3 | CHANGES WITH 41: |
4 | * The systemd binary is installed /usr/lib/systemd/systemd now; | |
5 | An existing /sbin/init symlink needs to be adapted with the | |
6 | package update. | |
7 | ||
b13df964 LP |
8 | * The code that loads kernel modules has been ported to invoke |
9 | libkmod directly, instead of modprobe. This means we do not | |
10 | support systems with module-init-tools anymore. | |
11 | ||
12 | * Watchdog support is now already useful, but still not | |
13 | complete. | |
14 | ||
15 | * A new kernel command line option systemd.setenv= is | |
16 | understood to set system wide environment variables | |
17 | dynamically at boot. | |
18 | ||
ccd07a08 LP |
19 | * We now limit the set of capabilities of systemd-journald. |

25 | CHANGES WITH 40: |
26 | * This is mostly a bugfix release | |
27 | ||
28 | * We now expose the reason why a service failed in the | |
29 | "Result" D-Bus property. | |
30 | ||
31 | * Rudimentary service watchdog support (will be completed over | |
32 | the next few releases.) | |
33 | ||
34 | * When systemd forks off in order execute some service we will | |
35 | now immediately changes its argv[0] to reflect which process | |
36 | it will execute. This is useful to minimize the time window | |
37 | with a generic argv[0], which makes bootcharts more useful | |

43 | CHANGES WITH 39: |
44 | * This is mostly a test release, but incorporates many | |
45 | bugfixes. | |
46 | ||
47 | * New systemd-cgtop tool to show control groups by their | |
48 | resource usage. | |
49 | ||
50 | * Linking against libacl for ACLs is optional again. If | |
51 | disabled, support tracking device access for active logins | |
52 | goes becomes unavailable, and so does access to the user | |
53 | journals by the respective users. | |
54 | ||
55 | * If a group "adm" exists, journal files are automatically | |
56 | owned by them, thus allow members of this group full access | |
57 | to the system journal as well as all user journals. | |
58 | ||
59 | * The journal now stores the SELinux context of the logging | |
60 | client for all entries. | |
61 | ||
62 | * Add C++ inclusion guards to all public headers | |
63 | ||
64 | * New output mode "cat" in the journal to print only text | |
65 | messages, without any meta data like date or time. | |
66 | ||
67 | * Include tiny X server wrapper as a temporary stop-gap to | |
68 | teach XOrg udev display enumeration. This is used by display | |
69 | managers such as gdm, and will go away as soon as XOrg | |
70 | learned native udev hotplugging for display devices. | |
71 | ||
72 | * Add new systemd-cat tool for executing arbitrary programs | |
73 | with STDERR/STDOUT connected to the journal. Can also act as | |
74 | BSD logger replacement, and does so by default. | |
75 | ||
76 | * Optionally store all locally generated coredumps in the | |
77 | journal along with meta data. | |
78 | ||
79 | * systemd-tmpfiles learnt four new commands: n, L, c, b, for | |
80 | writing short strings to files (for usage for /sys), and for | |
81 | creating symlinks, character and block device nodes. | |
82 | ||
83 | * New unit file option ControlGroupPersistent= to make cgroups | |
84 | persistent, following the mechanisms outlined in | |
85 | http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups | |
86 | ||
87 | * Support multiple local RTCs in a sane way | |
88 | ||
89 | * No longer monopolize IO when replaying readahead data on | |
90 | rotating disks, since we might starve non-file-system IO to | |
91 | death, since fanotify() will not see accesses done by blkid, | |
92 | or fsck. | |
93 | ||
94 | * Don't show kernel threads in systemd-cgls anymore, unless | |
95 | requested with new -k switch. | |

100 | CHANGES WITH 38: | |
101 | * This is mostly a test release, but incorporates many | |
102 | bugfixes. | |
103 | ||
104 | * The git repository moved to: | |
105 | git://anongit.freedesktop.org/systemd/systemd | |
106 | ssh://git.freedesktop.org/git/systemd/systemd | |
107 | ||
108 | * First release with the journal | |
109 | http://0pointer.de/blog/projects/the-journal.html | |
110 | ||
111 | * The journal replaces both systemd-kmsg-syslogd and | |
112 | systemd-stdout-bridge. | |
113 | ||
114 | * New sd_pid_get_unit() API call in libsystemd-logind | |
115 | ||
116 | * Many systemadm clean-ups | |
117 | ||
118 | * Introduce remote-fs-pre.target which is ordered before all | |
119 | remote mounts and may be used to start services before all | |
120 | remote mounts. | |
121 | ||
122 | * Added Mageia support | |
123 | ||
124 | * Add bash completion for systemd-loginctl | |
125 | ||
126 | * Actively monitor PID file creation for daemons which exit in | |
127 | the parent process before having finished writing the PID | |
128 | file in the daemon process. Daemons which do this need to be | |
129 | fixed (i.e. PID file creation must have finished before the | |
130 | parent exits), but we now react a bit more gracefully to them. | |
131 | ||
132 | * Add colourful boot output, mimicking the well-known output | |
133 | of existing distributions. | |
134 | ||
135 | * New option PassCredentials= for socket units, for | |
136 | compatibility with a recent kernel ABI breakage. | |
137 | ||
138 | * /etc/rc.local is now hooked in via a generator binary, and | |
139 | thus will no longer act as synchronization point during | |
140 | boot. | |
141 | ||
142 | * systemctl list-unit-files now supports --root=. | |
143 | ||
144 | * systemd-tmpfiles now understands two new commands: z, Z for | |
145 | relabelling files according to the SELinux database. This is | |
146 | useful to apply SELinux labels to specific files in /sys, | |
147 | among other things. | |
148 | ||
149 | * Output of SysV services is now forwarded to both the console | |
150 | and the journal by default, not only just the console. | |
151 | ||
152 | * New man pages for all APIs from libsystemd-login. | |
153 | ||
154 | * The build tree got reorganized and a the build system is a | |
155 | lot more modular allowing embedded setups to specifically | |
156 | select the components of systemd they are interested in. | |
157 | ||
158 | * Support for Linux systems lacking the kernel VT subsystem is | |
159 | restored. | |
160 | ||
161 | * configure's --with-rootdir= got renamed to | |
162 | --with-rootprefix= to follow the naming used by udev and | |
163 | kmod | |
164 | ||
165 | * Unless specified otherwise we'll now install to /usr instead | |
166 | of /usr/local by default. | |
167 | ||
168 | * Processes with '@' in argv[0][0] are now excluded from the | |
169 | final shut-down killing spree, following the logic explained | |
170 | in: | |
171 | http://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons | |
172 | ||
173 | * All processes remaining in a service cgroup when we enter | |
174 | the START or START_PRE states are now killed with | |
175 | SIGKILL. That means it is no longer possible to spawn | |
176 | background processes from ExecStart= lines (which was never | |
177 | supported anyway, and bad style). | |
178 | ||
179 | * New PropagateReloadTo=/PropagateReloadFrom= options to bind | |
180 | reloading of units together. | |
