5* Many manager configuration settings that are only applicable to user
6 manager or system manager can be always set. It would be better to reject
7 them when parsing config.

5e524b40
LP
19* Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
20
bb527e11
LP
21* rework mount.c and swap.c to follow proper state enumeration/deserialization
22 semantics, like we do for device.c now

c6407108
LP
24Features:
25
d7b659ef
LP
26* when we fork off generators and such, lower LIMIT_NOFILE soft limit to 1K
27
06bd149a
LP
28* add a concept for automatically loading per-unit secrets off disk and
29 inserting them into the kernel keyring. Maybe SecretsDirectory= similar to
30 ConfigurationDirectory=.
31
d49881a0
LP
32* systemd-gpt-auto: if we find the root dir mounted read-only and the gpt flag
33 doesn't say so generate job that remounts it writable
34
8a7cf157
LP
35* when no locale is configured, default to UEFI's PlatformLang variable
36
bc137cf4
LP
37* When logind.conf contains HandleLidSwitch=suspend-then-hibernate and we can't
38 hibernate because the swap partition isn't large enough, still suspend
39
d3584ec4
LP
40* bootctl: implement Type #2 boot loader entry discovery
41
42* bootctl,sd-boot: actually honour the "architecture" key
43
fe1bff15
LP
44* when a socket unit is spawned with an AF_UNIX path in /var/run, complain and
45 patch it to use /run instead
46
876449bb
LP
47* consider splitting out all temporary file creation APIs (we have so many in
48 fileio.h and elsewhere!) into a new util file of its own.
49
f5435340 50* set memory.oom.group in cgroupsv2 for all leaf cgroups (kernel v4.19+)
32875617 51
06898123
LP
52* drop umask() calls and suchlike from our generators, pid1 should set things up correctly anyway
53
54* paranoia: whenever we process passwords, call mlock() on the memory
55 first. i.e. look for all places we use string_erase()/string_free_erase() and
56 augment them with mlock()
57
32875617
LP
58* whenever oom_kill memory.event event is triggered print a nice log message
59
60* Move RestrictAddressFamily= to the new cgroup create socket
61
62* support the bind/connect/sendmsg cgroup stuff for sandboxing, and possibly
63 patching around
64
76853293
LP
65* maybe implicitly attach monotonic+realtime timestamps to outgoing messages in
66 log.c and sd-journal-send
67
bd1b3f75
LP
68* chown() tty a service is attached to after the service goes down
69
06898123
LP
70* optionally: turn on cgroup delegation for per-session scope units
71
d3aeddb8
LP
72* introduce per-unit (i.e. per-slice, per-service) journal log size limits.
73
af560fc1
LP
74* optionally, if a per-partition GPT flag is set for the root/home/… partitions
75 format the partition on next boot and unset the flag, in order to implement
76 factory reset. also, add a second flag that simply indicates whether such a
77 scheme is supported. then, add a tool (or maybe beef up systemd-dissect) to
78 show state of these flags, and optionally trigger such a factory reset on
79 next boot by setting the flag.
80
42e18088
LP
81* sd-boot: search drop-ins in $BOOT, too
82
83* sd-boot: add "oneshot boot timeout" variable support
84
85* sd-boot: automatically load EFI modules from some drop-in dir, so that people
86 can add in file system drivers and such
87
88* esp generator: also mount $BOOT if found
89
90* sd-boot: optionally, show boot menu when previous default boot item has
91 non-zero "tries done" count
92
93* logind: add "boot into bootmenu" API, and possibly even "boot into windows"
94 and "boot into macos".
95
96* bootspec.c: also enumerate EFI unified kernel images.
97
7bd4bcf7
LP
98* maybe extend .path units to expose fanotify() per-mount change events
99
a33ffd15
LP
100* Add a "systemctl list-units --by-slice" mode or so, which rearranges the
101 output of "systemctl list-units" slightly by showing the tree structure of
102 the slices, and the units attached to them.
103
20d4b101
LP
104* the a-posteriori stopping of units bound to units that disappeared logic
105 should be reworked: there should be a queue of units, and we should only
106 enqeue stop jobs from a defer event that processes queue instead of
107 right-away when we find a unit that is bound to one that doesn't exist
108 anymore. (similar to how the stop-unneeded queue has been reworked the same
109 way)
4e8113bb 110
126708fa
LP
111* nspawn: make nspawn suitable for shell pipelines: instead of triggering a
112 hangup when input is finished, send ^D, which synthesizes an EOF. Then wait
113 for hangup or ^D before passing on the EOF.
114
bb527e11
LP
115* When reloading configuration PID 1 should reset all its properties to the
116 original defaults before calling parse_config()
117
cd710e6a
LP
118* Add OnTimezoneChange= and OnTimeChange= stanzas to .timer units in order to
119 schedule events based on time and timezone changes.
120
72d711ef 121* nspawn: greater control over selinux label?
c7db2a9d 122
070d0ac9
LP
123* cgroups: figure out if we can somehow communicate in a cleaner way whether a
124 systemd instance not running in the cgroup root shall or shall not manage the
125 attributes of its top-level cgroup. Currently it assumes it manages all, but
126 then might get EPERM due to permission porblems/userns, which is OK, but this
127 should be revisited to make clearer and also work if the payload systemd runs
128 with full privs and without userns.
129
c633b0a6
LP
130* hibernate/s2h: make this robust and safe to enable in Fedora by default.
131 Specifically:
132
133 1. add resume_offset support to the resume code (i.e. support swap files
134 properly)
e83419d0 135 2. check if swap is on weird storage and refuse if so
9259d0e2 136 3. add autodetection of hibernation images
c633b0a6 137
070d0ac9
LP
138* cgroups: use inotify to get notified when somebody else modifies cgroups
139 owned by us, then log a friendly warning.
140
e44924f5
LP
141* beef up log.c with support for stripping ANSI sequences from strings, so that
142 it is OK to include them in log strings. This would be particularly useful so
143 that our log messages could contain clickable links for example for unit
144 files and suchlike we operate on.
070d0ac9 145
8c4c2dfc
LP
146* add support for "portablectl attach http://foobar.com/waaa.raw (i.e. importd integration)
147
148* add attach --enable and attach --now (for attach+enable+start)
149
150* sync dynamic uids/gids between host+portable srvice (i.e. if DynamicUser=1 is set for a service, make sure that the
151 selected user is resolvable in the service even if it ships its own /etc/passwd)
152
5da19043
LP
153* Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the
154 other doesn't. What a desaster. Probably to exclude it. Also
155 DECIMAL_STR_WIDTH should probably add an extra "-" into account for negative
156 numbers.
157
16270697
LP
158* Check that users of inotify's IN_DELETE_SELF flag are using it properly, as
159 usually IN_ATTRIB is the right way to watch deleted files, as the former only
160 fires when a file is actually removed from disk, i.e. the link count drops to
161 zero and is not open anymore, while the latter happens when a file is
162 unlinked from any dir.
163
bd1b3f75 164* port systemctl, busctl, … over to format-table.[ch]'s table formatters
5da19043 165
7bc756ff
LP
166* pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up
167
168* add --vacuum-xyz options to coredumpctl, matching those journalctl already has.
169
0bb8dfaa
LP
170* SuccessExitStatus= and friends should probably also accept symbolic exit
171 codes names, i.e. error codes from the list maintained in exit-codes.[ch]
172
53c70a27
LP
173* introduce Ephemeral= unit file switch, that creates an ephemeral copy of all
174 files and directories that are left writable for a unit, and which are
175 removed after the unit goes down again. A bit like --ephemeral for
176 systemd-nspawn but for system services. If used together with RootImage= this
177 should reflink the image file itself.
178
179 Related: add Ephemeral=<path1> <path2> … which would allow marking
180 specific paths only like this.
181
53c70a27
LP
182* add CopyFile= or so as unit file setting that may be used to copy files or
183 directory trees from the host to te services RootImage= and RootDirectory=
184 environment. Which we can use for /etc/machine-id and in particular
185 /etc/resolv.conf. Should be smart and do something useful on read-only
186 images, for example fallback to read-only bind mounting the file instead.
187
d9b50610
LP
188* nspawn's console TTY should be allocated from within the container, not
189 mounted in from the outside
190
191* show invocation ID in systemd-run output
192
193* bypass SIGTERM state in unit files if KillSignal is SIGKILL
194
195* tree-wide: ensure we always block the signals we hook into with
196 sd_event_add_signal() first
197
9711b1ad
LP
198* add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1
199 and so on, which would mean we could report errors and such.
200
1e784321
LP
201* teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4
202 project quota
0d545655 203
6b7b0f39
LP
204* introduce DefaultSlice= or so in system.conf that allows changing where we
205 place our units by default, i.e. change system.slice to something
206 else. Similar, ManagerSlice= should exist so that PID1's own scope unit could
207 be moved somewhere else too. Finally machined and logind should get similar
208 options so that it is possible to move user session scopes and machines to a
209 different slice too by default. Usecase: people who want to put resources on
210 the entire system, with the exception of one specific service. See:
211 https://lists.freedesktop.org/archives/systemd-devel/2018-February/040369.html
212
aa79f932
LP
213* maybe rework get_user_creds() to query the user database if $SHELL is used
214 for root, but only then.
586a8e93 215
46099c9e
LP
216* be stricter with fds we receive for the fdstore: close them asynchronously
217
46099c9e
LP
218* calenderspec: add support for week numbers and day numbers within a
219 year. This would allow us to define "bi-weekly" triggers safely.
220
c3cd7cc9
LP
221* sd-bus: add vtable flag, that may be used to request client creds implicitly
222 and asynchronously before dispatching the operation
223
06345858
LP
224* make use of ethtool veth peer info in machined, for automatically finding out
225 host-side interface pointing to the container.
226
48f1b5e5
LP
227* add some special mode to LogsDirectory=/StateDirectory=… that allows
228 declaring these directories without necessarily pulling in deps for them, or
229 creating them when starting up. That way, we could declare that
230 systemd-journald writes to /var/log/journal, which could be useful when we
231 doing disk usage calculations and so on.
232
cb77e122 233* taint systemd if there are fewer than 65536 users assigned (userns) to the system.
c6009ff0 234
899feb72 235* deprecate RootDirectoryStartOnly= in favour of a new ExecStart= prefix char
c6009ff0 236
3d80d454
LP
237* add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
238 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
239 as the unit is running or has a job queued.
240
5f7ecd61 241* support projid-based quota in machinectl for containers
5962e9db 242
17b6f896
LP
243* Add NetworkNamespacePath= to specify a path to a network namespace
244
17b6f896
LP
245* maybe use SOURCE_DATE_EPOCH (i.e. the env var the reproducible builds folks
246 introduced) as the RTC epoch, instead of the mtime of NEWS.
247
17b6f896
LP
248* add a way to lock down cgroup migration: a boolean, which when set for a unit
249 makes sure the processes in it can never migrate out of it
250
17b6f896
LP
251* blog about fd store and restartable services
252
253* document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
254
370f9c21
LP
255* rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
256 magic meaning and is no longer upgraded to something else if set explicitly.
257
17b6f896
LP
258* in the long run: permit a system with /etc/machine-id linked to /dev/null, to
259 make it lose its identity, i.e. be anonymous. For this we'd have to patch
260 through the whole tree to make all code deal with the case where no machine
261 ID is available.
262
263* optionally, collect cgroup resource data, and store it in per-unit RRD files,
264 suitable for processing with rrdtool. Add bus API to access this data, and
265 possibly implement a CPULoad property based on it.
266
e7e4a258
LP
267* beef up pam_systemd to take unit file settings such as cgroups properties as
268 parameters
269
e7e4a258
LP
270* a new "systemd-analyze security" tool outputting a checklist of security
271 features a service does and does not implement
272
6fc373ee
LP
273* maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
274 the quota of a the user indicated in User= via unit file settings, like the
5962e9db
LP
275 other resource management concepts. Would mix nicely with DynamicUser=1. Or
276 alternatively, do this with projids, so that we can also cover services
277 running as root. Quota should probably cover all the special dirs such as
278 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
279 is set, plus the whole disk space any image configured with RootImage=.
6fc373ee 280
9a92a97a
LP
281* Introduce "exit" as an EmergencyAction value, and allow to configure a
282 per-unit success/failure exit code to configure. This would be useful for
283 running commands inside of services inside of containers, which could then
284 propagate their failure state all the way up.
285
286* In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
287 disks to see if the UID is already in use.
288
2368e974
LP
289* add "systemctl wait" or so, which does what "systemd-run --wait" does, but
290 for all units. It should be both a way to pin units into memory as well as a
291 wait to retrieve their exit data.
292
fa991fb7
LP
293* expose IO accounting data on the bus, show it in systemd-run --wait and log
294 about it in the resource log message
295
296* add "systemctl purge" for flushing out configuration, state, logs, ... of a
297 unit when it is stopped
298
299* show whether a service has out-of-date configuration in "systemctl status" by
300 using mtime data of ConfigurationDirectory=.
301
620218fb
LP
302* replace all uses of fgets() + LINE_MAX by read_line()
303
d73b607d
LP
304* Add AddUser= setting to unit files, similar to DynamicUser=1 which however
305 creates a static, persistent user rather than a dynamic, transient user. We
306 can leverage code from sysusers.d for this.
307
fd63f36c
LP
308* add some optional flag to ReadWritePaths= and friends, that has the effect
309 that we create the dir in question when the service is started. Example:
310
311 ReadWritePaths=:/var/lib/foobar
312
3576dddf
LP
313* maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
314 the sd-journal logging socket, and, if the timeout is set to 0, sets
315 O_NONBLOCK on it. That way people can control if and when to block for
316 logging.
317
fe6a0235
LP
318* hostnamed: populate form factor data from a new hwdb database, so that old
319 yogas can be recognized as "convertible" too, even if they predate the DMI
320 "convertible" form factor
321
08422e63
LP
322* Maybe add a small tool invoked early at boot, that adds in or resizes
323 partitions automatically, to be used when the media used is actually larger
324 than the image written onto it is.
325
d543b9f5
LP
326* Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
327 after all. Be strict however, only support the equivalent of nspawn's
328 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
329 as MAINPID.
330
f59d1da8
LP
331* Add ExecMonitor= setting. May be used multiple times. Forks off a process in
332 the service cgroup, which is supposed to monitor the service, and when it
333 exits the service is considered failed by its monitor.
334
33bac67b
LP
335* track the per-service PAM process properly (i.e. as an additional control
336 process), so that it may be queried on the bus and everything.
337
338* add a new "debug" job mode, that is propagated to unit_start() and for
339 services results in two things: we raise SIGSTOP right before invoking
340 execve() and turn off watchdog support. Then, use that to implement
341 "systemd-gdb" for attaching to the start-up of any system service in its
342 natural habitat.
343
8eb7383b
LP
344* maybe introduce gpt auto discovery for /var/tmp?
345
8eb7383b
LP
346* maybe add gpt-partition-based user management: each user gets his own
347 LUKS-encrypted GPT partition with a new GPT type. A small nss module
348 enumerates users via udev partition enumeration. UIDs are assigned in a fixed
349 way: the partition index is added as offset to some fixed base uid. User name
350 is stored in GPT partition name. A PAM module authenticates the user via the
351 LUKS partition password. Benefits: strong per-user security, compatibility
352 with stateless/read-only/verity-enabled root. (other idea: do this based on
353 loopback files in /home, without GPT involvement)
354
355* gpt-auto logic: introduce support for discovering /var matching an image. For
356 that, use a partition type UUID that is hashed from the OS name (as encoded
357 in /etc/os-release), the architecture, and 4 new bits from the gpt flags
358 field of the root partition. This way can easily support multiple OS
359 installations on the same GPT partition table, without problems with
360 unmatched /var partitions.
361
362* gpt-auto logic: related to the above, maybe support a "secondary" root
363 partition, that is mounted to / and is writable, and where the actual root's
364 /usr is mounted into.
365
8eb7383b
LP
366* gpt-auto logic: support encrypted swap, add kernel cmdline option to force it, and honour a gpt bit about it, plus maybe a configuration file
367
67234d21
LP
368* drop nss-myhostname in favour of nss-resolve?
369
b5bdbcd5
LP
370* add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
371 then use that for the setting used in user@.service. It should be understood
372 relative to the configured default value.
373
d21494ea
LP
374* in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
375
376* enable LockMLOCK to take a percentage value relative to physical memory
377
04397464 378* Permit masking specific netlink APIs with RestrictAddressFamily=
d82047be 379
d82047be
LP
380* nspawn: support that /proc, /sys/, /dev are pre-mounted
381
d82047be
LP
382* define gpt header bits to select volatility mode
383
42d61ded
LP
384* ProtectKernelLogs= (drops CAP_SYSLOG, add seccomp for syslog() syscall, and DeviceAllow to /dev/kmsg) in service files
385
386* ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
387
04397464 388* ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
42d61ded 389
04397464 390* ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
563a69f4 391
04397464 392* ProtectKeyRing= to take keyring calls away
2c5f2958 393
8ce9b83a 394* RemoveKeyRing= to remove all keyring entries of the specified user
a46eac1b
LP
395
396* ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
397 on PID 1 with the relevant signals, and makes relevant files in /sys and
398 /proc (such as the sysrq stuff) unavailable
399
e40a326c 400* make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
89f193fa 401
6809de5b
LP
402* journalctl: make sure -f ends when the container indicated by -M terminates
403
2c5f2958
LP
404* mount: automatically search for "main" partition of an image has multiple
405 partitions
406
f8afc2a9
LP
407* expose the "privileged" flag of ExecCommand on the bus, and open it up to
408 transient units
409
8ce9b83a
LP
410* in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
411 find a way to map the User=/Group= of the service to the right name. This way
412 a user/group for a service only has to exist on the host for the right
413 mapping to work.
414
2c5f2958
LP
415* add bus API for creating unit files in /etc, reusing the code for transient units
416
417* add bus API to remove unit files from /etc
418
419* add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)

421* rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
422 kernel doesn't support linkat() that replaces existing files, currently)
423
1e555cb5
LP
424* transient units: don't bother with actually setting unit properties, we
425 reload the unit file anyway
426
1e555cb5
LP
427* journald: sigbus API via a signal-handler safe function that people may call
428 from the SIGBUS handler
429
c8048350
LP
430* optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
431
7a79d1ec
LP
432* resolved: when routing queries, make sure only look for the *longest* suffix...
433
648b1220
LP
434* delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
435 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
436
3d39e6e5
LP
437* cache sd_event_now() result from before the first iteration...
438
f506d09f
LP
439* add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction
440
bd098bce
LP
441* PID1: find a way how we can reload unit file configuration for
442 specific units only, without reloading the whole of systemd
443
f9bf1b8f 444* add an explicit parser for LimitRTPRIO= that verifies
de7399eb 445 the specified range and generates sane error messages for incorrect
f9bf1b8f 446 specifications.
de7399eb 447
3efc8c72
LP
448* when we detect that there are waiting jobs but no running jobs, do something
449
06ce859b 450* push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
03364e47 451
e6a26d8c
LP
452* PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
453
a2088fd0
LP
454* there's probably something wrong with having user mounts below /sys,
455 as we have for debugfs. for exmaple, src/core/mount.c handles mounts
456 prefixed with /sys generally special.
457 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
458
8aa20381
LP
459* fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
460
b18d23d7
LP
461* docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
462
60d17b74
LP
463* add a job mode that will fail if a transaction would mean stopping
464 running units. Use this in timedated to manage the NTP service
465 state.
466 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
467
2f653bde
LP
468* Maybe add support for the equivalent of "ethtool advertise" to .link files?
469 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
470
477e75ef
LP
471* The udev blkid built-in should expose a property that reflects
472 whether media was sensed in USB CF/SD card readers. This should then
473 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
474 picked up by systemd unless they contain a medium. This would mirror
475 the behaviour we already have for CD drives.
476
2bc39683
LP
477* networkd/udev: implement SR_IOV configuration in .link files:
478 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
479
c3a0d00d

LP
482* Find a solution for SMACK capabilities stuff:

98cd2651 484
2a441c8a
LP
485* "systemctl preset-all" should probably order the unit files it
486 operates on lexicographically before starting to work, in order to
487 ensure deterministic behaviour if two unit files conflict (like DMs
488 do, for example)
489
0a86c1a9
LP
490* synchronize console access with BSD locks:
491 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
492
e031c227 493* as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
0a86c1a9
LP
494 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
495
e3286870
LP
496* in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
497
8514b677
LP
498* figure out when we can use the coarse timers
499
7b0fce61
LP
500* add "systemctl start -v foobar.service" that shows logs of a service
501 while the start command runs. This is non-trivial to do without
502 races though, since we should flush out all journal messages before
503 returning from the "systemctl stop".
504
b568ef14 505* 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 506
d48b7bd2
LP
507* maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
508
8483d73f
LP
509* consider showing the unit names during boot up in the status output, not just the unit descriptions
510
8483d73f
LP
511* maybe allow timer units with an empty Units= setting, so that they
512 can be used for resuming the system but nothing else.
513
25e773ee 514* what to do about udev db binary stability for apps? (raw access is not an option)
b857e042 515
3bcde97e
LP
516* man: maybe use the word "inspect" rather than "introspect"?
517
279f0366 518* systemctl: if some operation fails, show log output?
533bb267 519
39c38ce1 520* systemctl edit: use equvalent of cat() to insert existing config as a comment, prepended with #.
b42de08a 521 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
202aea45 522
720652b3 523* exponential backoff in timesyncd when we cannot reach a server
42aeb14a 524
720652b3 525* timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
e25b5a8d 526
563b1bdc
LP
527* merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
528
5dcf9838
LP
529* systemd.show_status= should probably have a mode where only failed
530 units are shown.
531
6bd7941e
TG
532* add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
533 (throughout the codebase, not only PID1)
534
9d6db739 535* resolved:
9d6db739 536 - mDNS/DNS-SD
ccc3e8a1
LP
537 - service registration
538 - service/domain/types browsing
0f47ed0a 539 - avahi compat
9d6db739 540 - DNS-SD service registration from socket units
e25b5a8d
DH
541 - resolved should optionally register additional per-interface LLMNR
542 names, so that for the container case we can establish the same name
543 (maybe "host") for referencing the server, everywhere.
720652b3 544 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
3efb871a 545 - hook up resolved with machined-based address resolution
3f77a1b1 546
e25b5a8d 547* refcounting in sd-resolve is borked
e2a69298 548
2834ffe7
LP
549* Add a new verb "systemctl top"
550
a940778f
LP
551* add new gpt type for btrfs volumes
552
a01647e5 553* support empty /etc boots nicely:
3c779fa5 554 - nspawn/gpt-generator: introduce new gpt partition type for /usr
a01647e5 555
3de03738
LP
556* generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
557
37efac5d
LP
558* a way for container managers to turn off getty starting via $container_headless= or so...
559
7348b3ad
LP
560* figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
561
81429136
KS
562* For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
563 they run added to the initial transaction and thus confuse Type=idle.
e107ed18 564
edb2935c
LP
565* add bus api to query unit file's X fields.
566
6a3f892a 567* gpt-auto-generator:
2a781fc9 568 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
6a3f892a 569 - Make /home automount rather than mount?
6a3f892a 570
65026403
LP
571* add generator that pulls in systemd-network from containers when
572 CAP_NET_ADMIN is set, more than the loopback device is defined, even
573 when it is otherwise off
f8901862 574
f9bf1b8f 575* MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
eda8f067 576
af1082b0
LP
577* implement Distribute= in socket units to allow running multiple
578 service instances processing the listening socket, and open this up
579 for ReusePort=
580
488ad3b3
LP
581* socket units: support creating sockets in different namespace,
582 opening it up for JoinsNamespaceOf=. This would require to fork off
583 a tiny process that joins the namespace and creates/binds the socket
584 and passes this back to PID1 via SCM_RIGHTS. This also could be used
585 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
586
09ecd746
LP
587* introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
588 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
589 should SIGSTOP all unit processes in a loop until all processes of
590 it are fully stopped. This can later be used for app management by
591 desktop UIs such as gnome-shell to freeze apps that are not visible
592 on screen, not unlike how job control works on the shell
593
f38afcd0 594* cgroups:
f38afcd0
LP
595 - implement per-slice CPUFairScheduling=1 switch
596 - handle jointly mounted controllers correctly
597 - introduce high-level settings for RT budget, swappiness
598 - how to reset dynamically changed unit cgroup attributes sanely?
599 - when reloading configuration, apply new cgroup configuration
600 - when recursively showing the cgroup hierarchy, optionally also show
601 the hierarchies of child processes
0bee65f0 602
f38afcd0 603* transient units:
f38afcd0 604 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
ebcf1f97 605
47c94a96
LP
606* Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
607
718db961
LP
608* when we detect low battery and no AC on boot, show pretty splash and refuse boot
609
718db961
LP
610* libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
611
966204e0
LP
612* be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
613
41644622
LP
614* 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
615
7f79cd71 616* After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
0aafd43d 617
19aadacf
JE
618* If we try to find a unit via a dangling symlink, generate a clean
619 error. Currently, we just ignore it and read the unit from the search
df5f6971
LP
620 path anyway.
621
04397464 622* refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
fcba531e 623
bdeeb6b5
LP
624* man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
625
626* load .d/*.conf dropins for device units
627
4e09014d
LP
628* allow implementation of InaccessibleDirectories=/ plus
629 ReadOnlyDirectories=... for whitelisting files for a service.
630
6bb648a1 631* sd-bus:
0d43ffef 632 - EBADSLT handling
fa607802 633 - GetAllProperties() on a non-existing object does not result in a failure currently
7212c608 634 - port to sd-resolve for connecting to TCP dbus servers
57f2a947 635 - 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
f38afcd0 636 - see if we can drop more message validation on the sending side
f38afcd0 637 - add API to clone sd_bus_message objects
ab9716c2 638 - longer term: priority inheritance
df98a87b 639 - dbus spec updates:
df98a87b
LP
640 - NameLost/NameAcquired obsolete
641 - GVariant
2ecfc64e 642 - path escaping
6a8b5fa4 643 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
f38afcd0
LP
644
645* sd-event
12179984 646 - allow multiple signal handlers per signal?
0536ce5d 647 - document chaining of signal handler for SIGCHLD and child handlers
e25b5a8d
DH
648 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
649 - generate a failure of a default event loop is executed out-of-thread
eb01ba5d 650
69af4503 651* investigate endianness issues of UUID vs. GUID
e8a7a315 652
461bd8e4
LP
653* dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
654 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
655
ab8e074c
LP
656* add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
657
658* add a pam module that on password changes updates any LUKS slot where the password matches
659
fff87a35 660* test/:
20d52ab6 661 - add unit tests for config_parse_device_allow()
b8b4d3dd 662
b5c03638 663* seems that when we follow symlinks to units we prefer the symlink
d28315e4 664 destination path over /etc and /usr. We should not do that. Instead
b5c03638
LP
665 /etc should always override /run+/usr and also any symlink
666 destination.
667
eece8c6f
LP
668* when isolating, try to figure out a way how we implicitly can order
669 all units we stop before the isolating unit...
670
356ce991
LP
671* teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
672
c1446921
LP
673* BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
674 that the boot loader should be installed to the ESP. Define a way
675 how an installer can figure out whether a BLS compliant boot loader
676 is installed.
795607b2 677
0be8342c
LP
678* think about requeuing jobs when daemon-reload is issued? usecase:
679 the initrd issues a reload after fstab from the host is accessible
680 and we might want to requeue the mounts local-fs acquired through
681 that automatically.
682
e5ec62c5 683* systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
54c31a79 684
ccddd104 685* remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
826872b6 686
3679d112
LP
687* shutdown logging: store to EFI var, and store to USB stick?
688
356ce991 689* merge unit_kill_common() and unit_kill_context()
490b7e47 690
81d112a8 691* introduce ExecCondition= in services
490b7e47 692
b44be3ec 693* EFI:
b44be3ec
LP
694 - honor language efi variables for default language selection (if there are any?)
695 - honor timezone efi variables for default timezone selection (if there are any?)
466784c8 696 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
e4181484 697
c0fe5db5 698* maybe do not install getty@tty1.service symlink in /etc but in /usr?
e9fd44b7 699
b44be3ec 700* print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
8ed20651 701
b44be3ec 702* mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
e6c6e7af 703
b44be3ec
LP
704* logind:
705 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
b44be3ec
LP
706 - logind: wakelock/opportunistic suspend support
707 - Add pretty name for seats in logind
708 - logind: allow showing logout dialog from system?
f38afcd0
LP
709 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
710 - if pam_systemd is invoked by su from a process that is outside of a
711 any session we should probably just become a NOP, since that's
712 usually not a real user session but just some system code that just
713 needs setuid().
279f0366
LP
714 - logind: make the Suspend()/Hibernate() bus calls wait for the for
715 the job to be completed. before returning, so that clients can wait
716 for "systemctl suspend" to finish to know when the suspending is
717 complete.
718 - logind: when the power button is pressed short, just popup a
719 logout dialog. If it is pressed for 1s, do the usual
720 shutdown. Inspiration are Macs here.
279f0366 721 - expose "Locked" property on logind sesison objects
e25b5a8d
DH
722 - maybe allow configuration of the StopTimeout for session scopes
723 - rename session scope so that it includes the UID. THat way
724 the session scope can be arranged freely in slices and we don't have
725 make assumptions about their slice anymore.
726 - follow PropertiesChanged state more closely, to deal with quick logouts and
727 relogins
e673ad04 728
b44be3ec 729* exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
e673ad04 730
b44be3ec 731* journal:
57f2a947 732 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
c06bf414 733 - import and delete pstore filesystem content at startup
b44be3ec
LP
734 - journald: also get thread ID from client, plus thread name
735 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
736 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
d28315e4 737 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
b44be3ec 738 - declare the local journal protocol stable in the wiki interface chart
b44be3ec
LP
739 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
740 - journald: when dropping msgs due to ratelimit make sure to write
741 "dropped %u messages" not only when we are about to print the next
742 message that works, but alraedy after a short tiemout
743 - check if we can make journalctl by default use --follow mode inside of less if called without args?
744 - maybe add API to send pairs of iovecs via sd_journal_send
f47ec8eb 745 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
b44be3ec
LP
746 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
747 and !FOOBAR for events without FOOBAR.
038cf334
ZJS
748 - journal: store timestamp of journal_file_set_offline() int he header,
749 so it is possible to display when the file was last synced.
b44be3ec
LP
750 - 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.
751 - journal: find a way to allow dropping history early, based on priority, other rules
752 - journal: When used on NFS, check payload hashes
b44be3ec
LP
753 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
754 - refuse taking lower-case variable names in sd_journal_send() and friends.
755 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
756 - journal: deal nicely with byte-by-byte copied files, especially regards header
b44be3ec 757 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
601d9d6f 758 - Replace utmp, wtmp, btmp, and lastlog completely with journal
f38afcd0 759 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
f38afcd0
LP
760 - when a kernel driver logs in a tight loop, we should ratelimit that too.
761 - journald: optionally, log debug messages to /run but everything else to /var
762 - journald: when we drop syslog messages because the syslog socket is
763 full, make sure to write how many messages are lost as first thing
764 to syslog when it works again.
f38afcd0
LP
765 - change systemd-journal-flush into a service that stays around during
766 boot, and causes the journal to be moved back to /run on shutdown,
d28315e4 767 so that we do not keep /var busy. This needs to happen synchronously,
f38afcd0 768 hence doing this via signals is not going to work.
279f0366
LP
769 - optionally support running journald from the command line for testing purposes in external projects
770 - journald: allow per-priority and per-service retention times when rotating/vacuuming
771 - journald: make use of uid-range.h to managed uid ranges to split
772 journals in.
773 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
774 - improve journalctl performance by loading journal files
775 lazily. Encode just enough information in the file name, so that we
776 do not have to open it to know that it is not interesting for us, for
777 the most common operations.
e25b5a8d 778 - man: document that corrupted journal files is nothing to act on
e25b5a8d
DH
779 - rework journald sigbus stuff to use mutex
780 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
781 services that run under their own user ids, and use User= (but only
782 in a world where userns is ubiquitous since otherwise we cannot
783 invoke those daemons on the host AND in a container anymore). Also,
784 if LimitNPROC= is used without User= we should warn and refuse
785 operation.
786 - journalctl --verify: don't show files that are currently being
787 written to as FAIL, but instead show that their are being written to.
788 - add journalctl -H that talks via ssh to a remote peer and passes through
789 binary logs data
e25b5a8d 790 - add a version of --merge which also merges /var/log/journal/remote
e25b5a8d
DH
791 - journalctl: -m should access container journals directly by enumerating
792 them via machined, and also watch containers coming and going.
793 Benefit: nspawn --ephemeral would start working nicely with the journal.
794 - assign MESSAGE_ID to log messages about failed services
b44be3ec 795
590171d1
ZJS
796* add a test if all entries in the catalog are properly formatted.
797 (Adding dashes in a catalog entry currently results in the catalog entry
798 being silently skipped. journalctl --update-catalog must warn about this,
799 and we should also have a unit test to check that all our message are OK.)
800
b44be3ec 801* document:
8b8f2591 802 - document that deps in [Unit] sections ignore Alias= fields in
b44be3ec
LP
803 [Install] units of other units, unless those units are disabled
804 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
b44be3ec 805 - document that service reload may be implemented as service reexec
f38afcd0
LP
806 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
807 - document systemd-journal-flush.service properly
f38afcd0
LP
808 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
809 - man: document the very specific env the shutdown drop-in tools live in
f38afcd0
LP
810 - man: add more examples to man pages
811 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
b44be3ec
LP
812
813* systemctl:
b44be3ec
LP
814 - add systemctl switch to dump transaction without executing it
815 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
816 - "systemctl disable" on a static unit prints no message and does
817 nothing. "systemctl enable" does nothing, and gives a bad message
818 about it. Should fix both to print nice actionable messages.
819 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
820 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
d28315e4 821 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
b44be3ec 822 - systemctl: "Journal has been rotated since unit was started." message is misleading
61233823 823 - systemctl status output should include list of triggering units and their status
f38afcd0
LP
824
825* unit install:
826 - "systemctl mask" should find all names by which a unit is accessible
827 (i.e. by scanning for symlinks to it) and link them all to /dev/null
8b04b925 828
b44be3ec 829* timer units:
b44be3ec
LP
830 - timer units should get the ability to trigger when:
831 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
832 o DST changes
4db688e0 833 o timezone changes
90e071d1 834 - Modulate timer frequency based on battery state
d2e83c23 835

a7a3f28b
LP
838* clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
839
b44be3ec 840* on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
08f95888 841
f59d1da8 842* make repeated alt-ctrl-del presses printing a dump
dcfc4b2e 843

LP
844* hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
845
d28315e4 846* currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
1b89884b 847
b44be3ec 848* nspawn:
e25b5a8d
DH
849 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
850 with seccomp. That should provide us with a useful log buffer that
851 systemd can log to during early boot, and disconnect container logs
852 from the kernel's logs.
853 - as soon as networkd has a bus interface, hook up --network-interface=,
854 --network-bridge= with networkd, to trigger netdev creation should an
855 interface be missing
e25b5a8d
DH
856 - a nice way to boot up without machine id set, so that it is set at boot
857 automatically for supporting --ephemeral. Maybe hash the host machine id
858 together with the machine name to generate the machine id for the container
859 - fix logic always print a final newline on output.
860 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
861 - should optionally support receiving WATCHDOG=1 messages from its payload
862 PID 1...
e25b5a8d
DH
863 - optionally automatically add FORWARD rules to iptables whenever nspawn is
864 running, remove them when shut down.
e25b5a8d
DH
865 - maybe make copying of /etc/resolv.conf optional, and skip it if --read-only
866 is used
867
347a17d5
ZJS
868* dissect
869 - refuse mounting over a mount point
870 - automatically discover .roothash files in dissect, similarly to nspawn
871
e25b5a8d 872* machined:
e25b5a8d
DH
873 - add an API so that libvirt-lxc can inform us about network interfaces being
874 removed or added to an existing machine
875 - "machinectl migrate" or similar to copy a container from or to a
876 difference host, via ssh
e25b5a8d
DH
877 - introduce systemd-nspawn-ephemeral@.service, and hook it into
878 "machinectl start" with a new --ephemeral switch
879 - "machinectl status" should also show internal logs of the container in
880 question
e25b5a8d
DH
881 - "machinectl history"
882 - "machinectl diff"
883 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
884 shell in it, and marks it read-only after use
885
b44be3ec 886* cryptsetup:
b44be3ec 887 - cryptsetup-generator: allow specification of passwords in crypttab itself
5f1dac6b 888 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
f8019684 889
424a19f8 890* hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it

abd55b16
KS
903 - kill scsi_id
904 - add trigger --subsystem-match=usb/usb_device device
e8d842a0 905 - reimport udev db after MOVE events for devices without dev_t
b8217b7b 906
7f110ff9
LP
907* There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
908
d0e5a333
LP
909* add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
910
e25b5a8d
DH
911* coredump:
912 - save coredump in Windows/Mozilla minidump format
73a99163 913 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
87a8baa3
LP
914
915* support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
916
70a44afe 917* default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max

f957632b
KS
919* be able to specify a forced restart of service A where service B depends on, in case B
920 needs to be auto-respawned?
921
f38afcd0 922* tmpfiles:
f38afcd0 923 - apply "x" on "D" too (see patch from William Douglas)
614cc34f
ZJS
924 - replace F with f+.
925 - instead of ignoring unknown fields, reject them.
e25b5a8d
DH
926 - creating new directories/subvolumes/fifos/device nodes
927 should not follow symlinks. None of the other adjustment or creation
928 calls follow symlinks.
1258097c 929
a4c279f8
LP
930* make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
931
f28f1daf
LP
932* verify that the AF_UNIX sockets of a service in the fs still exist
933 when we start a service in order to avoid confusion when a user
934 assumes starting a service is enough to make it accessible
935
88a07670
LP
936* Make it possible to set the keymap independently from the font on
937 the kernel cmdline. Right now setting one resets also the other.
938
71092d70 939* and a dbus call to generate target from current state

961
59fee421
LP
962* dot output for --test showing the 'initial transaction'
963
e25b5a8d 964* pid1:
e25b5a8d
DH
965 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
966 log both units as UNIT=, so that journalctl -u triggers on both.
967 - generate better errors when people try to set transient properties
968 that are not supported...
969 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
970 - maybe introduce WantsMountsFor=? Usecase:
971 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
972 - recreate systemd's D-Bus private socket file on SIGUSR2
e25b5a8d
DH
973 - move PAM code into its own binary
974 - when we automatically restart a service, ensure we restart its rdeps, too.
e25b5a8d
DH
975 - hide PAM options in fragment parser when compile time disabled
976 - Support --test based on current system state
977 - 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().
978 - after deserializing sockets in socket.c we should reapply sockopts and things
e25b5a8d
DH
979 - drop PID 1 reloading, only do reexecing (difficult: Reload()
980 currently is properly synchronous, Reexec() is weird, because we
981 cannot delay the response properly until we are back, so instead of
982 being properly synchronous we just keep open the fd and close it
983 when done. That means clients do not get a successful method reply,
984 but much rather a disconnect on success.
985 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
986 - when a bus name of a service disappears from the bus make sure to queue further activation requests
987
988* unit files:
989 - allow port=0 in .socket units
990 - maybe introduce ExecRestartPre=
991 - add ReloadSignal= for configuring a reload signal to use
992 - implement Register= switch in .socket units to enable registration
993 in Avahi, RPC and other socket registration services.
994 - allow Type=simple with PIDFile=
995 https://bugzilla.redhat.com/show_bug.cgi?id=723942
996 - allow writing multiple conditions in unit files on one line
997 - load-fragment: when loading a unit file via a chain of symlinks
998 verify that it is not masked via any of the names traversed.
999 - introduce Type=pid-file
e25b5a8d
DH
1000 - introduce mix of BindTo and Requisite
1001 - add a concept of RemainAfterExit= to scope units
e25b5a8d 1002 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
e25b5a8d 1003
af6f0d42
TG
1004* udev-link-config:
1005 - Make sure ID_PATH is always exported and complete for
1006 network devices where possible, so we can safely rely
1007 on Path= matching
8faf88e5 1008 - check MTUBytes parsing (expecting size_t but we are using unsigned)
af6f0d42 1009
88e4d1d7 1010* sd-rtnl:

0a4b9a07 1017 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
e8d842a0 1018 - add reduced [Link] support to .network files
5c1d3fc9 1019 - add Scope= parsing option for [Network]

a8eaaee7 1021 - work with non-Ethernet devices
c9fa3670 1022 - add support for more bond options
e25b5a8d 1023 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
e25b5a8d
DH
1024 - the DHCP lease data (such as NTP/DNS) is still made available when
1025 a carrier is lost on a link. It should be removed instantly.
1026 - expose in the API the following bits:
1027 - option 15, domain name and/or option 119, search list
1028 - option 12, host name and/or option 81, fqdn
1029 - option 123, 144, geolocation
1030 - option 252, configure http proxy (PAC/wpad)
1031 - provide a way to define a per-network interface default metric value
1032 for all routes to it. possibly a second default for DHCP routes.
1033 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
1034 support Name=foo*|bar*|baz ?
1035 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
1036 - allow DUID/IAID to be customized, see issue #394.

37d8b536
PF
1051 - implement dhcpv6 authentication
1052 - investigate the usefulness of Confirm messages; i.e. are there any
1053 situations where the link changes without any loss in carrier detection
1054 or interface down
1055 - some servers don't do rapid commit without a filled in IA_NA, verify
1056 this behavior
