3* Should systemctl status \* work on all unit types, not just .service?
4
f957632b
KS
5* Dangling symlinks of .automount unit files in .wants/ directories, set up
6 automount points even when the original .automount file did not exist
7 anymore. Only the .mount unit was still around.

15* When systemctl --host is used, underlying ssh connection can remain open.
16 bus_close does not kill children?

f38afcd0 18External:
f85857df 19
f38afcd0 20* Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
bafb15ba 21
83a1ff25
ZJS
22* wiki: update journal format documentation for lz4 additions
23
5e524b40
LP
24Janitorial Clean-ups:
25
26* code cleanup: retire FOREACH_WORD_QUOTED, port to extract_first_word() loops instead
27
28* replace manual readdir() loops with FOREACH_DIRENT or FOREACH_DIRENT_ALL
29
30* Get rid of the last strerror() invocations in favour of %m and strerror_r()
31
32* Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
33
fd6c2363 34Features:
47ee3ee0 35
bd098bce
LP
36* PID1: find a way how we can reload unit file configuration for
37 specific units only, without reloading the whole of systemd
38
de7399eb
LP
39* add an explicit parser for LimitNICE= and LimitRTPRIO= that verifies
40 the specified range and generates sane error messages for incorrect
41 specifications. Also, for LimitNICE= maybe introduce a syntax such
42 as "+5" or "-7" in order to make the limits more readable as they
43 are otherwise shifted by 20.
44
0d4c4b71
LP
45* do something about "/control" subcgroups in the unified cgroup hierarchy
46
3efc8c72
LP
47* when we detect that there are waiting jobs but no running jobs, do something
48
06ce859b 49* push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
03364e47 50
42718282 51* add a concept of RemainAfterExit= to scope units
03364e47
LP
52
53* add a new command "systemctl revert" or so, that removes all dropin
54 snippets in /run and /etc, and all unit files with counterparts in
55 /usr, and thus undoes what "systemctl set-property" and "systemctl
56 edit" create. Maybe even add "systemctl revert -a" to do this for
57 all units.
57383116 58
abab5008
LP
59* sd-event: maybe add support for inotify events
60
e6a26d8c
LP
61* PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
62
63* nspawn should send out sd_notify("WATCHDOG=1") messages
64
65* nspawn should optionally support receiving WATCHDOG=1 messages from its payload PID 1...
66
13612050
LP
67* consider throwing a warning if a service declares it wants to be "Before=" a .device unit.
68
a2088fd0
LP
69* "systemctl edit" should know a mode to create a new unit file
70
71* there's probably something wrong with having user mounts below /sys,
72 as we have for debugfs. for exmaple, src/core/mount.c handles mounts
73 prefixed with /sys generally special.
74 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
75
affb71da
LP
76* nspawn: fix logic always print a final newline on output.
77 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
78
eedb4ac8
LP
79* man: document that unless you use StandardError=null the shell >/dev/stderr won't work in shell scripts in services
80
203e81db
LP
81* "systemctl daemon-reload" should result in /etc/systemd/system.conf being reloaded by systemd
82
63432f5d
LP
83* install: include generator dirs in unit file search paths
84
fd6c2363 85* logind: follow PropertiesChanged state more closely, to deal with quick logouts and relogins
47ee3ee0 86
c2570ab9
LP
87* invent a better systemd-run scheme for naming scopes, that works with remoting
88
89* add journalctl -H that talks via ssh to a remote peer and passes through binary logs data
90
eba6fd30
ZJS
91* change journalctl -M to acquire fd to journal directory via machined, and then operate on that via openat() instead of absolute paths
92
93* add a version of --merge which also merges /var/log/journal/remote
c2570ab9
LP
94
95* log accumulated resource usage after each service invocation
96
d89e6475
LP
97* nspawn: a nice way to boot up without machine id set, so that it is set at boot automatically for supporting --ephemeral. Maybe hash the host machine id together with the machine name to generate the machine id for the container
98
e7e90a8e
LP
99* logind: rename session scope so that it includes the UID. THat way
100 the session scope can be arranged freely in slices and we don't have
101 make assumptions about their slice anymore.
f06944d6 102
d72bc597
LP
103* journalctl: -m should access container journals directly by enumerating them via machined, and also watch containers coming and going. Benefit: nspawn --ephemeral would start working nicely with the journal.
104
105* nspawn: don't copy /etc/resolv.conf from host into container unless we are in shared-network mode
106
107* nspawn: optionally automatically add FORWARD rules to iptables whenever nspawn is running, remove them when shut down.
108
109* importd: generate a nice warning if mkfs.btrfs is missing
110
07cc65c7
LP
111* nspawn: add a logic for cleaning up read-only, hidden container images in /var/lib/machines that are not ancestors of any non-hidden containers
112
113* nspawn: Improve error message when --bind= is used on a non-existing source directory
114
115* nspawn: maybe make copying of /etc/resolv.conf optional, and skip it if --read-only is used
116
117* man: document how update dkr images works with machinectl
118 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028630.html
119
c2570ab9 120* nspawn: as soon as networkd has a bus interface, hook up --network-interface=, --network-bridge= with networkd, to trigger netdev creation should an interface be missing
0a021578 121
dcd12626
LP
122* rework C11 utf8.[ch] to use char32_t instead of uint32_t when referring
123 to unicode chars, to make things more expressive.
124
17978b17
LP
125* "machinectl migrate" or similar to copy a container from or to a
126 difference host, via ssh
127
48e6d6a6
LP
128* tmpfiles: creating new directories/subvolumes/fifos/device nodes
129 should not follow symlinks. None of the other adjustment or creation
130 calls follow symlinks.
131
8aa20381
LP
132* fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
133
b18d23d7
LP
134* docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
135
449a22a5
LP
136* mounting and unmounting mount points manually with different source
137 devices will result in collected collected on all devices used.
138 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030225.html
139
60d17b74
LP
140* add a job mode that will fail if a transaction would mean stopping
141 running units. Use this in timedated to manage the NTP service
142 state.
143 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
144
2f653bde
LP
145* Maybe add support for the equivalent of "ethtool advertise" to .link files?
146 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
147
ac749874
LP
148* .timer units should optionally support CLOCK_BOOTTIME in addition to CLOCK_MONOTONIC
149
e342b744
ZJS
150* When logging about multiple units (stopping BoundTo units, conflicts, etc.),
151 log both units as UNIT=, so that journalctl -u triggers on both.
152
036a4773
LP
153* to allow "linking" of nspawn containers, extend --network-bridge= so
154 that it can dynamically create bridge interfaces that are refcounted
155 by the containers on them. For each group of containers to link together
156
a88abde7
LP
157* journalctl --verify: don't show files that are currently being
158 written to as FAIL, but instead show that their are being written
159 to.
160
f93b36af
LP
161* assign MESSAGE_ID to log messages about failed services
162
20760dcf
LP
163* coredump: make the handler check /proc/$PID/rlimits for RLIMIT_CORE,
164 and supress coredump if turned off. Then change RLIMIT_CORE to
165 infinity by default for all services. This then allows per-service
166 control of coredumping.
167
df22b0bb
LP
168* generate better errors when people try to set transient properties
169 that are not supported...
170 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
171
73cb7754
LP
172* maybe introduce WantsMountsFor=? Usecase:
173 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
174
477e75ef
LP
175* The udev blkid built-in should expose a property that reflects
176 whether media was sensed in USB CF/SD card readers. This should then
177 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
178 picked up by systemd unless they contain a medium. This would mirror
179 the behaviour we already have for CD drives.
180
7dfb0404
LP
181* nspawn: emulate /dev/kmsg using CUSE and turn off the syslog syscall
182 with seccomp. That should provide us with a useful log buffer that
183 systemd can log to during early boot, and disconnect container logs
184 from the kernel's logs.
185
2bc39683
LP
186* networkd/udev: implement SR_IOV configuration in .link files:
187 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
188
63b20d5c
MS
189* Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
190 services that run under their own user ids, and use User= (but only
191 in a world where userns is ubiquitous since otherwise we cannot
192 invoke those daemons on the host AND in a container anymore). Also,
193 if LimitNPROC= is used without User= we should warn and refuse
194 operation.
687f6a0b 195
31a11e8f
LP
196* logind: maybe allow configuration of the StopTimeout for session scopes
197
41bc22f3 198* Set NoNewPrivileges= on all of our own services, where that makes sense
dbdee28b 199
17fe5614
LP
200* Rework systemctl's GetAll property parsing to use the generic bus_map_all_properties() API
201
202* rework journald sigbus stuff to use mutex
203
7687f85e
LP
204* import-dkr: support tarsum checksum verification, if it becomes reality one day...
205
206* import-dkr: convert json bits to nspawn configuration
207
c14db9b3
LP
208* core/cgroup: support net_cls modules, and support automatically allocating class ids, then add support for making firewall changes depending on it, to implement a per-service firewall
209
fa607802
LP
210* introduce systemd-nspawn-ephemeral@.service, and hook it into "machinectl start" with a new --ephemeral switch
211
fa607802 212* "machinectl status" should also show internal logs of the container in question
a47e6701 213
92ff080b 214* "machinectl list-images" should show os-release data, as well as machine-info data (including deployment level)
b80c66ba 215
c3a0d00d
LP
216* Port various tools to make use of verbs.[ch], where applicable
217
c3a0d00d
LP
218* "machinectl history"
219
220* "machinectl diff"
221
de146bb2
LP
222* "machinectl commit" that takes a writable snapshot of a tree, invokes a shell in it, and marks it read-only after use
223
de146bb2
LP
224* systemd-nspawn -x should support ephemeral instances of gpt images
225
c3a0d00d
LP
226* hostnamectl: show root image uuid
227
82e6c50c
LP
228* sysfs set api in libudev is not const
229
d2f81fb0
LP
230* Find a solution for SMACK capabilities stuff:
231 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
98cd2651 232
2a441c8a
LP
233* "systemctl preset-all" should probably order the unit files it
234 operates on lexicographically before starting to work, in order to
235 ensure deterministic behaviour if two unit files conflict (like DMs
236 do, for example)
237
40ff4a4a
LP
238* resolved should optionally register additional per-interface LLMNR
239 names, so that for the container case we can establish the same name
240 (maybe "host") for referencing the server, everywhere.
241
0a86c1a9
LP
242* systemd-journal-upload (or a new, related tool): allow pushing out
243 journal messages onto the network in BSD syslog protocol,
f131770b 244 continuously. Default to some link-local IP mcast group, to make this
0a86c1a9
LP
245 useful as a one-stop debugging tool.
246
247* synchronize console access with BSD locks:
248 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
249
250* as soon as we have kdbus, and sender timestamps, revisit coalescing multiple parallel daemon reloads:
251 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
252
e3286870
LP
253* the install state probably shouldn't get confused by generated units, think dbus1/kdbus compat!
254
e3286870
LP
255* in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
256
8514b677
LP
257* figure out when we can use the coarse timers
258
7b0fce61
LP
259* add "systemctl start -v foobar.service" that shows logs of a service
260 while the start command runs. This is non-trivial to do without
261 races though, since we should flush out all journal messages before
262 returning from the "systemctl stop".
263
b568ef14 264* firstboot: make it useful to be run immediately after yum --installroot to set up a machine. (most specifically, make --copy-root-password work even if /etc/passwd already exists
c2d5b3c9 265
264b8070
LP
266* timesyncd + resolved: add ugly bus calls to set NTP and DNS servers per-interface, for usage by NM
267
7e27f312
LP
268* add infrastructure to allocate dynamic/transient users and UID ranges, for use in user-namespaced containers, per-seat gdm login screens and gdm guest sessions
269
f81e67f7
LP
270* machined: add an API so that libvirt-lxc can inform us about network interfaces being removed or added to an existing machine
271
d48b7bd2
LP
272* maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
273
758c4d7a
LP
274* introduce systemd-timesync-wait.service or so to sync on an NTP fix?
275
821cc13d
LP
276* systemd --user should issue sd_notify() upon reaching basic.target, not on becoming idle
277
8483d73f
LP
278* consider showing the unit names during boot up in the status output, not just the unit descriptions
279
8483d73f
LP
280* dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
281
282* maybe allow timer units with an empty Units= setting, so that they
283 can be used for resuming the system but nothing else.
284
25e773ee 285* what to do about udev db binary stability for apps? (raw access is not an option)
b857e042 286
6dab5bb1
LP
287* maybe provide an API to allow migration of foreign PIDs into existing scopes.
288
384a4be2
LP
289* maybe support a new very "soft" reboot mode, that simply kills all processes, disassembles everything, flushes /run and sysvipc, and then reexecs systemd again
290
706d9750
LP
291* man: document that corrupted journal files is nothing to act on
292
3bcde97e
LP
293* man: maybe use the word "inspect" rather than "introspect"?
294
533bb267
LP
295* "machinectl list" should probably show columns for OS version and IP addresses
296
279f0366 297* systemctl: if some operation fails, show log output?
533bb267 298
b42de08a
ZJS
299* systemctl edit:
300- allow creation of units from scratch
301- use equvalent of cat() to insert existing config as a comment, prepended with #.
302 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
202aea45 303
42aeb14a
LP
304* refcounting in sd-resolve is borked
305
306* exponential backoff in timesyncd and resolved when we cannot reach a server
307
68685607 308* extract_many_words() should probably be used by a lot of code that
14a32924
LP
309 currently uses FOREACH_WORD and friends. For example, most conf
310 parsing callbacks should use it.
311
563b1bdc
LP
312* merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
313
5dcf9838
LP
314* systemd.show_status= should probably have a mode where only failed
315 units are shown.
316
6bd7941e
TG
317* add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
318 (throughout the codebase, not only PID1)
319
b873d33e 320* networkd:
d61bb44a 321 - add LLDP client side support
ed220efd
LP
322 - the DHCP lease data (such as NTP/DNS) is still made available when
323 a carrier is lost on a link. It should be removed instantly.
41488fe9
LP
324 - expose in the API the following bits:
325 - option 15, domain name and/or option 119, search list
326 - option 12, host name and/or option 81, fqdn
41488fe9
LP
327 - option 123, 144, geolocation
328 - option 252, configure http proxy (PAC/wpad)
1dbe0a6e
LP
329 - provide a way to define a per-network interface default metric value
330 for all routes to it. possibly a second default for DHCP routes.
157a180e
TG
331 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
332 support Name=foo*|bar*|baz ?
823f4a91 333 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
510cc5ae 334 - allow DUID/IAID to be customized, see issue #394.
b47c7888 335 - support configuration option for TSO (tcp segmentation offload)
d56cc298 336 - networkd: whenever uplink info changes, make DHCP server send out FORCERENEW
b873d33e 337
9d6db739 338* resolved:
1dbe0a6e
LP
339 - put networkd events and rtnl events at a higher priority, so that
340 we always process them before we process client requests
9d6db739 341 - DNSSEC
ff3d6560 342 - add display of private key types (http://tools.ietf.org/html/rfc4034#appendix-A.1.1)?
23c4091d
LP
343 - DNS
344 - search paths
9d6db739 345 - mDNS/DNS-SD
0f47ed0a 346 - avahi compat
9d6db739 347 - DNS-SD service registration from socket units
bc075489 348 - edns0
17018c3c
TG
349 - dname: Not necessary for plain DNS as synthesized cname is handed out instead if we do not
350 announce dname support. However, for DNSSEC it is necessary as the synthesized cname
351 will not be signed.
b6b63571 352 - cname on PTR (?)
3f77a1b1 353
e2a69298
LP
354* Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
355
2834ffe7
LP
356* Add a new verb "systemctl top"
357
a940778f
LP
358* add new gpt type for btrfs volumes
359
a01647e5 360* support empty /etc boots nicely:
3c779fa5 361 - nspawn/gpt-generator: introduce new gpt partition type for /usr
a940778f 362 - fstab-generator: support systemd.volatile=yes|no|state on the kernel cmdline, too, similar to nspawn's --volatile=
a01647e5 363
3de03738
LP
364* generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
365
2b1c3767
LP
366* timer units: actually add extra delays to timer units with high AccuracySec values, don't start them already when we are awake...
367
37efac5d
LP
368* a way for container managers to turn off getty starting via $container_headless= or so...
369
7348b3ad
LP
370* figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
371
e107ed18
LP
372* mount_cgroup_controllers(): symlinks need to get the label applied
373
81429136
KS
374* For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
375 they run added to the initial transaction and thus confuse Type=idle.
e107ed18 376
f598ac3e 377* Run most system services with cgroupfs read-only and procfs with a more secure mode (doesn't work, since the hidepid= option is per-pid-namespace, not per-mount)
11fb37f1 378
01083ad0
LP
379* sd-event: generate a failure of a default event loop is executed out-of-thread
380
edb2935c
LP
381* add bus api to query unit file's X fields.
382
769918ec
LP
383* consider adding RuntimeDirectoryUser= + RuntimeDirectoryGroup=
384
385* sd-event: define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
386
6a3f892a 387* gpt-auto-generator:
2a781fc9
LP
388 - Support LUKS for root devices
389 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
6a3f892a 390 - Make /home automount rather than mount?
6a3f892a 391
65026403
LP
392* add generator that pulls in systemd-network from containers when
393 CAP_NET_ADMIN is set, more than the loopback device is defined, even
394 when it is otherwise off
f8901862 395
eda8f067
LP
396* MessageQueueMessageSize= and RLimitFSIZE= (and suchlike) should use parse_iec_size().
397
d4fdc205
LP
398* "busctl status" works only as root on dbus1, since we cannot read
399 /proc/$PID/exe
400
af1082b0
LP
401* implement Distribute= in socket units to allow running multiple
402 service instances processing the listening socket, and open this up
403 for ReusePort=
404
488ad3b3
LP
405* socket units: support creating sockets in different namespace,
406 opening it up for JoinsNamespaceOf=. This would require to fork off
407 a tiny process that joins the namespace and creates/binds the socket
408 and passes this back to PID1 via SCM_RIGHTS. This also could be used
409 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
410
47c94a96
LP
411* New service property: maximum CPU and wallclock runtime for a service
412
09ecd746
LP
413* introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
414 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
415 should SIGSTOP all unit processes in a loop until all processes of
416 it are fully stopped. This can later be used for app management by
417 desktop UIs such as gnome-shell to freeze apps that are not visible
418 on screen, not unlike how job control works on the shell
419
f38afcd0 420* cgroups:
f38afcd0
LP
421 - implement per-slice CPUFairScheduling=1 switch
422 - handle jointly mounted controllers correctly
423 - introduce high-level settings for RT budget, swappiness
424 - how to reset dynamically changed unit cgroup attributes sanely?
425 - when reloading configuration, apply new cgroup configuration
426 - when recursively showing the cgroup hierarchy, optionally also show
427 the hierarchies of child processes
0bee65f0 428
f38afcd0 429* transient units:
f38afcd0
LP
430 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
431 - ensure scope units may be started only a single time
ebcf1f97 432
47c94a96
LP
433* Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
434
718db961
LP
435* when we detect low battery and no AC on boot, show pretty splash and refuse boot
436
f38afcd0 437* machined, localed: when we try to kill an empty cgroup, generate an ESRCH error over the bus
718db961
LP
438
439* libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
440
966204e0
LP
441* be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
442
94676f3e 443* unify dispatch table in systemctl_main() and friends
6fd4d020 444
41644622
LP
445* rfkill,backlight: we probably should run the load tools inside of the udev rules so that the state is properly initialized by the time other software sees it
446
7f79cd71 447* After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
0aafd43d 448
19aadacf
JE
449* If we try to find a unit via a dangling symlink, generate a clean
450 error. Currently, we just ignore it and read the unit from the search
df5f6971
LP
451 path anyway.
452
fcba531e
LP
453* refuse boot if /etc/os-release is missing or /etc/machine-id cannot be set up
454
6aaa8c2f 455* btrfs raid assembly: some .device jobs stay stuck in the queue
c3bb87db 456
d28315e4 457* make sure gdm does not use multi-user-x but the new default X configuration file, and then remove multi-user-x from systemd
18d4e7c2 458
bdeeb6b5
LP
459* man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
460
461* load .d/*.conf dropins for device units
462
4e09014d
LP
463* allow implementation of InaccessibleDirectories=/ plus
464 ReadOnlyDirectories=... for whitelisting files for a service.
465
6bb648a1 466* sd-bus:
0d43ffef 467 - EBADSLT handling
fa607802 468 - GetAllProperties() on a non-existing object does not result in a failure currently
d0928791 469 - kdbus: process fd=-1 for incoming msgs
7212c608 470 - port to sd-resolve for connecting to TCP dbus servers
1f140dd8 471 - kdbus: maybe add controlling tty metadata fields
57f2a947 472 - see if we can introduce a new sd_bus_get_owner_machine_id() call to retrieve the machine ID of the machine of the bus itself
d28315e4 473 - when kdbus does not take our message without memfds, try again with memfds
f38afcd0 474 - see if we can drop more message validation on the sending side
f38afcd0 475 - add API to clone sd_bus_message objects
dc17bcef 476 - make AddMatch calls on dbus1 transports async?
80caea6c 477 - kdbus: matches against source or destination pids for an "strace -p"-like feel. Problem: The PID info needs to be available in userspace too...
ab9716c2 478 - longer term: priority inheritance
df98a87b
LP
479 - dbus spec updates:
480 - kdbus mapping
481 - NameLost/NameAcquired obsolete
482 - GVariant
2ecfc64e 483 - path escaping
6a8b5fa4 484 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
69727e6d 485 - test bloom filter generation indexes
279f0366
LP
486 - bus-proxy: when passing messages from kdbus, make sure we properly
487 handle the case where a large number of fds is appended that we
488 cannot pass into sendmsg() of the AF_UNIX sokcet (which only accepts
489 253 messages)
b568ef14 490 - kdbus: introduce a concept of "send-only" connections
0ad68f87 491 - kdbus: add counter for refused unicast messages that is passed out via the RECV ioctl. SImilar to the counter for dropped multicast messages we already have.
f38afcd0
LP
492
493* sd-event
12179984 494 - allow multiple signal handlers per signal?
0536ce5d 495 - document chaining of signal handler for SIGCHLD and child handlers
eb01ba5d 496
154ff088
LP
497* in the final killing spree, detect processes from the root directory, and
498 complain loudly if they have argv[0][0] == '@' set.
499 https://bugzilla.redhat.com/show_bug.cgi?id=961044
500
69af4503 501* investigate endianness issues of UUID vs. GUID
e8a7a315 502
461bd8e4
LP
503* dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
504 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
505
ab8e074c
LP
506* add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
507
508* add a pam module that on password changes updates any LUKS slot where the password matches
509
b454b112
LP
510* maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
511
4ff49cb6
LP
512* cgtop: make cgtop useful in a container
513
fff87a35
ZJS
514* test/:
515 - add 'set -e' to scripts in test/
516 - make stuff in test/ work with separate output dir
b8b4d3dd 517
b5c03638 518* seems that when we follow symlinks to units we prefer the symlink
d28315e4 519 destination path over /etc and /usr. We should not do that. Instead
b5c03638
LP
520 /etc should always override /run+/usr and also any symlink
521 destination.
522
eece8c6f
LP
523* when isolating, try to figure out a way how we implicitly can order
524 all units we stop before the isolating unit...
525
356ce991
LP
526* teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
527
c1446921
LP
528* BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
529 that the boot loader should be installed to the ESP. Define a way
530 how an installer can figure out whether a BLS compliant boot loader
531 is installed.
795607b2 532
0be8342c
LP
533* think about requeuing jobs when daemon-reload is issued? usecase:
534 the initrd issues a reload after fstab from the host is accessible
535 and we might want to requeue the mounts local-fs acquired through
536 that automatically.
537
e5ec62c5 538* systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
54c31a79 539
826872b6
LP
540* journal-or-kmsg is currently broken? See reverted commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
541
d28315e4 542* remove any syslog support from log.c -- we probably cannot do this before split-off udev is gone for good
826872b6 543
3679d112
LP
544* shutdown logging: store to EFI var, and store to USB stick?
545
3679d112
LP
546* write UI tool that pops up emergency messages from the journal as notification
547
548* think about window-manager-run-as-user-service problem: exit 0 → activate shutdown.target; exit != 0 → restart service
549
356ce991 550* merge unit_kill_common() and unit_kill_context()
490b7e47 551
81d112a8 552* introduce ExecCondition= in services
490b7e47 553
b44be3ec 554* EFI:
b44be3ec
LP
555 - honor language efi variables for default language selection (if there are any?)
556 - honor timezone efi variables for default timezone selection (if there are any?)
466784c8 557 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
e4181484 558
c0fe5db5 559* maybe do not install getty@tty1.service symlink in /etc but in /usr?
e9fd44b7 560
b44be3ec 561* print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
8ed20651 562
b44be3ec 563* mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
e6c6e7af 564
b44be3ec
LP
565* logind:
566 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
567 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
568 - logind: wakelock/opportunistic suspend support
569 - Add pretty name for seats in logind
570 - logind: allow showing logout dialog from system?
e5ec62c5 571 - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
f38afcd0
LP
572 - session scopes/user unit: add RequiresMountsFor for the home directory of the user
573 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
574 - if pam_systemd is invoked by su from a process that is outside of a
575 any session we should probably just become a NOP, since that's
576 usually not a real user session but just some system code that just
577 needs setuid().
279f0366
LP
578 - logind: make the Suspend()/Hibernate() bus calls wait for the for
579 the job to be completed. before returning, so that clients can wait
580 for "systemctl suspend" to finish to know when the suspending is
581 complete.
582 - logind: when the power button is pressed short, just popup a
583 logout dialog. If it is pressed for 1s, do the usual
584 shutdown. Inspiration are Macs here.
279f0366
LP
585 - expose "Locked" property on logind sesison objects
586 - given that logind now lets PID 1 do all nasty work, we can
587 probably reduce the capability set it retains substantially.
588 (we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
b568ef14 589 - expose orientation sensors and tablet mode through logind
e673ad04 590
b44be3ec 591* exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
e673ad04 592
b44be3ec 593* service: watchdog logic: for testing purposes allow ping, but do not require pong
e673ad04 594
b44be3ec 595* journal:
57f2a947 596 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
c06bf414 597 - import and delete pstore filesystem content at startup
b44be3ec
LP
598 - journald: also get thread ID from client, plus thread name
599 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
600 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
d28315e4 601 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
b44be3ec 602 - declare the local journal protocol stable in the wiki interface chart
b44be3ec
LP
603 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
604 - journald: when dropping msgs due to ratelimit make sure to write
605 "dropped %u messages" not only when we are about to print the next
606 message that works, but alraedy after a short tiemout
607 - check if we can make journalctl by default use --follow mode inside of less if called without args?
608 - maybe add API to send pairs of iovecs via sd_journal_send
609 - journal: when writing journal auto-rotate if time jumps backwards
f47ec8eb 610 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
b44be3ec
LP
611 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
612 and !FOOBAR for events without FOOBAR.
038cf334
ZJS
613 - journal: store timestamp of journal_file_set_offline() int he header,
614 so it is possible to display when the file was last synced.
b44be3ec
LP
615 - journal-send.c, log.c: when the log socket is clogged, and we drop, count this and write a message about this when it gets unclogged again.
616 - journal: find a way to allow dropping history early, based on priority, other rules
617 - journal: When used on NFS, check payload hashes
b44be3ec
LP
618 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
619 - refuse taking lower-case variable names in sd_journal_send() and friends.
620 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
621 - journal: deal nicely with byte-by-byte copied files, especially regards header
b44be3ec 622 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
601d9d6f 623 - Replace utmp, wtmp, btmp, and lastlog completely with journal
f38afcd0 624 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
f38afcd0
LP
625 - when a kernel driver logs in a tight loop, we should ratelimit that too.
626 - journald: optionally, log debug messages to /run but everything else to /var
627 - journald: when we drop syslog messages because the syslog socket is
628 full, make sure to write how many messages are lost as first thing
629 to syslog when it works again.
630 - journald: make sure ratelimit is actually really per-service with the new cgroup changes
631 - change systemd-journal-flush into a service that stays around during
632 boot, and causes the journal to be moved back to /run on shutdown,
d28315e4 633 so that we do not keep /var busy. This needs to happen synchronously,
f38afcd0 634 hence doing this via signals is not going to work.
279f0366
LP
635 - optionally support running journald from the command line for testing purposes in external projects
636 - journald: allow per-priority and per-service retention times when rotating/vacuuming
637 - journald: make use of uid-range.h to managed uid ranges to split
638 journals in.
639 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
640 - improve journalctl performance by loading journal files
641 lazily. Encode just enough information in the file name, so that we
642 do not have to open it to know that it is not interesting for us, for
643 the most common operations.
b44be3ec
LP
644
645* document:
8b8f2591 646 - document that deps in [Unit] sections ignore Alias= fields in
b44be3ec
LP
647 [Install] units of other units, unless those units are disabled
648 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
b44be3ec 649 - document the exit codes when services fail before they are exec()ed
b44be3ec 650 - document that service reload may be implemented as service reexec
eb124a97 651 - document in wiki how to map ical recurrence events to systemd timer unit calendar specifications
f38afcd0
LP
652 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
653 - document systemd-journal-flush.service properly
f38afcd0
LP
654 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
655 - man: document the very specific env the shutdown drop-in tools live in
f38afcd0
LP
656 - man: add more examples to man pages
657 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
b44be3ec
LP
658
659* systemctl:
660 - systemctl list-jobs - show dependencies
661 - add systemctl switch to dump transaction without executing it
662 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
663 - "systemctl disable" on a static unit prints no message and does
664 nothing. "systemctl enable" does nothing, and gives a bad message
665 about it. Should fix both to print nice actionable messages.
666 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
667 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
d28315e4 668 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
b44be3ec 669 - systemctl: "Journal has been rotated since unit was started." message is misleading
f38afcd0
LP
670 - better error message if you run systemctl without systemd running
671 - systemctl status output should should include list of triggering units and their status
f38afcd0
LP
672
673* unit install:
674 - "systemctl mask" should find all names by which a unit is accessible
675 (i.e. by scanning for symlinks to it) and link them all to /dev/null
f38afcd0 676 - systemctl list-unit-files should list generated files (and probably with a new state "generated" for them, or so)
8b04b925 677
b44be3ec 678* timer units:
b44be3ec
LP
679 - timer units should get the ability to trigger when:
680 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
681 o DST changes
eb124a97 682 - Support 2012-02~4 as syntax for specifying the fourth to last day of the month.
f38afcd0 683 - calendarspec: support value ranges with ".." notation. Example: 2013-4..8-1
90e071d1 684 - Modulate timer frequency based on battery state
d2e83c23 685
a19554ed
LP
686* add libsystemd-password or so to query passwords during boot using the password agent logic
687
1cb88f2c
LP
688* If we show an error about a unit (such as not showing up) and it has no Description string, then show a description string generated form the reverse of unit_name_mangle().
689
a7a3f28b
LP
690* clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
691
b44be3ec 692* on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
08f95888 693
9ee58bdd
KS
694* make repeated alt-ctrl-del presses printing a dump, or even force a reboot without
695 waiting for the timeout
dcfc4b2e 696
71ef24d0
LP
697* hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
698
d28315e4 699* currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
1b89884b 700
b44be3ec 701* nspawn:
9cb74bcb 702 - refuses to boot containers without /etc/machine-id (OK?), and with empty /etc/machine-id (not OK).
b44be3ec
LP
703
704* cryptsetup:
b44be3ec
LP
705 - cryptsetup-generator: allow specification of passwords in crypttab itself
706 - move cryptsetup key caching into kernel keyctl?
707 https://bugs.freedesktop.org/show_bug.cgi?id=54982
5f1dac6b 708 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
f8019684 709
424a19f8 710* hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
41f9172f 711 https://bugs.freedesktop.org/show_bug.cgi?id=54712
424a19f8
LP
712
713* after deserializing sockets in socket.c we should reapply sockopts and things

a1cccad1 715* make timer units go away after they elapsed
8556879e 716
4a30847b

719* create /sbin/init symlinks from the build system
720
38a60d71
LP
721* allow writing multiple conditions in unit files on one line

68f16003 723* MountFlags=shared acts as MountFlags=slave right now.
0790b9fe 724
68f16003
LP
725* drop PID 1 reloading, only do reexecing (difficult: Reload()
726 currently is properly synchronous, Reexec() is weird, because we
d28315e4 727 cannot delay the response properly until we are back, so instead of
68f16003 728 being properly synchronous we just keep open the fd and close it
d28315e4 729 when done. That means clients do not get a successful method reply,
68f16003 730 but much rather a disconnect on success.
0790b9fe 731
fd4d89b2
LP
732* properly handle loop back mounts via fstab, especially regards to fsck/passno
