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

5e524b40
LP
16Janitorial Clean-ups:
17
5e524b40
LP
18* Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
19
bb527e11
LP
20* rework mount.c and swap.c to follow proper state enumeration/deserialization
21 semantics, like we do for device.c now
22
c6407108
LP
23Features:
24
1f7c6f90
LP
25* homed: permit multiple private keys to be used locally, and pick the right
26 one for signing records automatically depending on a pre-existing signature
27
28* homed: add a way to "adopt" a home directory, i.e. strip foreign signatures
29 and insert a local signature instead.
30
c98fef26
LP
31* busctl: maybe expose a verb "ping" for pinging a dbus service to see if it
32 exists and responds.
33
185924ab
LP
34* homed: add homed.conf setting DefaultStorage= or so
35
c5ca6d90
LP
36* homed: maybe pre-create ~/.cache as subvol so that it can have separate quota
37 easily?
38
6663cfd5
LP
39* journalctl --image= which is like --root= but operates on disk images
40
41* when systemd-nspawn and suchlike dissect an OS image, and there are multiple
42 root partitions, do an strverscmp() on the partition label and boot
43 first. That is inspired how sd-boot figures out which kernel to boot, and
44 thus allows defining OS images which can be A/B updated and we default to the
45 newest version automatically, both in nspawn and in sd-boot
46
97cd52c1 47* cryptsetup/homed: also support FIDO2 HMAC password logic for unlocking
70e9d9a5 48 devices. (see: https://github.com/mjec/fido2-hmac-secret)
97cd52c1 49
d200253b
LP
50* systemd-gpt-auto should probably set x-systemd.growfs on the mounts it
51 creates
52
86b52a39 53* homed/userdb: distinguish passwords and recovery keys in the records, since
006c44c1
LP
54 we probably want to use different PBKDF algorithms/settings for them:
55 passwords have low entropy but recovery keys should have good entropy key
56 hence we can make them quicker to work.
57
492f91d8
LP
58* bootctl:
59 - teach it to prepare an ESP wholesale, i.e. with mkfs.vfat invocation
60 - teach it to copy in unified kernel images and maybe type #1 boot loader spec entries from host
61 - make it operate on loopback files, dissecting enough to find ESP to operate on
62
e1d32d6e
LP
63* by default, in systemd --user service bump the OOMAdjust to 100, as privs
64 allow so that systemd survives
65
c809ed78
LP
66* cryptsetup: allow encoding key directly in /etc/crypttab, maybe with a
67 "base64:" prefix. Useful in particular for pkcs11 mode.
68
56a061f5
LP
69* cryptsetup: reimplement the mkswap/mke2fs in cryptsetup-generator to use
70 systemd-makefs.service instead.
71
91fc013f 72* socket units: allow creating a udev monitor socket with ListenDevices= or so,
86b52a39 73 with matches, then activate app through that passing socket over
91fc013f 74
492f91d8
LP
75* unify on openssl:
76 - port sd_id128_get_machine_app_specific() over from khash
77 - port resolved over from libgcrypt (DNSSEC code)
78 - port journald + fsprg over from libgcrypt
79 - port importd over from libgcrypt
80 - when that's done: kill khash.c
81 - when that's done: kill gnutls support in resolved
82
0e7e8544
LP
83* kill zenata, all hail weblate?
84
492f91d8
LP
85* when we resize disks (homed?) always round up to 4K sectors, not 512K
86
87* add growvol and makevol options for /etc/crypttab, similar to
88 x-systemd.growfs and x-systemd-makefs.
89
90* hook up the TPM to /etc/crypttab, with a new option that is similar to the
91 new PKCS#11 option in crypttab, and allows unlocking a LUKS volume via a key
92 unsealed from the TPM. Optionally, if TPM is not available fall back to
93 TPM-less mode, and set up linear DM mapping instead (inspired by kpartx), so
94 that the device paths stay the same, regardless if crypto is used or not.
95
492f91d8 96* systemd-repart: by default generate minimized partition tables (i.e. tables
86b52a39 97 that only cover the space actually used, excluding any free space at the
492f91d8
LP
98 end), in order to maximize dd'ability. Requires libfdisk work, see
99 https://github.com/karelzak/util-linux/issues/907
100
86b52a39 101* systemd-repart: optionally, allow specifying a path to initialize new
492f91d8
LP
102 partitions from, i.e. an fs image file or a source device node. This would
103 then turn systemd-repart into a simple installer: with a few .repart files
006c44c1
LP
104 you could replicate the host system on another device. a full installer would
105 then be: "systemd-repart /dev/sda && bootctl install /dev/sda &&
106 systemd-firstboot --image= …"
492f91d8
LP
107
108* systemd-repart: MBR partition table support. Care needs to be taken regarding
109 Type=, so that partition definitions can sanely apply to both the GPT and the
110 MBR case. Idea: accept syntax "Type=gpt:home mbr:0x83" for setting the types
111 for the two partition types explicitly. And provide an internal mapping so
112 that "Type=linux-generic" maps to the right types for both partition tables
113 automatically.
114
115* systemd-repart: allow sizing partitions as factor of available RAM, so that
116 we can reasonably size swap partitions for hibernation.
117
006c44c1
LP
118* systemd-repart: allow running mkfs before making partitions pop up +
119 encryption via LUKS to allow booting into an empty root with only /usr mounted in
120
121* systemd-repart: allow managing the gpt read-only partition flag + auto-mount flag
122
123* systemd-repart: allow disabling growing of specific partitions, or making
124 them (think ESP: we don't ever want to grow it, since we cannot resize vfat)
125
126* systemd-repart: add specifier expansion, add especifier that refers to root
127 device node of current system, /usr device node, and matching verity, so that
128 an installer can be made a "copy" installer of the booted OS
129
2a4be3c5 130* systemd-repart: make it a static checker during early boot for existence and
006c44c1
LP
131 absence of other partitions for trusted boot environments
132
133* systemd-repart: when no configuration is found, exit early do not check
134 partition table, so that it is safe to run in the initrd on any system
135
136* systemd-repart: allow config of partition uuid
137
77b19caf
LP
138* userdb: allow username prefix searches in varlink API, allow realname and
139 realname substr searches in varlink API
006c44c1 140
76410e98
LP
141* userdb: allow uid/gid range checks
142
2a4be3c5 143* userdb: allow existence checks
006c44c1
LP
144
145* pid: activation by journal search expression
146
492f91d8
LP
147* when switching root from initrd to host, set the machine_id env var so that
148 if the host has no machine ID set yet we continue to use the random one the
149 initrd had set.
150
173c7873
LP
151* sd-event: add native support for P_ALL waitid() watching, then move PID 1 to
152 it fo reaping assigned but unknown children. This needs to some special care
153 to operate somewhat sensibly in light of priorities: P_ALL will return
154 arbitrary processes, regardless of the priority we want to watch them with,
155 hence on each event loop iteration check all processes which we shall watch
156 with higher prio explicitly, and then watch the entire rest with P_ALL.
157
158* tweak sd-event's child watching: keep a prioq of children to watch and use
159 waitid() only on the children with the highest priority until one is waitable
160 and ignore all lower-prio ones from that point on
161
173c7873
LP
162* maybe introduce xattrs that can be set on the root dir of the root fs
163 partition that declare the volatility mode to use the image in. Previously I
164 thought marking this via GPT partition flags but that's not ideal since
165 that's outside of the LUKS encryption/verity verification, and we probably
166 shouldn't operate in a volatile mode unless we got told so from a trusted
167 source.
168
173c7873
LP
169* figure out automatic partition discovery when combining writable root dir
170 with immutable /usr
171
97e5cc88
LP
172* coredump: maybe when coredumping read a new xattr from /proc/$PID/exe that
173 may be used to mark a whole binary as non-coredumpable. Would fix:
174 https://bugs.freedesktop.org/show_bug.cgi?id=69447
175
f3e361c1
LP
176* teach parse_timestamp() timezones like the calendar spec already knows it
177
9ef3376b
LP
178* beef up hibernation to optionally do swapon/swapoff immediately before/after
179 the hibernation
180
c846b233
LP
181* beef up s2h to implement a battery watch loop: instead of entering
182 hibernation unconditionally after coming back from resume make a decision
183 based on the battery load level: if battery level is above a specific
184 threshold, go to suspend again, only hibernate if below it. This means we'd
185 stick to suspend usually, but fall back to hibernation only when battery runs
186 empty (well, subject to our sampling interval). Related to this, check if we
187 can make ACPI _BTP (i.e. /sys/class/power_supply/*/alarm) work for us too,
188 i.e. see if it can wake up machines from suspend, so that we could resume
189 automatically when the system is low on power and move automatically to
190 hibernation mode. (see
191 https://uefi.org/sites/default/files/resources/ACPI%206_2_A_Sept29.pdf
192 section 10.2.2.8 and
193 https://docs.microsoft.com/en-us/windows-hardware/design/device-experiences/modern-standby-wake-sources
194 at the end).
195
f293fc51
LP
196* add an explicit "vertical" mode to format-table, so that "systemctl
197 status"-like outputs (i.e. with a series of field names left and values
198 right) become genuine first class citizens, and we gain automatic, sane JSON
199 output for them.
200
f293fc51
LP
201* systemd-firstboot: teach it dissector magic, so that you can point it to some
202 disk image and it will just set everything in it all behind the scenes.
203
204* systemd-firstboot: add --force mode that replaces existing configuration.
205
9c230b8f
LP
206* We should probably replace /var/log/README, /etc/rc.d/README with symlinks
207 that are linked to these places instead of copied. After all they are
208 constant vendor data.
209
312dc153
LP
210* maybe add kernel cmdline params: 1) to force first-boot mode + 2) to force
211 random seed crediting
212
213* nspawn: on cgroupsv1 issue cgroup empty handler process based on host events,
214 so that we make cgroup agent logic safe
215
216* nspawn/machined: add API to invoke binary in container, then use that as
217 fallback in "machinectl shell"
72bd8525 218
ac5dca64
LP
219* logind: rework pam_logind to also do a bus call in case of invocation from
220 user@.service, which returns the XDG_RUNTIME_DIR value, and make this
221 behaviour selectable via pam module option.
222
c809ed78
LP
223* homed:
224 - when user tries to log into record signed by unrecognized key, automatically add key to our chain after polkit auth
225 - hook up machined/nspawn users with a varlink user query interface
226 - rollback when resize fails mid-operation
227 - GNOME's side for forget key on suspend (requires rework so that lock screen runs outside of uid)
228 - resize on login?
c809ed78
LP
229 - shrink fs on logout?
230 - update LUKS password on login if we find there's a password that unlocks the JSON record but not the LUKS device.
231 - create on activate?
232 - properties: icon url?, preferred session type?, administrator bool (which translates to 'wheel' membership)?, address?, telephone?, vcard?, samba stuff?, parental controls?
233 - communicate clearly when usb stick is safe to remove. probably involves
234 beefing up logind to make pam session close hook synchronous and wait until
235 systemd --user is shut down.
236 - logind: maybe keep a "busy fd" as long as there's a non-released session around or the user@.service
237 - maybe make automatic, read-only, time-based reflink-copies of LUKS disk images (think: time machine)
86b52a39 238 - distinguish destroy / remove (i.e. currently we can unregister a user, unregister+remove their home directory, but not just remove their home directory)
c809ed78
LP
239 - in systemd's PAMName= logic: query passwords with ssh-askpassword, so that we can make "loginctl set-linger" mode work
240 - fingerprint authentication, pattern authentication, …
241 - make sure "classic" user records can also be managed by homed
242 - description field for groups
243 - make size of $XDG_RUNTIME_DIR configurable in user record
244 - reuse pwquality magic in firstboot
245 - query password from kernel keyring first
246 - update even if record is "absent"
247 - add a "access mode" + "fstype" field to the "status" section of json identity records reflecting the actually used access mode and fstype, even on non-luks backends
248 - move acct mgmt stuff from pam_systemd_home to pam_systemd?
249 - when "homectl --pkcs11-token-uri=" is used, synthesize ssh-authorized-keys records for all keys we have private keys on the stick for
250 - make slice for users configurable (requires logind rework)
251 - logind: populate auto-login list bus property from PKCS#11 token
252 - when determining state of a LUKS home directory, check DM suspended sysfs file
253
ac5dca64
LP
254* introduce a new per-process uuid, similar to the boot id, the machine id, the
255 invocation id, that is derived from process creds, specifically a hashed
256 combination of AT_RANDOM + getpid() + the starttime from
257 /proc/self/status. Then add these ids implicitly when logging. Deriving this
258 uuid from these three things has the benefit that it can be derived easily
259 from /proc/$PID/ in a stable, and unique way that changes on both fork() and
260 exec().
261
262* let's not GC a unit while its ratelimits are still pending
263
5daeeecf
LP
264* when killing due to service watchdog timeout maybe detect whether target
265 process is under ptracing and then log loudly and continue instead.
266
5802d977
LP
267* introduce a new group to own TPM devices
268
269* make rfkill uaccess controllable by default, i.e. steal rule from
270 gnome-bluetooth and friends
271
d84520e9
LP
272* tweak journald context caching. In addition to caching per-process attributes
273 keyed by PID, cache per-cgroup attributes (i.e. the various xattrs we read)
274 keyed by cgroup path, and guarded by ctime changes. This should provide us
275 with a nice speed-up on services that have many processes running in the same
276 cgroup.
277
03ccc7f0
LP
278* make MAINPID= message reception checks even stricter: if service uses User=,
279 then check sending UID and ignore message if it doesn't match the user or
280 root.
281
282* maybe trigger a uevent "change" on a device if "systemctl reload xyz.device"
283 is issued.
284
db3cea22
LP
285* when importing an fs tree with machined, optionally apply userns-rec-chown
286
287* when importing an fs tree with machined, complain if image is not an OS
288
707b3fbd
LP
289* Maybe introduce a helper safe_exec() or so, which is to execve() which
290 safe_fork() is to fork(). And then make revert the RLIMIT_NOFILE soft limit
291 to 1K implicitly, unless explicitly opted-out.
d7b659ef 292
d238709c 293* rework seccomp/nnp logic that even if User= is used in combination with
d96c081a
LP
294 a seccomp option we don't have to set NNP. For that, change uid first whil
295 keeping CAP_SYS_ADMIN, then apply seccomp, the drop cap.
296
06bd149a
LP
297* add a concept for automatically loading per-unit secrets off disk and
298 inserting them into the kernel keyring. Maybe SecretsDirectory= similar to
299 ConfigurationDirectory=.
300
8a7cf157
LP
301* when no locale is configured, default to UEFI's PlatformLang variable
302
d3584ec4 303* bootctl,sd-boot: actually honour the "architecture" key
fe1bff15 304
d96c081a
LP
305* add a new syscall group "@esoteric" for more esoteric stuff such as bpf() and
306 usefaultd() and make systemd-analyze check for it.
307
06898123 308* paranoia: whenever we process passwords, call mlock() on the memory
309c6b19 309 first. i.e. look for all places we use free_and_erasep() and
9ae4ef49 310 augment them with mlock(). Also use MADV_DONTDUMP.
06898123 311
32875617
LP
312* Move RestrictAddressFamily= to the new cgroup create socket
313
314* support the bind/connect/sendmsg cgroup stuff for sandboxing, and possibly
315 patching around
316
76853293
LP
317* maybe implicitly attach monotonic+realtime timestamps to outgoing messages in
318 log.c and sd-journal-send
319
06898123
LP
320* optionally: turn on cgroup delegation for per-session scope units
321
d3aeddb8
LP
322* introduce per-unit (i.e. per-slice, per-service) journal log size limits.
323
42e18088
LP
324* sd-boot: automatically load EFI modules from some drop-in dir, so that people
325 can add in file system drivers and such
326
42e18088
LP
327* sd-boot: optionally, show boot menu when previous default boot item has
328 non-zero "tries done" count
329
8f2eb730
LP
330* introduce an option (or replacement) for "systemctl show" that outputs all
331 properties as JSON, similar to busctl's new JSON output. In contrast to that
332 it should skip the variant type string though.
333
334* augment CODE_FILE=, CODE_LINE= with something like CODE_BASE= or so which
335 contains some identifier for the project, which allows us to include
336 clickable links to source files generating these log messages. The identifier
337 could be some abberviated URL prefix or so (taking inspiration from Go
338 imports). For example, for systemd we could use
339 CODE_BASE=github.com/systemd/systemd/blob/98b0b1123cc or so which is
340 sufficient to build a link by prefixing "http://" and suffixing the
341 CODE_FILE.
342
8f2eb730
LP
343* Augment MESSAGE_ID with MESSAGE_BASE, in a similar fashion so that we can
344 make clickable links from log messages carrying a MESSAGE_ID, that lead to
345 some explanatory text online.
346
7bd4bcf7
LP
347* maybe extend .path units to expose fanotify() per-mount change events
348
a33ffd15
LP
349* Add a "systemctl list-units --by-slice" mode or so, which rearranges the
350 output of "systemctl list-units" slightly by showing the tree structure of
351 the slices, and the units attached to them.
352
20d4b101
LP
353* the a-posteriori stopping of units bound to units that disappeared logic
354 should be reworked: there should be a queue of units, and we should only
bc130b68 355 enqueue stop jobs from a defer event that processes queue instead of
20d4b101
LP
356 right-away when we find a unit that is bound to one that doesn't exist
357 anymore. (similar to how the stop-unneeded queue has been reworked the same
358 way)
4e8113bb 359
126708fa
LP
360* nspawn: make nspawn suitable for shell pipelines: instead of triggering a
361 hangup when input is finished, send ^D, which synthesizes an EOF. Then wait
362 for hangup or ^D before passing on the EOF.
363
bb527e11
LP
364* When reloading configuration PID 1 should reset all its properties to the
365 original defaults before calling parse_config()
366
72d711ef 367* nspawn: greater control over selinux label?
c7db2a9d 368
c633b0a6
LP
369* hibernate/s2h: make this robust and safe to enable in Fedora by default.
370 Specifically:
371
372 1. add resume_offset support to the resume code (i.e. support swap files
373 properly)
e83419d0 374 2. check if swap is on weird storage and refuse if so
46c41478 375 3. add auto-detection of hibernation images
c633b0a6 376
070d0ac9
LP
377* cgroups: use inotify to get notified when somebody else modifies cgroups
378 owned by us, then log a friendly warning.
379
e44924f5
LP
380* beef up log.c with support for stripping ANSI sequences from strings, so that
381 it is OK to include them in log strings. This would be particularly useful so
382 that our log messages could contain clickable links for example for unit
383 files and suchlike we operate on.
070d0ac9 384
8c4c2dfc
LP
385* add support for "portablectl attach http://foobar.com/waaa.raw (i.e. importd integration)
386
387* add attach --enable and attach --now (for attach+enable+start)
388
389* sync dynamic uids/gids between host+portable srvice (i.e. if DynamicUser=1 is set for a service, make sure that the
390 selected user is resolvable in the service even if it ships its own /etc/passwd)
391
5da19043 392* Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the
5238e957 393 other doesn't. What a disaster. Probably to exclude it. Also
5da19043
LP
394 DECIMAL_STR_WIDTH should probably add an extra "-" into account for negative
395 numbers.
396
16270697
LP
397* Check that users of inotify's IN_DELETE_SELF flag are using it properly, as
398 usually IN_ATTRIB is the right way to watch deleted files, as the former only
399 fires when a file is actually removed from disk, i.e. the link count drops to
400 zero and is not open anymore, while the latter happens when a file is
401 unlinked from any dir.
402
bd1b3f75 403* port systemctl, busctl, … over to format-table.[ch]'s table formatters
5da19043 404
7bc756ff
LP
405* pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up
406
407* add --vacuum-xyz options to coredumpctl, matching those journalctl already has.
408
53c70a27
LP
409* introduce Ephemeral= unit file switch, that creates an ephemeral copy of all
410 files and directories that are left writable for a unit, and which are
411 removed after the unit goes down again. A bit like --ephemeral for
412 systemd-nspawn but for system services. If used together with RootImage= this
413 should reflink the image file itself.
414
415 Related: add Ephemeral=<path1> <path2> … which would allow marking
416 specific paths only like this.
417
53c70a27 418* add CopyFile= or so as unit file setting that may be used to copy files or
5238e957 419 directory trees from the host to the services RootImage= and RootDirectory=
53c70a27
LP
420 environment. Which we can use for /etc/machine-id and in particular
421 /etc/resolv.conf. Should be smart and do something useful on read-only
422 images, for example fallback to read-only bind mounting the file instead.
423
d9b50610
LP
424* show invocation ID in systemd-run output
425
426* bypass SIGTERM state in unit files if KillSignal is SIGKILL
427
9711b1ad
LP
428* add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1
429 and so on, which would mean we could report errors and such.
430
1e784321
LP
431* teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4
432 project quota
0d545655 433
6b7b0f39
LP
434* introduce DefaultSlice= or so in system.conf that allows changing where we
435 place our units by default, i.e. change system.slice to something
436 else. Similar, ManagerSlice= should exist so that PID1's own scope unit could
437 be moved somewhere else too. Finally machined and logind should get similar
438 options so that it is possible to move user session scopes and machines to a
439 different slice too by default. Usecase: people who want to put resources on
440 the entire system, with the exception of one specific service. See:
441 https://lists.freedesktop.org/archives/systemd-devel/2018-February/040369.html
442
aa79f932
LP
443* maybe rework get_user_creds() to query the user database if $SHELL is used
444 for root, but only then.
586a8e93 445
46099c9e
LP
446* be stricter with fds we receive for the fdstore: close them asynchronously
447
46099c9e
LP
448* calenderspec: add support for week numbers and day numbers within a
449 year. This would allow us to define "bi-weekly" triggers safely.
450
c3cd7cc9
LP
451* sd-bus: add vtable flag, that may be used to request client creds implicitly
452 and asynchronously before dispatching the operation
453
06345858
LP
454* make use of ethtool veth peer info in machined, for automatically finding out
455 host-side interface pointing to the container.
456
48f1b5e5
LP
457* add some special mode to LogsDirectory=/StateDirectory=… that allows
458 declaring these directories without necessarily pulling in deps for them, or
459 creating them when starting up. That way, we could declare that
460 systemd-journald writes to /var/log/journal, which could be useful when we
461 doing disk usage calculations and so on.
462
cb77e122 463* taint systemd if there are fewer than 65536 users assigned (userns) to the system.
c6009ff0 464
899feb72 465* deprecate RootDirectoryStartOnly= in favour of a new ExecStart= prefix char
c6009ff0 466
3d80d454
LP
467* add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
468 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
469 as the unit is running or has a job queued.
470
5f7ecd61 471* support projid-based quota in machinectl for containers
5962e9db 472
17b6f896
LP
473* maybe use SOURCE_DATE_EPOCH (i.e. the env var the reproducible builds folks
474 introduced) as the RTC epoch, instead of the mtime of NEWS.
475
17b6f896
LP
476* add a way to lock down cgroup migration: a boolean, which when set for a unit
477 makes sure the processes in it can never migrate out of it
478
17b6f896
LP
479* blog about fd store and restartable services
480
481* document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
482
370f9c21
LP
483* rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
484 magic meaning and is no longer upgraded to something else if set explicitly.
485
17b6f896
LP
486* in the long run: permit a system with /etc/machine-id linked to /dev/null, to
487 make it lose its identity, i.e. be anonymous. For this we'd have to patch
488 through the whole tree to make all code deal with the case where no machine
489 ID is available.
490
491* optionally, collect cgroup resource data, and store it in per-unit RRD files,
492 suitable for processing with rrdtool. Add bus API to access this data, and
493 possibly implement a CPULoad property based on it.
494
e7e4a258
LP
495* beef up pam_systemd to take unit file settings such as cgroups properties as
496 parameters
497
6fc373ee
LP
498* maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
499 the quota of a the user indicated in User= via unit file settings, like the
5962e9db
LP
500 other resource management concepts. Would mix nicely with DynamicUser=1. Or
501 alternatively, do this with projids, so that we can also cover services
502 running as root. Quota should probably cover all the special dirs such as
503 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
504 is set, plus the whole disk space any image configured with RootImage=.
6fc373ee 505
9a92a97a
LP
506* In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
507 disks to see if the UID is already in use.
508
2368e974
LP
509* add "systemctl wait" or so, which does what "systemd-run --wait" does, but
510 for all units. It should be both a way to pin units into memory as well as a
511 wait to retrieve their exit data.
512
fa991fb7
LP
513* expose IO accounting data on the bus, show it in systemd-run --wait and log
514 about it in the resource log message
515
fa991fb7
LP
516* show whether a service has out-of-date configuration in "systemctl status" by
517 using mtime data of ConfigurationDirectory=.
518
d73b607d
LP
519* Add AddUser= setting to unit files, similar to DynamicUser=1 which however
520 creates a static, persistent user rather than a dynamic, transient user. We
521 can leverage code from sysusers.d for this.
522
fd63f36c
LP
523* add some optional flag to ReadWritePaths= and friends, that has the effect
524 that we create the dir in question when the service is started. Example:
525
526 ReadWritePaths=:/var/lib/foobar
527
3576dddf
LP
528* maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
529 the sd-journal logging socket, and, if the timeout is set to 0, sets
530 O_NONBLOCK on it. That way people can control if and when to block for
531 logging.
532
fe6a0235
LP
533* hostnamed: populate form factor data from a new hwdb database, so that old
534 yogas can be recognized as "convertible" too, even if they predate the DMI
535 "convertible" form factor
536
d543b9f5
LP
537* Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
538 after all. Be strict however, only support the equivalent of nspawn's
539 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
540 as MAINPID.
541
f59d1da8
LP
542* Add ExecMonitor= setting. May be used multiple times. Forks off a process in
543 the service cgroup, which is supposed to monitor the service, and when it
544 exits the service is considered failed by its monitor.
545
33bac67b
LP
546* track the per-service PAM process properly (i.e. as an additional control
547 process), so that it may be queried on the bus and everything.
548
549* add a new "debug" job mode, that is propagated to unit_start() and for
550 services results in two things: we raise SIGSTOP right before invoking
551 execve() and turn off watchdog support. Then, use that to implement
552 "systemd-gdb" for attaching to the start-up of any system service in its
553 natural habitat.
554
8eb7383b
LP
555* gpt-auto logic: related to the above, maybe support a "secondary" root
556 partition, that is mounted to / and is writable, and where the actual root's
557 /usr is mounted into.
558
8eb7383b
LP
559* 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
560
67234d21
LP
561* drop nss-myhostname in favour of nss-resolve?
562
b5bdbcd5
LP
563* add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
564 then use that for the setting used in user@.service. It should be understood
565 relative to the configured default value.
566
d21494ea
LP
567* in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
568
569* enable LockMLOCK to take a percentage value relative to physical memory
570
04397464 571* Permit masking specific netlink APIs with RestrictAddressFamily=
d82047be 572
d82047be
LP
573* nspawn: support that /proc, /sys/, /dev are pre-mounted
574
d82047be
LP
575* define gpt header bits to select volatility mode
576
42d61ded
LP
577* ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
578
04397464 579* ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
42d61ded 580
04397464 581* ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
563a69f4 582
04397464 583* ProtectKeyRing= to take keyring calls away
2c5f2958 584
8ce9b83a 585* RemoveKeyRing= to remove all keyring entries of the specified user
a46eac1b
LP
586
587* ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
588 on PID 1 with the relevant signals, and makes relevant files in /sys and
589 /proc (such as the sysrq stuff) unavailable
590
e40a326c 591* make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
89f193fa 592
6809de5b
LP
593* journalctl: make sure -f ends when the container indicated by -M terminates
594
2c5f2958
LP
595* mount: automatically search for "main" partition of an image has multiple
596 partitions
597
8ce9b83a
LP
598* in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
599 find a way to map the User=/Group= of the service to the right name. This way
600 a user/group for a service only has to exist on the host for the right
601 mapping to work.
602
2c5f2958
LP
603* add bus API for creating unit files in /etc, reusing the code for transient units
604
605* add bus API to remove unit files from /etc
606
607* add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
608
b8c7afdf
LP
609* rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
610 kernel doesn't support linkat() that replaces existing files, currently)
611
1e555cb5
LP
612* transient units: don't bother with actually setting unit properties, we
613 reload the unit file anyway
614
1e555cb5
LP
615* journald: sigbus API via a signal-handler safe function that people may call
616 from the SIGBUS handler
617
c8048350
LP
618* optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
619
648b1220
LP
620* delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
621 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
622
3d39e6e5
LP
623* cache sd_event_now() result from before the first iteration...
624
bd098bce
LP
625* PID1: find a way how we can reload unit file configuration for
626 specific units only, without reloading the whole of systemd
627
f9bf1b8f 628* add an explicit parser for LimitRTPRIO= that verifies
de7399eb 629 the specified range and generates sane error messages for incorrect
f9bf1b8f 630 specifications.
de7399eb 631
3efc8c72
LP
632* when we detect that there are waiting jobs but no running jobs, do something
633
5ebbb45b 634* push CPUAffinity= also into the "cpuset" cgroup controller
03364e47 635
e6a26d8c
LP
636* PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
637
a2088fd0 638* there's probably something wrong with having user mounts below /sys,
5238e957 639 as we have for debugfs. for example, src/core/mount.c handles mounts
a2088fd0
LP
640 prefixed with /sys generally special.
641 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html

8aa20381
LP
643* fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
644
b18d23d7
LP
645* docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
646
60d17b74
LP
647* add a job mode that will fail if a transaction would mean stopping
648 running units. Use this in timedated to manage the NTP service
649 state.
650 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
651
477e75ef
LP
652* The udev blkid built-in should expose a property that reflects
653 whether media was sensed in USB CF/SD card readers. This should then
654 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
655 picked up by systemd unless they contain a medium. This would mirror
656 the behaviour we already have for CD drives.
657
2bc39683
LP
658* networkd/udev: implement SR_IOV configuration in .link files:
659 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
660
c3a0d00d

LP
663* Find a solution for SMACK capabilities stuff:
664 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
98cd2651 665
2a441c8a
LP
666* "systemctl preset-all" should probably order the unit files it
667 operates on lexicographically before starting to work, in order to
668 ensure deterministic behaviour if two unit files conflict (like DMs
669 do, for example)
670
0a86c1a9
LP
671* synchronize console access with BSD locks:
672 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
673
e031c227 674* as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
0a86c1a9
LP
675 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
676
8514b677
LP
677* figure out when we can use the coarse timers
678
7b0fce61
LP
679* add "systemctl start -v foobar.service" that shows logs of a service
680 while the start command runs. This is non-trivial to do without
681 races though, since we should flush out all journal messages before
682 returning from the "systemctl stop".
683
b568ef14 684* 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 685
d48b7bd2
LP
686* maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
687
8483d73f
LP
688* maybe allow timer units with an empty Units= setting, so that they
689 can be used for resuming the system but nothing else.
690
25e773ee 691* what to do about udev db binary stability for apps? (raw access is not an option)
b857e042 692
279f0366 693* systemctl: if some operation fails, show log output?
533bb267 694
5238e957 695* systemctl edit: use equivalent of cat() to insert existing config as a comment, prepended with #.
b42de08a 696 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
202aea45 697
720652b3 698* exponential backoff in timesyncd when we cannot reach a server
42aeb14a 699
720652b3 700* timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM

ccc3e8a1
LP
709 - service registration

0f47ed0a 711 - avahi compat
9d6db739 712 - DNS-SD service registration from socket units
e25b5a8d
DH
713 - resolved should optionally register additional per-interface LLMNR
714 names, so that for the container case we can establish the same name
715 (maybe "host") for referencing the server, everywhere.
720652b3 716 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
3efb871a 717 - hook up resolved with machined-based address resolution
3f77a1b1 718
e25b5a8d 719* refcounting in sd-resolve is borked

a01647e5 725* support empty /etc boots nicely:
3c779fa5 726 - nspawn/gpt-generator: introduce new gpt partition type for /usr
a01647e5 727
3de03738
LP
728* generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
729
37efac5d

730* a way for container managers to turn off getty starting via $container_headless= or so...

7348b3ad
LP
732* figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
733
81429136
KS
734* For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
735 they run added to the initial transaction and thus confuse Type=idle.
e107ed18 736
edb2935c
LP
737* add bus api to query unit file's X fields.
738
6a3f892a 739* gpt-auto-generator:
2a781fc9 740 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
6a3f892a 741 - Make /home automount rather than mount?
6a3f892a 742
65026403
LP
743* add generator that pulls in systemd-network from containers when
744 CAP_NET_ADMIN is set, more than the loopback device is defined, even
745 when it is otherwise off
f8901862 746
f9bf1b8f 747* MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
eda8f067 748
af1082b0
LP
749* implement Distribute= in socket units to allow running multiple
750 service instances processing the listening socket, and open this up
751 for ReusePort=
752
09ecd746
LP
753* introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
754 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
755 should SIGSTOP all unit processes in a loop until all processes of
756 it are fully stopped. This can later be used for app management by
757 desktop UIs such as gnome-shell to freeze apps that are not visible
758 on screen, not unlike how job control works on the shell
759
f38afcd0 760* cgroups:
f38afcd0 761 - implement per-slice CPUFairScheduling=1 switch
f38afcd0
LP
762 - introduce high-level settings for RT budget, swappiness
763 - how to reset dynamically changed unit cgroup attributes sanely?
764 - when reloading configuration, apply new cgroup configuration
765 - when recursively showing the cgroup hierarchy, optionally also show
766 the hierarchies of child processes
0bee65f0 767
f38afcd0 768* transient units:
f38afcd0 769 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
ebcf1f97 770
718db961
LP
771* when we detect low battery and no AC on boot, show pretty splash and refuse boot
772
718db961
LP
773* libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
774

775* be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
776
41644622
LP
777* 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

7f79cd71 779* After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
0aafd43d 780

781* If we try to find a unit via a dangling symlink, generate a clean
782 error. Currently, we just ignore it and read the unit from the search
df5f6971
LP
783 path anyway.
784
04397464 785* refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
fcba531e 786
bdeeb6b5
LP
787* man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.

6bb648a1 791* sd-bus:
0d43ffef 792 - EBADSLT handling
fa607802 793 - GetAllProperties() on a non-existing object does not result in a failure currently
7212c608 794 - port to sd-resolve for connecting to TCP dbus servers
57f2a947 795 - 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 796 - see if we can drop more message validation on the sending side
f38afcd0 797 - add API to clone sd_bus_message objects
ab9716c2 798 - longer term: priority inheritance
df98a87b 799 - dbus spec updates:
df98a87b
LP
800 - NameLost/NameAcquired obsolete
801 - GVariant
2ecfc64e 802 - path escaping
6a8b5fa4 803 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
f38afcd0
LP
804
805* sd-event
12179984 806 - allow multiple signal handlers per signal?
0536ce5d 807 - document chaining of signal handler for SIGCHLD and child handlers
e25b5a8d 808 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
eb01ba5d 809
69af4503 810* investigate endianness issues of UUID vs. GUID
e8a7a315 811
461bd8e4
LP
812* dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
813 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
814
ab8e074c
LP
815* add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
816
817* add a pam module that on password changes updates any LUKS slot where the password matches
818
fff87a35 819* test/:
20d52ab6 820 - add unit tests for config_parse_device_allow()
b8b4d3dd 821
b5c03638 822* seems that when we follow symlinks to units we prefer the symlink
d28315e4 823 destination path over /etc and /usr. We should not do that. Instead
b5c03638
LP
824 /etc should always override /run+/usr and also any symlink
825 destination.
826
eece8c6f
LP
827* when isolating, try to figure out a way how we implicitly can order
828 all units we stop before the isolating unit...
829
356ce991
LP
830* teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
831
6daebf9e
ZJS
832* Add ConditionDirectoryNotEmpty= handle non-absoute paths as a search path or add
833 ConditionConfigSearchPathNotEmpty= or different syntax? See the discussion starting at
834 https://github.com/systemd/systemd/pull/15109#issuecomment-607740136.
835
c1446921
LP
836* BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
837 that the boot loader should be installed to the ESP. Define a way
838 how an installer can figure out whether a BLS compliant boot loader
839 is installed.
795607b2 840
0be8342c
LP
841* think about requeuing jobs when daemon-reload is issued? usecase:
842 the initrd issues a reload after fstab from the host is accessible
843 and we might want to requeue the mounts local-fs acquired through
844 that automatically.
845
e5ec62c5 846* systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
54c31a79 847
ccddd104 848* remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
826872b6 849
3679d112
LP
850* shutdown logging: store to EFI var, and store to USB stick?
851
356ce991 852* merge unit_kill_common() and unit_kill_context()
490b7e47 853
b44be3ec 854* EFI:
b44be3ec
LP
855 - honor language efi variables for default language selection (if there are any?)
856 - honor timezone efi variables for default timezone selection (if there are any?)
466784c8 857 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
631427d6 858* bootctl
631427d6 859 - recognize the case when not booted on EFI
e4181484 860
c0fe5db5 861* maybe do not install getty@tty1.service symlink in /etc but in /usr?
e9fd44b7 862
b44be3ec 863* print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
8ed20651 864
b44be3ec 865* mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
e6c6e7af 866
b44be3ec
LP
867* logind:
868 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
b44be3ec
LP
869 - logind: wakelock/opportunistic suspend support
870 - Add pretty name for seats in logind
871 - logind: allow showing logout dialog from system?
f38afcd0
LP
872 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
873 - if pam_systemd is invoked by su from a process that is outside of a
874 any session we should probably just become a NOP, since that's
875 usually not a real user session but just some system code that just
876 needs setuid().
279f0366
LP
877 - logind: make the Suspend()/Hibernate() bus calls wait for the for
878 the job to be completed. before returning, so that clients can wait
879 for "systemctl suspend" to finish to know when the suspending is
880 complete.
881 - logind: when the power button is pressed short, just popup a
882 logout dialog. If it is pressed for 1s, do the usual
883 shutdown. Inspiration are Macs here.
279f0366 884 - expose "Locked" property on logind sesison objects
e25b5a8d
DH
885 - maybe allow configuration of the StopTimeout for session scopes
886 - rename session scope so that it includes the UID. THat way
887 the session scope can be arranged freely in slices and we don't have
888 make assumptions about their slice anymore.
889 - follow PropertiesChanged state more closely, to deal with quick logouts and
890 relogins
77b19caf 891 - (optionally?) spawn seat-manager@$SEAT.service whenever a seat shows up that as CanGraphical set
e673ad04 892
b44be3ec 893* journal:
57f2a947 894 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
b44be3ec
LP
895 - journald: also get thread ID from client, plus thread name
896 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
897 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
d28315e4 898 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
b44be3ec 899 - declare the local journal protocol stable in the wiki interface chart
b44be3ec
LP
900 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
901 - journald: when dropping msgs due to ratelimit make sure to write
902 "dropped %u messages" not only when we are about to print the next
5238e957 903 message that works, but already after a short timeout
b44be3ec
LP
904 - check if we can make journalctl by default use --follow mode inside of less if called without args?
905 - maybe add API to send pairs of iovecs via sd_journal_send
f47ec8eb 906 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
b44be3ec
LP
907 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
908 and !FOOBAR for events without FOOBAR.
038cf334
ZJS
909 - journal: store timestamp of journal_file_set_offline() int he header,
910 so it is possible to display when the file was last synced.
b44be3ec
LP
911 - 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.
912 - journal: find a way to allow dropping history early, based on priority, other rules
913 - journal: When used on NFS, check payload hashes
b44be3ec
LP
914 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
915 - refuse taking lower-case variable names in sd_journal_send() and friends.
916 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
917 - journal: deal nicely with byte-by-byte copied files, especially regards header
b44be3ec 918 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
601d9d6f 919 - Replace utmp, wtmp, btmp, and lastlog completely with journal
f38afcd0 920 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
f38afcd0
LP
921 - when a kernel driver logs in a tight loop, we should ratelimit that too.
922 - journald: optionally, log debug messages to /run but everything else to /var
923 - journald: when we drop syslog messages because the syslog socket is
924 full, make sure to write how many messages are lost as first thing
925 to syslog when it works again.
279f0366
LP
926 - journald: allow per-priority and per-service retention times when rotating/vacuuming
927 - journald: make use of uid-range.h to managed uid ranges to split
928 journals in.
929 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
930 - improve journalctl performance by loading journal files
931 lazily. Encode just enough information in the file name, so that we
932 do not have to open it to know that it is not interesting for us, for
933 the most common operations.
e25b5a8d 934 - man: document that corrupted journal files is nothing to act on
e25b5a8d
DH
935 - rework journald sigbus stuff to use mutex
936 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
937 services that run under their own user ids, and use User= (but only
938 in a world where userns is ubiquitous since otherwise we cannot
939 invoke those daemons on the host AND in a container anymore). Also,
940 if LimitNPROC= is used without User= we should warn and refuse
941 operation.
942 - journalctl --verify: don't show files that are currently being
943 written to as FAIL, but instead show that their are being written to.
944 - add journalctl -H that talks via ssh to a remote peer and passes through
945 binary logs data
e25b5a8d 946 - add a version of --merge which also merges /var/log/journal/remote
e25b5a8d
DH
947 - journalctl: -m should access container journals directly by enumerating
948 them via machined, and also watch containers coming and going.
949 Benefit: nspawn --ephemeral would start working nicely with the journal.
950 - assign MESSAGE_ID to log messages about failed services
b44be3ec 951
590171d1
ZJS
952* add a test if all entries in the catalog are properly formatted.
953 (Adding dashes in a catalog entry currently results in the catalog entry
954 being silently skipped. journalctl --update-catalog must warn about this,
955 and we should also have a unit test to check that all our message are OK.)
956
b44be3ec 957* document:
8b8f2591 958 - document that deps in [Unit] sections ignore Alias= fields in
b44be3ec
LP
959 [Install] units of other units, unless those units are disabled
960 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
b44be3ec 961 - document that service reload may be implemented as service reexec
f38afcd0
LP
962 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
963 - document systemd-journal-flush.service properly
f38afcd0
LP
964 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
965 - man: document the very specific env the shutdown drop-in tools live in
f38afcd0
LP
966 - man: add more examples to man pages
967 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
17ec531f 968 - document root=gpt-auto properly
b44be3ec
LP
969
970* systemctl:
b44be3ec
LP
971 - add systemctl switch to dump transaction without executing it
972 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
973 - "systemctl disable" on a static unit prints no message and does
974 nothing. "systemctl enable" does nothing, and gives a bad message
975 about it. Should fix both to print nice actionable messages.
976 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
977 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
d28315e4 978 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
b44be3ec 979 - systemctl: "Journal has been rotated since unit was started." message is misleading
61233823 980 - systemctl status output should include list of triggering units and their status
f38afcd0
LP
981
982* unit install:
983 - "systemctl mask" should find all names by which a unit is accessible
984 (i.e. by scanning for symlinks to it) and link them all to /dev/null
8b04b925 985
b44be3ec 986* timer units:
b44be3ec 987 - timer units should get the ability to trigger when:
b44be3ec 988 o DST changes
90e071d1 989 - Modulate timer frequency based on battery state
d2e83c23 990
a19554ed
LP
991* add libsystemd-password or so to query passwords during boot using the password agent logic
992
a7a3f28b
LP
993* clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
994
b44be3ec 995* on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
08f95888 996
f59d1da8 997* make repeated alt-ctrl-del presses printing a dump
dcfc4b2e 998
71ef24d0
LP
999* hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
1000
d28315e4 1001* currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
1b89884b 1002
b44be3ec 1003* nspawn:
e25b5a8d
DH
1004 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
1005 with seccomp. That should provide us with a useful log buffer that
1006 systemd can log to during early boot, and disconnect container logs
1007 from the kernel's logs.
1008 - as soon as networkd has a bus interface, hook up --network-interface=,
1009 --network-bridge= with networkd, to trigger netdev creation should an
1010 interface be missing
e25b5a8d
DH
1011 - a nice way to boot up without machine id set, so that it is set at boot
1012 automatically for supporting --ephemeral. Maybe hash the host machine id
1013 together with the machine name to generate the machine id for the container
1014 - fix logic always print a final newline on output.
1015 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
1016 - should optionally support receiving WATCHDOG=1 messages from its payload
1017 PID 1...
e25b5a8d
DH
1018 - optionally automatically add FORWARD rules to iptables whenever nspawn is
1019 running, remove them when shut down.
e25b5a8d 1020
347a17d5
ZJS
1021* dissect
1022 - refuse mounting over a mount point
1023 - automatically discover .roothash files in dissect, similarly to nspawn
1024
e25b5a8d 1025* machined:
e25b5a8d
DH
1026 - add an API so that libvirt-lxc can inform us about network interfaces being
1027 removed or added to an existing machine
1028 - "machinectl migrate" or similar to copy a container from or to a
1029 difference host, via ssh
e25b5a8d
DH
1030 - introduce systemd-nspawn-ephemeral@.service, and hook it into
1031 "machinectl start" with a new --ephemeral switch
1032 - "machinectl status" should also show internal logs of the container in
1033 question
e25b5a8d
DH
1034 - "machinectl history"
1035 - "machinectl diff"
1036 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
1037 shell in it, and marks it read-only after use
1038
b44be3ec 1039* cryptsetup:
b44be3ec 1040 - cryptsetup-generator: allow specification of passwords in crypttab itself
5f1dac6b 1041 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
f8019684 1042
424a19f8 1043* hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
41f9172f 1044 https://bugs.freedesktop.org/show_bug.cgi?id=54712
424a19f8 1045
83fefc88
ZJS
1046* add a dependency on standard-conf.xml and other included files to man pages

1052* initialize the hostname from the fs label of /, if /etc/hostname does not exist?
1053
abd55b16 1054* udev:
abd55b16 1055 - move to LGPL
abd55b16
KS
1056 - kill scsi_id
1057 - add trigger --subsystem-match=usb/usb_device device
e8d842a0 1058 - reimport udev db after MOVE events for devices without dev_t
b8217b7b 1059
7f110ff9
LP
1060* There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
1061
d0e5a333
LP
1062* add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
1063
e25b5a8d
DH
1064* coredump:
1065 - save coredump in Windows/Mozilla minidump format
73a99163 1066 - 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
1067
1068* support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)

f957632b
KS
1070* be able to specify a forced restart of service A where service B depends on, in case B
1071 needs to be auto-respawned?
1072
f38afcd0 1073* tmpfiles:
f38afcd0 1074 - apply "x" on "D" too (see patch from William Douglas)
614cc34f 1075 - instead of ignoring unknown fields, reject them.
e25b5a8d
DH
1076 - creating new directories/subvolumes/fifos/device nodes

1078 calls follow symlinks.
1258097c 1079
a4c279f8
LP
1080* make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
1081
f28f1daf
LP
1082* verify that the AF_UNIX sockets of a service in the fs still exist
1083 when we start a service in order to avoid confusion when a user
1084 assumes starting a service is enough to make it accessible
1085
88a07670
LP
1086* Make it possible to set the keymap independently from the font on
1087 the kernel cmdline. Right now setting one resets also the other.
1088
71092d70 1089* and a dbus call to generate target from current state

1111
59fee421
LP
1112* dot output for --test showing the 'initial transaction'
1113
e25b5a8d 1114* pid1:
e25b5a8d
DH
1115 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
1116 log both units as UNIT=, so that journalctl -u triggers on both.
1117 - generate better errors when people try to set transient properties
1118 that are not supported...
1119 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
1120 - maybe introduce WantsMountsFor=? Usecase:
1121 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
1122 - recreate systemd's D-Bus private socket file on SIGUSR2
e25b5a8d
DH
1123 - move PAM code into its own binary
1124 - when we automatically restart a service, ensure we restart its rdeps, too.
e25b5a8d
DH
1125 - hide PAM options in fragment parser when compile time disabled
1126 - Support --test based on current system state
1127 - 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().
1128 - after deserializing sockets in socket.c we should reapply sockopts and things
e25b5a8d
DH
1129 - drop PID 1 reloading, only do reexecing (difficult: Reload()
1130 currently is properly synchronous, Reexec() is weird, because we
1131 cannot delay the response properly until we are back, so instead of
1132 being properly synchronous we just keep open the fd and close it
1133 when done. That means clients do not get a successful method reply,
1134 but much rather a disconnect on success.
1135 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
1136 - when a bus name of a service disappears from the bus make sure to queue further activation requests
1137
1138* unit files:
1139 - allow port=0 in .socket units
1140 - maybe introduce ExecRestartPre=
1141 - add ReloadSignal= for configuring a reload signal to use
1142 - implement Register= switch in .socket units to enable registration

1153* udev-link-config:
1154 - Make sure ID_PATH is always exported and complete for
1155 network devices where possible, so we can safely rely
1156 on Path= matching

e25b5a8d 1171 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
e25b5a8d
DH
1172 - the DHCP lease data (such as NTP/DNS) is still made available when
1173 a carrier is lost on a link. It should be removed instantly.
1174 - expose in the API the following bits:
1175 - option 15, domain name and/or option 119, search list
38b38500 1176 - option 12, hostname and/or option 81, fqdn
e25b5a8d
DH
1177 - option 123, 144, geolocation
1178 - option 252, configure http proxy (PAC/wpad)
1179 - provide a way to define a per-network interface default metric value
1180 for all routes to it. possibly a second default for DHCP routes.
1181 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
1182 support Name=foo*|bar*|baz ?
1183 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
1184 - allow DUID/IAID to be customized, see issue #394.
e25b5a8d 1185 - whenever uplink info changes, make DHCP server send out FORCERENEW

1193* dhcp6:
1194 - add functions to set previously stored IPv6 addresses on startup and get
1195 them at shutdown; store them in client->ia_na
1196 - write more test cases
37d8b536 1197 - implement reconfigure support, see 5.3., 15.11. and 22.20.

37d8b536
PF
1199 - implement dhcpv6 authentication
1200 - investigate the usefulness of Confirm messages; i.e. are there any
1201 situations where the link changes without any loss in carrier detection
1202 or interface down
1203 - some servers don't do rapid commit without a filled in IA_NA, verify
1204 this behavior
