interested in. | |
2830 | ||
2831 | * Support for Linux systems lacking the kernel VT subsystem is | |
2832 | restored. | |
2833 | ||
2834 | * configure's --with-rootdir= got renamed to | |
2835 | --with-rootprefix= to follow the naming used by udev and | |
2836 | kmod | |
2837 | ||
2838 | * Unless specified otherwise we'll now install to /usr instead | |
2839 | of /usr/local by default. | |
2840 | ||
2841 | * Processes with '@' in argv[0][0] are now excluded from the | |
2842 | final shut-down killing spree, following the logic explained | |
2843 | in: | |
2844 | http://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons | |
2845 | ||
2846 | * All processes remaining in a service cgroup when we enter | |
2847 | the START or START_PRE states are now killed with | |
2848 | SIGKILL. That means it is no longer possible to spawn | |
2849 | background processes from ExecStart= lines (which was never | |
2850 | supported anyway, and bad style). | |
2851 | ||
2852 | * New PropagateReloadTo=/PropagateReloadFrom= options to bind | |
2853 | reloading of units together. | |
