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.
7 * busctl prints errors to stdout:
8 busctl tree org.freedesktop.systemd1 /org/freedesktop/systemd1
12 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
14 * wiki: update journal format documentation for lz4 additions
18 * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
20 * rework mount.c and swap.c to follow proper state enumeration/deserialization
21 semantics, like we do for device.c now
25 * add "throttling" to sd-event event sources: optionally, when we wake up too
26 often for one, let's turn it off entirely for a while. Use that for the
27 /proc/self/mountinfo logic.
29 * move our systemd-user PAM snippet to /usr/, which PAM appears to support
32 * nspawn: support time namespaces
34 * pid1: Move to tracking of main pid/control pid of units per pidfd
36 * pid1: support new clone3() fork-into-cgroup feature
38 * pid1: also remove PID files of a service when the service starts, not just
41 * make "systemd-dissect" an official supported tool, i.e. move to /usr/bin/ and
42 provide man page. Given that we now have a tool that can generate images like
43 this, it's useful to have one that can dump contents of them, too.
45 * All tools that support --root= should also learn --image= so that they can
46 operate on disk images directly. Specifically: bootctl, firstboot, tmpfiles,
47 sysusers, systemctl, repart, journalctl, coredumpctl.
49 * per-service credential system. Specifically: add LoadCredential= (for loading
50 cred from file), AcquireCredential= (for asking user for cred, via
51 ask-password), PassCredential= (for passing on credential systemd itself
52 got). Then, place credentials in a per-service, immutable ramfs instance (so
53 that it cannot be swapped out), destroy after use. Also pass via keyring
54 (with graceful fallback to cover for containers). Define CredentialPath= for
55 defining subdir of /run/credentials/ where to place it. Set $CREDENTIAL_PATH
56 env var for services to the result. Also pass via fd passing (optionally).
58 * homed: add native recovery key support. use 48 lowercase modhex characters
59 (192bit), show qr code of it, include pattern expression in user record.
61 * homed: introduce "degraded" state for home directories that weren't cleanly
62 unmounted (use xattr we add and remove on the loop back file)
64 * homed: during login resize fs automatically towards size goal. Specifically,
65 resize to diskSize if possible, but leave a certain amount (configured by a
66 new value diskLeaveFreeSize) of space free on the backing fs.
68 * homed: permit multiple user record signing keys to be used locally, and pick
69 the right one for signing records automatically depending on a pre-existing
72 * homed: add a way to "adopt" a home directory, i.e. strip foreign signatures
73 and insert a local signature instead.
75 * homed: as an extension to the directory+subvolume backend: if located on
76 especially marked fs, then sync down password into LUKS header of that fs,
77 and always verify passwords against it too. Bootstrapping is a problem
78 though: if noone is logged in (or no other user even exists yet), how do you
79 unlock the volume in order to create the first user and add the first pw.
81 * homed: support new FS_IOC_ADD_ENCRYPTION_KEY ioctl for setting up fscrypt
83 * busctl: maybe expose a verb "ping" for pinging a dbus service to see if it
86 * homed: maybe pre-create ~/.cache as subvol so that it can have separate quota
89 * when systemd-nspawn and suchlike dissect an OS image, and there are multiple
90 root partitions, do an strverscmp() on the partition label and boot
91 first. That is inspired how sd-boot figures out which kernel to boot, and
92 thus allows defining OS images which can be A/B updated and we default to the
93 newest version automatically, both in nspawn and in sd-boot
95 * cryptsetup/homed: also support FIDO2 HMAC password logic for unlocking
96 devices. (see: https://github.com/mjec/fido2-hmac-secret)
98 * systemd-gpt-auto should probably set x-systemd.growfs on the mounts it
101 * homed/userdb: distinguish passwords and recovery keys in the records, since
102 we probably want to use different PBKDF algorithms/settings for them:
103 passwords have low entropy but recovery keys should have good entropy key
104 hence we can make them quicker to work.
107 - teach it to prepare an ESP wholesale, i.e. with mkfs.vfat invocation
108 - teach it to copy in unified kernel images and maybe type #1 boot loader spec entries from host
109 - make it operate on loopback files, dissecting enough to find ESP to operate on
111 * by default, in systemd --user service bump the OOMAdjust to 100, as privs
112 allow so that systemd survives
114 * cryptsetup: allow encoding key directly in /etc/crypttab, maybe with a
115 "base64:" prefix. Useful in particular for pkcs11 mode.
117 * cryptsetup: reimplement the mkswap/mke2fs in cryptsetup-generator to use
118 systemd-makefs.service instead.
120 * socket units: allow creating a udev monitor socket with ListenDevices= or so,
121 with matches, then activate app through that passing socket over
124 - port sd_id128_get_machine_app_specific() over from khash
125 - port resolved over from libgcrypt (DNSSEC code)
126 - port journald + fsprg over from libgcrypt
127 - port importd over from libgcrypt
128 - when that's done: kill khash.c
129 - when that's done: kill gnutls support in resolved
131 * kill zenata, all hail weblate?
133 * when we resize disks (homed?) always round up to 4K sectors, not 512K
135 * add growvol and makevol options for /etc/crypttab, similar to
136 x-systemd.growfs and x-systemd-makefs.
138 * hook up the TPM to /etc/crypttab, with a new option that is similar to the
139 new PKCS#11 option in crypttab, and allows unlocking a LUKS volume via a key
140 unsealed from the TPM. Optionally, if TPM is not available fall back to
141 TPM-less mode, and set up linear DM mapping instead (inspired by kpartx), so
142 that the device paths stay the same, regardless if crypto is used or not.
144 * systemd-repart: by default generate minimized partition tables (i.e. tables
145 that only cover the space actually used, excluding any free space at the
146 end), in order to maximize dd'ability. Requires libfdisk work, see
147 https://github.com/karelzak/util-linux/issues/907
149 * systemd-repart: optionally, allow specifying a path to initialize new
150 partitions from, i.e. an fs image file or a source device node. This would
151 then turn systemd-repart into a simple installer: with a few .repart files
152 you could replicate the host system on another device. a full installer would
153 then be: "systemd-repart /dev/sda && bootctl install /dev/sda &&
154 systemd-firstboot --image= …"
156 * systemd-repart: MBR partition table support. Care needs to be taken regarding
157 Type=, so that partition definitions can sanely apply to both the GPT and the
158 MBR case. Idea: accept syntax "Type=gpt:home mbr:0x83" for setting the types
159 for the two partition types explicitly. And provide an internal mapping so
160 that "Type=linux-generic" maps to the right types for both partition tables
163 * systemd-repart: allow sizing partitions as factor of available RAM, so that
164 we can reasonably size swap partitions for hibernation.
166 * systemd-repart: allow running mkfs before making partitions pop up +
167 encryption via LUKS to allow booting into an empty root with only /usr mounted in
169 * systemd-repart: allow managing the gpt read-only partition flag + auto-mount flag
171 * systemd-repart: allow disabling growing of specific partitions, or making
172 them (think ESP: we don't ever want to grow it, since we cannot resize vfat)
174 * systemd-repart: add specifier expansion, add especifier that refers to root
175 device node of current system, /usr device node, and matching verity, so that
176 an installer can be made a "copy" installer of the booted OS
178 * systemd-repart: make it a static checker during early boot for existence and
179 absence of other partitions for trusted boot environments
181 * systemd-repart: allow config of partition uuid
183 * userdb: allow username prefix searches in varlink API, allow realname and
184 realname substr searches in varlink API
186 * userdb: allow uid/gid range checks
188 * userdb: allow existence checks
190 * pid1: activation by journal search expression
192 * when switching root from initrd to host, set the machine_id env var so that
193 if the host has no machine ID set yet we continue to use the random one the
196 * sd-event: add native support for P_ALL waitid() watching, then move PID 1 to
197 it fo reaping assigned but unknown children. This needs to some special care
198 to operate somewhat sensibly in light of priorities: P_ALL will return
199 arbitrary processes, regardless of the priority we want to watch them with,
200 hence on each event loop iteration check all processes which we shall watch
201 with higher prio explicitly, and then watch the entire rest with P_ALL.
203 * tweak sd-event's child watching: keep a prioq of children to watch and use
204 waitid() only on the children with the highest priority until one is waitable
205 and ignore all lower-prio ones from that point on
207 * maybe introduce xattrs that can be set on the root dir of the root fs
208 partition that declare the volatility mode to use the image in. Previously I
209 thought marking this via GPT partition flags but that's not ideal since
210 that's outside of the LUKS encryption/verity verification, and we probably
211 shouldn't operate in a volatile mode unless we got told so from a trusted
214 * figure out automatic partition discovery when combining writable root dir
217 * coredump: maybe when coredumping read a new xattr from /proc/$PID/exe that
218 may be used to mark a whole binary as non-coredumpable. Would fix:
219 https://bugs.freedesktop.org/show_bug.cgi?id=69447
221 * teach parse_timestamp() timezones like the calendar spec already knows it
223 * beef up hibernation to optionally do swapon/swapoff immediately before/after
226 * beef up s2h to implement a battery watch loop: instead of entering
227 hibernation unconditionally after coming back from resume make a decision
228 based on the battery load level: if battery level is above a specific
229 threshold, go to suspend again, only hibernate if below it. This means we'd
230 stick to suspend usually, but fall back to hibernation only when battery runs
231 empty (well, subject to our sampling interval). Related to this, check if we
232 can make ACPI _BTP (i.e. /sys/class/power_supply/*/alarm) work for us too,
233 i.e. see if it can wake up machines from suspend, so that we could resume
234 automatically when the system is low on power and move automatically to
235 hibernation mode. (see
236 https://uefi.org/sites/default/files/resources/ACPI%206_2_A_Sept29.pdf
238 https://docs.microsoft.com/en-us/windows-hardware/design/device-experiences/modern-standby-wake-sources
241 * add an explicit "vertical" mode to format-table, so that "systemctl
242 status"-like outputs (i.e. with a series of field names left and values
243 right) become genuine first class citizens, and we gain automatic, sane JSON
246 * systemd-firstboot: teach it dissector magic, so that you can point it to some
247 disk image and it will just set everything in it all behind the scenes.
249 * systemd-firstboot: add --force mode that replaces existing configuration.
251 * We should probably replace /var/log/README, /etc/rc.d/README with symlinks
252 that are linked to these places instead of copied. After all they are
253 constant vendor data.
255 * maybe add kernel cmdline params: 1) to force first-boot mode + 2) to force
256 random seed crediting
258 * nspawn: on cgroupsv1 issue cgroup empty handler process based on host events,
259 so that we make cgroup agent logic safe
261 * nspawn/machined: add API to invoke binary in container, then use that as
262 fallback in "machinectl shell"
264 * logind: rework pam_logind to also do a bus call in case of invocation from
265 user@.service, which returns the XDG_RUNTIME_DIR value, and make this
266 behaviour selectable via pam module option.
269 - when user tries to log into record signed by unrecognized key, automatically add key to our chain after polkit auth
270 - hook up machined/nspawn users with a varlink user query interface
271 - rollback when resize fails mid-operation
272 - GNOME's side for forget key on suspend (requires rework so that lock screen runs outside of uid)
274 - shrink fs on logout?
275 - update LUKS password on login if we find there's a password that unlocks the JSON record but not the LUKS device.
276 - create on activate?
277 - properties: icon url?, preferred session type?, administrator bool (which translates to 'wheel' membership)?, address?, telephone?, vcard?, samba stuff?, parental controls?
278 - communicate clearly when usb stick is safe to remove. probably involves
279 beefing up logind to make pam session close hook synchronous and wait until
280 systemd --user is shut down.
281 - logind: maybe keep a "busy fd" as long as there's a non-released session around or the user@.service
282 - maybe make automatic, read-only, time-based reflink-copies of LUKS disk images (think: time machine)
283 - distinguish destroy / remove (i.e. currently we can unregister a user, unregister+remove their home directory, but not just remove their home directory)
284 - in systemd's PAMName= logic: query passwords with ssh-askpassword, so that we can make "loginctl set-linger" mode work
285 - fingerprint authentication, pattern authentication, …
286 - make sure "classic" user records can also be managed by homed
287 - description field for groups
288 - make size of $XDG_RUNTIME_DIR configurable in user record
289 - reuse pwquality magic in firstboot
290 - query password from kernel keyring first
291 - update even if record is "absent"
292 - add a "access mode" + "fstype" field to the "status" section of json identity records reflecting the actually used access mode and fstype, even on non-luks backends
293 - move acct mgmt stuff from pam_systemd_home to pam_systemd?
294 - when "homectl --pkcs11-token-uri=" is used, synthesize ssh-authorized-keys records for all keys we have private keys on the stick for
295 - make slice for users configurable (requires logind rework)
296 - logind: populate auto-login list bus property from PKCS#11 token
297 - when determining state of a LUKS home directory, check DM suspended sysfs file
299 * introduce a new per-process uuid, similar to the boot id, the machine id, the
300 invocation id, that is derived from process creds, specifically a hashed
301 combination of AT_RANDOM + getpid() + the starttime from
302 /proc/self/status. Then add these ids implicitly when logging. Deriving this
303 uuid from these three things has the benefit that it can be derived easily
304 from /proc/$PID/ in a stable, and unique way that changes on both fork() and
307 * let's not GC a unit while its ratelimits are still pending
309 * when killing due to service watchdog timeout maybe detect whether target
310 process is under ptracing and then log loudly and continue instead.
312 * introduce a new group to own TPM devices
314 * make rfkill uaccess controllable by default, i.e. steal rule from
315 gnome-bluetooth and friends
317 * tweak journald context caching. In addition to caching per-process attributes
318 keyed by PID, cache per-cgroup attributes (i.e. the various xattrs we read)
319 keyed by cgroup path, and guarded by ctime changes. This should provide us
320 with a nice speed-up on services that have many processes running in the same
323 * make MAINPID= message reception checks even stricter: if service uses User=,
324 then check sending UID and ignore message if it doesn't match the user or
327 * maybe trigger a uevent "change" on a device if "systemctl reload xyz.device"
330 * when importing an fs tree with machined, optionally apply userns-rec-chown
332 * when importing an fs tree with machined, complain if image is not an OS
334 * Maybe introduce a helper safe_exec() or so, which is to execve() which
335 safe_fork() is to fork(). And then make revert the RLIMIT_NOFILE soft limit
336 to 1K implicitly, unless explicitly opted-out.
338 * rework seccomp/nnp logic that even if User= is used in combination with
339 a seccomp option we don't have to set NNP. For that, change uid first whil
340 keeping CAP_SYS_ADMIN, then apply seccomp, the drop cap.
342 * add a concept for automatically loading per-unit secrets off disk and
343 inserting them into the kernel keyring. Maybe SecretsDirectory= similar to
344 ConfigurationDirectory=.
346 * when no locale is configured, default to UEFI's PlatformLang variable
348 * bootctl,sd-boot: actually honour the "architecture" key
350 * add a new syscall group "@esoteric" for more esoteric stuff such as bpf() and
351 usefaultd() and make systemd-analyze check for it.
353 * paranoia: whenever we process passwords, call mlock() on the memory
354 first. i.e. look for all places we use free_and_erasep() and
355 augment them with mlock(). Also use MADV_DONTDUMP.
357 * Move RestrictAddressFamily= to the new cgroup create socket
359 * support the bind/connect/sendmsg cgroup stuff for sandboxing, and possibly
362 * maybe implicitly attach monotonic+realtime timestamps to outgoing messages in
363 log.c and sd-journal-send
365 * optionally: turn on cgroup delegation for per-session scope units
367 * introduce per-unit (i.e. per-slice, per-service) journal log size limits.
369 * sd-boot: automatically load EFI modules from some drop-in dir, so that people
370 can add in file system drivers and such
372 * sd-boot: optionally, show boot menu when previous default boot item has
373 non-zero "tries done" count
375 * introduce an option (or replacement) for "systemctl show" that outputs all
376 properties as JSON, similar to busctl's new JSON output. In contrast to that
377 it should skip the variant type string though.
379 * augment CODE_FILE=, CODE_LINE= with something like CODE_BASE= or so which
380 contains some identifier for the project, which allows us to include
381 clickable links to source files generating these log messages. The identifier
382 could be some abberviated URL prefix or so (taking inspiration from Go
383 imports). For example, for systemd we could use
384 CODE_BASE=github.com/systemd/systemd/blob/98b0b1123cc or so which is
385 sufficient to build a link by prefixing "http://" and suffixing the
388 * Augment MESSAGE_ID with MESSAGE_BASE, in a similar fashion so that we can
389 make clickable links from log messages carrying a MESSAGE_ID, that lead to
390 some explanatory text online.
392 * maybe extend .path units to expose fanotify() per-mount change events
394 * Add a "systemctl list-units --by-slice" mode or so, which rearranges the
395 output of "systemctl list-units" slightly by showing the tree structure of
396 the slices, and the units attached to them.
398 * the a-posteriori stopping of units bound to units that disappeared logic
399 should be reworked: there should be a queue of units, and we should only
400 enqueue stop jobs from a defer event that processes queue instead of
401 right-away when we find a unit that is bound to one that doesn't exist
402 anymore. (similar to how the stop-unneeded queue has been reworked the same
405 * nspawn: make nspawn suitable for shell pipelines: instead of triggering a
406 hangup when input is finished, send ^D, which synthesizes an EOF. Then wait
407 for hangup or ^D before passing on the EOF.
409 * When reloading configuration PID 1 should reset all its properties to the
410 original defaults before calling parse_config()
412 * nspawn: greater control over selinux label?
414 * hibernate/s2h: make this robust and safe to enable in Fedora by default.
417 1. add resume_offset support to the resume code (i.e. support swap files
419 2. check if swap is on weird storage and refuse if so
420 3. add auto-detection of hibernation images
422 * cgroups: use inotify to get notified when somebody else modifies cgroups
423 owned by us, then log a friendly warning.
425 * beef up log.c with support for stripping ANSI sequences from strings, so that
426 it is OK to include them in log strings. This would be particularly useful so
427 that our log messages could contain clickable links for example for unit
428 files and suchlike we operate on.
430 * add support for "portablectl attach http://foobar.com/waaa.raw (i.e. importd integration)
432 * add attach --enable and attach --now (for attach+enable+start)
434 * sync dynamic uids/gids between host+portable srvice (i.e. if DynamicUser=1 is set for a service, make sure that the
435 selected user is resolvable in the service even if it ships its own /etc/passwd)
437 * Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the
438 other doesn't. What a disaster. Probably to exclude it. Also
439 DECIMAL_STR_WIDTH should probably add an extra "-" into account for negative
442 * Check that users of inotify's IN_DELETE_SELF flag are using it properly, as
443 usually IN_ATTRIB is the right way to watch deleted files, as the former only
444 fires when a file is actually removed from disk, i.e. the link count drops to
445 zero and is not open anymore, while the latter happens when a file is
446 unlinked from any dir.
448 * port systemctl, busctl, … over to format-table.[ch]'s table formatters
450 * pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up
452 * add --vacuum-xyz options to coredumpctl, matching those journalctl already has.
454 * introduce Ephemeral= unit file switch, that creates an ephemeral copy of all
455 files and directories that are left writable for a unit, and which are
456 removed after the unit goes down again. A bit like --ephemeral for
457 systemd-nspawn but for system services. If used together with RootImage= this
458 should reflink the image file itself.
460 Related: add Ephemeral=<path1> <path2> … which would allow marking
461 specific paths only like this.
463 * add CopyFile= or so as unit file setting that may be used to copy files or
464 directory trees from the host to the services RootImage= and RootDirectory=
465 environment. Which we can use for /etc/machine-id and in particular
466 /etc/resolv.conf. Should be smart and do something useful on read-only
467 images, for example fallback to read-only bind mounting the file instead.
469 * show invocation ID in systemd-run output
471 * bypass SIGTERM state in unit files if KillSignal is SIGKILL
473 * add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1
474 and so on, which would mean we could report errors and such.
476 * teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4
479 * introduce DefaultSlice= or so in system.conf that allows changing where we
480 place our units by default, i.e. change system.slice to something
481 else. Similar, ManagerSlice= should exist so that PID1's own scope unit could
482 be moved somewhere else too. Finally machined and logind should get similar
483 options so that it is possible to move user session scopes and machines to a
484 different slice too by default. Usecase: people who want to put resources on
485 the entire system, with the exception of one specific service. See:
486 https://lists.freedesktop.org/archives/systemd-devel/2018-February/040369.html
488 * maybe rework get_user_creds() to query the user database if $SHELL is used
489 for root, but only then.
491 * be stricter with fds we receive for the fdstore: close them asynchronously
493 * calenderspec: add support for week numbers and day numbers within a
494 year. This would allow us to define "bi-weekly" triggers safely.
496 * sd-bus: add vtable flag, that may be used to request client creds implicitly
497 and asynchronously before dispatching the operation
499 * make use of ethtool veth peer info in machined, for automatically finding out
500 host-side interface pointing to the container.
502 * add some special mode to LogsDirectory=/StateDirectory=… that allows
503 declaring these directories without necessarily pulling in deps for them, or
504 creating them when starting up. That way, we could declare that
505 systemd-journald writes to /var/log/journal, which could be useful when we
506 doing disk usage calculations and so on.
508 * taint systemd if there are fewer than 65536 users assigned (userns) to the system.
510 * deprecate RootDirectoryStartOnly= in favour of a new ExecStart= prefix char
512 * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
513 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
514 as the unit is running or has a job queued.
516 * support projid-based quota in machinectl for containers
518 * add a way to lock down cgroup migration: a boolean, which when set for a unit
519 makes sure the processes in it can never migrate out of it
521 * blog about fd store and restartable services
523 * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
525 * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
526 magic meaning and is no longer upgraded to something else if set explicitly.
528 * in the long run: permit a system with /etc/machine-id linked to /dev/null, to
529 make it lose its identity, i.e. be anonymous. For this we'd have to patch
530 through the whole tree to make all code deal with the case where no machine
533 * optionally, collect cgroup resource data, and store it in per-unit RRD files,
534 suitable for processing with rrdtool. Add bus API to access this data, and
535 possibly implement a CPULoad property based on it.
537 * beef up pam_systemd to take unit file settings such as cgroups properties as
540 * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
541 the quota of a the user indicated in User= via unit file settings, like the
542 other resource management concepts. Would mix nicely with DynamicUser=1. Or
543 alternatively, do this with projids, so that we can also cover services
544 running as root. Quota should probably cover all the special dirs such as
545 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
546 is set, plus the whole disk space any image configured with RootImage=.
548 * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
549 disks to see if the UID is already in use.
551 * add "systemctl wait" or so, which does what "systemd-run --wait" does, but
552 for all units. It should be both a way to pin units into memory as well as a
553 wait to retrieve their exit data.
555 * expose IO accounting data on the bus, show it in systemd-run --wait and log
556 about it in the resource log message
558 * show whether a service has out-of-date configuration in "systemctl status" by
559 using mtime data of ConfigurationDirectory=.
561 * Add AddUser= setting to unit files, similar to DynamicUser=1 which however
562 creates a static, persistent user rather than a dynamic, transient user. We
563 can leverage code from sysusers.d for this.
565 * add some optional flag to ReadWritePaths= and friends, that has the effect
566 that we create the dir in question when the service is started. Example:
568 ReadWritePaths=:/var/lib/foobar
570 * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
571 the sd-journal logging socket, and, if the timeout is set to 0, sets
572 O_NONBLOCK on it. That way people can control if and when to block for
575 * hostnamed: populate form factor data from a new hwdb database, so that old
576 yogas can be recognized as "convertible" too, even if they predate the DMI
577 "convertible" form factor
579 * Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
580 after all. Be strict however, only support the equivalent of nspawn's
581 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
584 * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
585 the service cgroup, which is supposed to monitor the service, and when it
586 exits the service is considered failed by its monitor.
588 * track the per-service PAM process properly (i.e. as an additional control
589 process), so that it may be queried on the bus and everything.
591 * add a new "debug" job mode, that is propagated to unit_start() and for
592 services results in two things: we raise SIGSTOP right before invoking
593 execve() and turn off watchdog support. Then, use that to implement
594 "systemd-gdb" for attaching to the start-up of any system service in its
597 * gpt-auto logic: related to the above, maybe support a "secondary" root
598 partition, that is mounted to / and is writable, and where the actual root's
599 /usr is mounted into.
601 * 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
603 * drop nss-myhostname in favour of nss-resolve?
605 * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
606 then use that for the setting used in user@.service. It should be understood
607 relative to the configured default value.
609 * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
611 * enable LockMLOCK to take a percentage value relative to physical memory
613 * Permit masking specific netlink APIs with RestrictAddressFamily=
615 * nspawn: support that /proc, /sys/, /dev are pre-mounted
617 * define gpt header bits to select volatility mode
619 * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
621 * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
623 * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
625 * ProtectKeyRing= to take keyring calls away
627 * RemoveKeyRing= to remove all keyring entries of the specified user
629 * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
630 on PID 1 with the relevant signals, and makes relevant files in /sys and
631 /proc (such as the sysrq stuff) unavailable
633 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
635 * journalctl: make sure -f ends when the container indicated by -M terminates
637 * mount: automatically search for "main" partition of an image has multiple
640 * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
641 find a way to map the User=/Group= of the service to the right name. This way
642 a user/group for a service only has to exist on the host for the right
645 * add bus API for creating unit files in /etc, reusing the code for transient units
647 * add bus API to remove unit files from /etc
649 * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
651 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
652 kernel doesn't support linkat() that replaces existing files, currently)
654 * transient units: don't bother with actually setting unit properties, we
655 reload the unit file anyway
657 * journald: sigbus API via a signal-handler safe function that people may call
658 from the SIGBUS handler
660 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
662 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
663 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
665 * cache sd_event_now() result from before the first iteration...
667 * PID1: find a way how we can reload unit file configuration for
668 specific units only, without reloading the whole of systemd
670 * add an explicit parser for LimitRTPRIO= that verifies
671 the specified range and generates sane error messages for incorrect
674 * when we detect that there are waiting jobs but no running jobs, do something
676 * push CPUAffinity= also into the "cpuset" cgroup controller
678 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
680 * there's probably something wrong with having user mounts below /sys,
681 as we have for debugfs. for example, src/core/mount.c handles mounts
682 prefixed with /sys generally special.
683 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
685 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
687 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
689 * add a job mode that will fail if a transaction would mean stopping
690 running units. Use this in timedated to manage the NTP service
692 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
694 * The udev blkid built-in should expose a property that reflects
695 whether media was sensed in USB CF/SD card readers. This should then
696 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
697 picked up by systemd unless they contain a medium. This would mirror
698 the behaviour we already have for CD drives.
700 * networkd/udev: implement SR_IOV configuration in .link files:
701 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
703 * hostnamectl: show root image uuid
705 * Find a solution for SMACK capabilities stuff:
706 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
708 * "systemctl preset-all" should probably order the unit files it
709 operates on lexicographically before starting to work, in order to
710 ensure deterministic behaviour if two unit files conflict (like DMs
713 * synchronize console access with BSD locks:
714 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
716 * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
717 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
719 * figure out when we can use the coarse timers
721 * add "systemctl start -v foobar.service" that shows logs of a service
722 while the start command runs. This is non-trivial to do without
723 races though, since we should flush out all journal messages before
724 returning from the "systemctl stop".
726 * 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
728 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
730 * maybe allow timer units with an empty Units= setting, so that they
731 can be used for resuming the system but nothing else.
733 * what to do about udev db binary stability for apps? (raw access is not an option)
735 * systemctl: if some operation fails, show log output?
737 * systemctl edit: use equivalent of cat() to insert existing config as a comment, prepended with #.
738 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
740 * exponential backoff in timesyncd when we cannot reach a server
742 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
744 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
746 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
747 (throughout the codebase, not only PID1)
751 - service registration
752 - service/domain/types browsing
754 - DNS-SD service registration from socket units
755 - resolved should optionally register additional per-interface LLMNR
756 names, so that for the container case we can establish the same name
757 (maybe "host") for referencing the server, everywhere.
758 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
759 - hook up resolved with machined-based address resolution
761 * refcounting in sd-resolve is borked
763 * Add a new verb "systemctl top"
765 * add new gpt type for btrfs volumes
767 * support empty /etc boots nicely:
768 - nspawn/gpt-generator: introduce new gpt partition type for /usr
770 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
772 * a way for container managers to turn off getty starting via $container_headless= or so...
774 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
776 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
777 they run added to the initial transaction and thus confuse Type=idle.
779 * add bus api to query unit file's X fields.
781 * gpt-auto-generator:
782 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
783 - Make /home automount rather than mount?
785 * add generator that pulls in systemd-network from containers when
786 CAP_NET_ADMIN is set, more than the loopback device is defined, even
787 when it is otherwise off
789 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
791 * implement Distribute= in socket units to allow running multiple
792 service instances processing the listening socket, and open this up
795 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
796 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
797 should SIGSTOP all unit processes in a loop until all processes of
798 it are fully stopped. This can later be used for app management by
799 desktop UIs such as gnome-shell to freeze apps that are not visible
800 on screen, not unlike how job control works on the shell
803 - implement per-slice CPUFairScheduling=1 switch
804 - introduce high-level settings for RT budget, swappiness
805 - how to reset dynamically changed unit cgroup attributes sanely?
806 - when reloading configuration, apply new cgroup configuration
807 - when recursively showing the cgroup hierarchy, optionally also show
808 the hierarchies of child processes
811 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
813 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
815 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
817 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
819 * 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
821 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
823 * If we try to find a unit via a dangling symlink, generate a clean
824 error. Currently, we just ignore it and read the unit from the search
827 * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
829 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
831 * load .d/*.conf dropins for device units
835 - GetAllProperties() on a non-existing object does not result in a failure currently
836 - port to sd-resolve for connecting to TCP dbus servers
837 - 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
838 - see if we can drop more message validation on the sending side
839 - add API to clone sd_bus_message objects
840 - longer term: priority inheritance
842 - NameLost/NameAcquired obsolete
845 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
848 - allow multiple signal handlers per signal?
849 - document chaining of signal handler for SIGCHLD and child handlers
850 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
852 * investigate endianness issues of UUID vs. GUID
854 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
855 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
857 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
859 * add a pam module that on password changes updates any LUKS slot where the password matches
862 - add unit tests for config_parse_device_allow()
864 * seems that when we follow symlinks to units we prefer the symlink
865 destination path over /etc and /usr. We should not do that. Instead
866 /etc should always override /run+/usr and also any symlink
869 * when isolating, try to figure out a way how we implicitly can order
870 all units we stop before the isolating unit...
872 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
874 * Add ConditionDirectoryNotEmpty= handle non-absoute paths as a search path or add
875 ConditionConfigSearchPathNotEmpty= or different syntax? See the discussion starting at
876 https://github.com/systemd/systemd/pull/15109#issuecomment-607740136.
878 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
879 that the boot loader should be installed to the ESP. Define a way
880 how an installer can figure out whether a BLS compliant boot loader
883 * think about requeuing jobs when daemon-reload is issued? usecase:
884 the initrd issues a reload after fstab from the host is accessible
885 and we might want to requeue the mounts local-fs acquired through
888 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
890 * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
892 * shutdown logging: store to EFI var, and store to USB stick?
894 * merge unit_kill_common() and unit_kill_context()
897 - honor language efi variables for default language selection (if there are any?)
898 - honor timezone efi variables for default timezone selection (if there are any?)
899 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
901 - recognize the case when not booted on EFI
903 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
905 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
907 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
910 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
911 - logind: wakelock/opportunistic suspend support
912 - Add pretty name for seats in logind
913 - logind: allow showing logout dialog from system?
914 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
915 - if pam_systemd is invoked by su from a process that is outside of a
916 any session we should probably just become a NOP, since that's
917 usually not a real user session but just some system code that just
919 - logind: make the Suspend()/Hibernate() bus calls wait for the for
920 the job to be completed. before returning, so that clients can wait
921 for "systemctl suspend" to finish to know when the suspending is
923 - logind: when the power button is pressed short, just popup a
924 logout dialog. If it is pressed for 1s, do the usual
925 shutdown. Inspiration are Macs here.
926 - expose "Locked" property on logind sesison objects
927 - maybe allow configuration of the StopTimeout for session scopes
928 - rename session scope so that it includes the UID. THat way
929 the session scope can be arranged freely in slices and we don't have
930 make assumptions about their slice anymore.
931 - follow PropertiesChanged state more closely, to deal with quick logouts and
933 - (optionally?) spawn seat-manager@$SEAT.service whenever a seat shows up that as CanGraphical set
936 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
937 - journald: also get thread ID from client, plus thread name
938 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
939 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
940 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
941 - declare the local journal protocol stable in the wiki interface chart
942 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
943 - journald: when dropping msgs due to ratelimit make sure to write
944 "dropped %u messages" not only when we are about to print the next
945 message that works, but already after a short timeout
946 - check if we can make journalctl by default use --follow mode inside of less if called without args?
947 - maybe add API to send pairs of iovecs via sd_journal_send
948 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
949 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
950 and !FOOBAR for events without FOOBAR.
951 - journal: store timestamp of journal_file_set_offline() int he header,
952 so it is possible to display when the file was last synced.
953 - 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.
954 - journal: find a way to allow dropping history early, based on priority, other rules
955 - journal: When used on NFS, check payload hashes
956 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
957 - refuse taking lower-case variable names in sd_journal_send() and friends.
958 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
959 - journal: deal nicely with byte-by-byte copied files, especially regards header
960 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
961 - Replace utmp, wtmp, btmp, and lastlog completely with journal
962 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
963 - when a kernel driver logs in a tight loop, we should ratelimit that too.
964 - journald: optionally, log debug messages to /run but everything else to /var
965 - journald: when we drop syslog messages because the syslog socket is
966 full, make sure to write how many messages are lost as first thing
967 to syslog when it works again.
968 - journald: allow per-priority and per-service retention times when rotating/vacuuming
969 - journald: make use of uid-range.h to managed uid ranges to split
971 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
972 - improve journalctl performance by loading journal files
973 lazily. Encode just enough information in the file name, so that we
974 do not have to open it to know that it is not interesting for us, for
975 the most common operations.
976 - man: document that corrupted journal files is nothing to act on
977 - rework journald sigbus stuff to use mutex
978 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
979 services that run under their own user ids, and use User= (but only
980 in a world where userns is ubiquitous since otherwise we cannot
981 invoke those daemons on the host AND in a container anymore). Also,
982 if LimitNPROC= is used without User= we should warn and refuse
984 - journalctl --verify: don't show files that are currently being
985 written to as FAIL, but instead show that their are being written to.
986 - add journalctl -H that talks via ssh to a remote peer and passes through
988 - add a version of --merge which also merges /var/log/journal/remote
989 - journalctl: -m should access container journals directly by enumerating
990 them via machined, and also watch containers coming and going.
991 Benefit: nspawn --ephemeral would start working nicely with the journal.
992 - assign MESSAGE_ID to log messages about failed services
994 * add a test if all entries in the catalog are properly formatted.
995 (Adding dashes in a catalog entry currently results in the catalog entry
996 being silently skipped. journalctl --update-catalog must warn about this,
997 and we should also have a unit test to check that all our message are OK.)
1000 - document that deps in [Unit] sections ignore Alias= fields in
1001 [Install] units of other units, unless those units are disabled
1002 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
1003 - document that service reload may be implemented as service reexec
1004 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
1005 - document systemd-journal-flush.service properly
1006 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
1007 - man: document the very specific env the shutdown drop-in tools live in
1008 - man: add more examples to man pages
1009 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
1010 - document root=gpt-auto properly
1013 - add systemctl switch to dump transaction without executing it
1014 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
1015 - "systemctl disable" on a static unit prints no message and does
1016 nothing. "systemctl enable" does nothing, and gives a bad message
1017 about it. Should fix both to print nice actionable messages.
1018 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
1019 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
1020 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
1021 - systemctl: "Journal has been rotated since unit was started." message is misleading
1022 - systemctl status output should include list of triggering units and their status
1025 - "systemctl mask" should find all names by which a unit is accessible
1026 (i.e. by scanning for symlinks to it) and link them all to /dev/null
1029 - timer units should get the ability to trigger when:
1031 - Modulate timer frequency based on battery state
1033 * add libsystemd-password or so to query passwords during boot using the password agent logic
1035 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
1037 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
1039 * make repeated alt-ctrl-del presses printing a dump
1041 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
1043 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
1046 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
1047 with seccomp. That should provide us with a useful log buffer that
1048 systemd can log to during early boot, and disconnect container logs
1049 from the kernel's logs.
1050 - as soon as networkd has a bus interface, hook up --network-interface=,
1051 --network-bridge= with networkd, to trigger netdev creation should an
1052 interface be missing
1053 - a nice way to boot up without machine id set, so that it is set at boot
1054 automatically for supporting --ephemeral. Maybe hash the host machine id
1055 together with the machine name to generate the machine id for the container
1056 - fix logic always print a final newline on output.
1057 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
1058 - should optionally support receiving WATCHDOG=1 messages from its payload
1060 - optionally automatically add FORWARD rules to iptables whenever nspawn is
1061 running, remove them when shut down.
1064 - refuse mounting over a mount point
1065 - automatically discover .roothash files in dissect, similarly to nspawn
1068 - add an API so that libvirt-lxc can inform us about network interfaces being
1069 removed or added to an existing machine
1070 - "machinectl migrate" or similar to copy a container from or to a
1071 difference host, via ssh
1072 - introduce systemd-nspawn-ephemeral@.service, and hook it into
1073 "machinectl start" with a new --ephemeral switch
1074 - "machinectl status" should also show internal logs of the container in
1076 - "machinectl history"
1078 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
1079 shell in it, and marks it read-only after use
1082 - cryptsetup-generator: allow specification of passwords in crypttab itself
1083 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
1085 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
1086 https://bugs.freedesktop.org/show_bug.cgi?id=54712
1088 * add a dependency on standard-conf.xml and other included files to man pages
1090 * MountFlags=shared acts as MountFlags=slave right now.
1092 * properly handle loop back mounts via fstab, especially regards to fsck/passno
1094 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
1099 - add trigger --subsystem-match=usb/usb_device device
1100 - reimport udev db after MOVE events for devices without dev_t
1102 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
1104 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
1107 - save coredump in Windows/Mozilla minidump format
1108 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
1110 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
1112 * be able to specify a forced restart of service A where service B depends on, in case B
1113 needs to be auto-respawned?
1116 - apply "x" on "D" too (see patch from William Douglas)
1117 - instead of ignoring unknown fields, reject them.
1118 - creating new directories/subvolumes/fifos/device nodes
1119 should not follow symlinks. None of the other adjustment or creation
1120 calls follow symlinks.
1122 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
1124 * verify that the AF_UNIX sockets of a service in the fs still exist
1125 when we start a service in order to avoid confusion when a user
1126 assumes starting a service is enough to make it accessible
1128 * Make it possible to set the keymap independently from the font on
1129 the kernel cmdline. Right now setting one resets also the other.
1131 * and a dbus call to generate target from current state
1133 * write blog stories about:
1134 - hwdb: what belongs into it, lsusb
1135 - enabling dbus services
1136 - how to make changes to sysctl and sysfs attributes
1138 - how to pass throw-away units to systemd, or dynamically change properties of existing units
1139 - testing with Harald's awesome test kit
1141 - how to develop against journal browsing APIs
1142 - the journal HTTP iface
1143 - non-cgroup resource management
1144 - dynamic resource management with cgroups
1145 - refreshed, longer missions statement
1146 - calendar time events
1147 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
1148 - how to create your own target
1149 - instantiated apache, dovecot and so on
1150 - hooking a script into various stages of shutdown/rearly booot
1152 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
1154 * dot output for --test showing the 'initial transaction'
1157 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
1158 log both units as UNIT=, so that journalctl -u triggers on both.
1159 - generate better errors when people try to set transient properties
1160 that are not supported...
1161 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
1162 - maybe introduce WantsMountsFor=? Usecase:
1163 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
1164 - recreate systemd's D-Bus private socket file on SIGUSR2
1165 - move PAM code into its own binary
1166 - when we automatically restart a service, ensure we restart its rdeps, too.
1167 - hide PAM options in fragment parser when compile time disabled
1168 - Support --test based on current system state
1169 - 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().
1170 - after deserializing sockets in socket.c we should reapply sockopts and things
1171 - drop PID 1 reloading, only do reexecing (difficult: Reload()
1172 currently is properly synchronous, Reexec() is weird, because we
1173 cannot delay the response properly until we are back, so instead of
1174 being properly synchronous we just keep open the fd and close it
1175 when done. That means clients do not get a successful method reply,
1176 but much rather a disconnect on success.
1177 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
1178 - when a bus name of a service disappears from the bus make sure to queue further activation requests
1181 - allow port=0 in .socket units
1182 - maybe introduce ExecRestartPre=
1183 - add ReloadSignal= for configuring a reload signal to use
1184 - implement Register= switch in .socket units to enable registration
1185 in Avahi, RPC and other socket registration services.
1186 - allow Type=simple with PIDFile=
1187 https://bugzilla.redhat.com/show_bug.cgi?id=723942
1188 - allow writing multiple conditions in unit files on one line
1189 - introduce Type=pid-file
1190 - introduce mix of BindTo and Requisite
1191 - add a concept of RemainAfterExit= to scope units
1192 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
1193 - add verification of [Install] section to systemd-analyze verify
1196 - Make sure ID_PATH is always exported and complete for
1197 network devices where possible, so we can safely rely
1201 - add support for more attribute types
1202 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
1205 - add more keys to [Route] and [Address] sections
1206 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
1207 - add reduced [Link] support to .network files
1208 - properly handle routerless dhcp leases
1209 - work with non-Ethernet devices
1210 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
1211 - the DHCP lease data (such as NTP/DNS) is still made available when
1212 a carrier is lost on a link. It should be removed instantly.
1213 - expose in the API the following bits:
1214 - option 15, domain name
1215 - option 12, hostname and/or option 81, fqdn
1216 - option 123, 144, geolocation
1217 - option 252, configure http proxy (PAC/wpad)
1218 - provide a way to define a per-network interface default metric value
1219 for all routes to it. possibly a second default for DHCP routes.
1220 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
1221 support Name=foo*|bar*|baz ?
1222 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
1223 - whenever uplink info changes, make DHCP server send out FORCERENEW
1226 - figure out how much we can increase Maximum Message Size
1229 - add functions to set previously stored IPv6 addresses on startup and get
1230 them at shutdown; store them in client->ia_na
1231 - write more test cases
1232 - implement reconfigure support, see 5.3., 15.11. and 22.20.
1233 - implement support for temporary adressess (IA_TA)
1234 - implement dhcpv6 authentication
1235 - investigate the usefulness of Confirm messages; i.e. are there any
1236 situations where the link changes without any loss in carrier detection
1238 - some servers don't do rapid commit without a filled in IA_NA, verify
1245 - natively watch for dbus-*.service symlinks (PENDING)
1246 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
1248 * make cryptsetup lower --iter-time
1250 * kernel: add device_type = "fb", "fbcon" to class "graphics"
1252 * /usr/bin/service should actually show the new command line
1254 * fedora: suggest auto-restart on failure, but not on success and not on coredump. also, ask people to think about changing the start limit logic. Also point people to RestartPreventExitStatus=, SuccessExitStatus=
1256 * neither pkexec nor sudo initialize environ[] from the PAM environment?
1258 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
1260 * register catalog database signature as file magic
1262 * zsh shell completion:
1263 - <command> <verb> -<TAB> should complete options, but currently does not
1264 - systemctl add-wants,add-requires
1266 * systemctl status should know about 'systemd-analyze calendar ... --iterations='
1267 * If timer has just OnInactiveSec=..., it should fire after a specified time
1268 after being started.
1272 * look for close() vs. close_nointr() vs. close_nointr_nofail()
1274 * check for strerror(r) instead of strerror(-r)
1278 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
1280 * use secure_getenv() instead of getenv() where appropriate
1282 * link up selected blog stories from man pages and unit files Documentation= fields
1283 String is not UTF-8 clean, ignoring assignment
