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.
9 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
11 * wiki: update journal format documentation for lz4 additions
15 * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
17 * rework mount.c and swap.c to follow proper state enumeration/deserialization
18 semantics, like we do for device.c now
22 * revisit SystemdOptions EFI variable. Find a better, systematic name and use
23 it for the env var, the bootctl verb and the EFI variable itself, clear up
26 * Figure out a better name for the global per-unit-type drop-in dirs, it's
27 confusing when it comes to -.mount.d/ (is it a drop-in-dir for all mount
28 units, or one for the root mount?). Also, OOM handling in
29 service_unit_name_is_valid() is borked.
33 * localed: if UTC is selected but timezone file for it doesn't exist, delete
34 /etc/localtime instead of creating a symlink
36 * socket units: allow creating a udev monitor socket with ListenDevices= or so,
37 with matches, then actviate app thorugh that passing socket oveer
39 * coredump: maybe when coredumping read a new xattr from /proc/$PID/exe that
40 may be used to mark a whole binary as non-coredumpable. Would fix:
41 https://bugs.freedesktop.org/show_bug.cgi?id=69447
43 * beef up hibernation to optionally do swapon/swapoff immediately before/after
46 * beef up s2h to implement a battery watch loop: instead of entering
47 hibernation unconditionally after coming back from resume make a decision
48 based on the battery load level: if battery level is above a specific
49 threshold, go to suspend again, only hibernate if below it. This means we'd
50 stick to suspend usually, but fall back to hibernation only when battery runs
51 empty (well, subject to our sampling interval). Related to this, check if we
52 can make ACPI _BTP (i.e. /sys/class/power_supply/*/alarm) work for us too,
53 i.e. see if it can wake up machines from suspend, so that we could resume
54 automatically when the system is low on power and move automatically to
55 hibernation mode. (see
56 https://uefi.org/sites/default/files/resources/ACPI%206_2_A_Sept29.pdf
58 https://docs.microsoft.com/en-us/windows-hardware/design/device-experiences/modern-standby-wake-sources
61 * add an explicit "vertical" mode to format-table, so that "systemctl
62 status"-like outputs (i.e. with a series of field names left and values
63 right) become genuine first class citizens, and we gain automatic, sane JSON
66 * dissector: invoke fsck on the file systems we encounter, after all ext4 is
67 still pretty popular (and we mount the ESP too with it after all, which is
70 * systemd-firstboot: teach it dissector magic, so that you can point it to some
71 disk image and it will just set everything in it all behind the scenes.
73 * systemd-firstboot: add --force mode that replaces existing configuration.
75 * We should probably replace /var/log/README, /etc/rc.d/README with symlinks
76 that are linked to these places instead of copied. After all they are
79 * maybe add kernel cmdline params: 1) to force first-boot mode + 2) to force
82 * nspawn: on cgroupsv1 issue cgroup empty handler process based on host events,
83 so that we make cgroup agent logic safe
85 * nspawn/machined: add API to invoke binary in container, then use that as
86 fallback in "machinectl shell"
88 * logind: rework pam_logind to also do a bus call in case of invocation from
89 user@.service, which returns the XDG_RUNTIME_DIR value, and make this
90 behaviour selectable via pam module option.
92 * introduce a new per-process uuid, similar to the boot id, the machine id, the
93 invocation id, that is derived from process creds, specifically a hashed
94 combination of AT_RANDOM + getpid() + the starttime from
95 /proc/self/status. Then add these ids implicitly when logging. Deriving this
96 uuid from these three things has the benefit that it can be derived easily
97 from /proc/$PID/ in a stable, and unique way that changes on both fork() and
100 * let's not GC a unit while its ratelimits are still pending
102 * when killing due to service watchdog timeout maybe detect whether target
103 process is under ptracing and then log loudly and continue instead.
105 * introduce a new group to own TPM devices
107 * make rfkill uaccess controllable by default, i.e. steal rule from
108 gnome-bluetooth and friends
110 * tweak journald context caching. In addition to caching per-process attributes
111 keyed by PID, cache per-cgroup attributes (i.e. the various xattrs we read)
112 keyed by cgroup path, and guarded by ctime changes. This should provide us
113 with a nice speed-up on services that have many processes running in the same
116 * make MAINPID= message reception checks even stricter: if service uses User=,
117 then check sending UID and ignore message if it doesn't match the user or
120 * maybe trigger a uevent "change" on a device if "systemctl reload xyz.device"
123 * when importing an fs tree with machined, optionally apply userns-rec-chown
125 * when importing an fs tree with machined, complain if image is not an OS
127 * Maybe introduce a helper safe_exec() or so, which is to execve() which
128 safe_fork() is to fork(). And then make revert the RLIMIT_NOFILE soft limit
129 to 1K implicitly, unless explicitly opted-out.
131 * rework seccomp/nnp logic that even if User= is used in combination with
132 a seccomp option we don't have to set NNP. For that, change uid first whil
133 keeping CAP_SYS_ADMIN, then apply seccomp, the drop cap.
135 * add a concept for automatically loading per-unit secrets off disk and
136 inserting them into the kernel keyring. Maybe SecretsDirectory= similar to
137 ConfigurationDirectory=.
139 * when no locale is configured, default to UEFI's PlatformLang variable
141 * bootctl,sd-boot: actually honour the "architecture" key
143 * add a new syscall group "@esoteric" for more esoteric stuff such as bpf() and
144 usefaultd() and make systemd-analyze check for it.
146 * paranoia: whenever we process passwords, call mlock() on the memory
147 first. i.e. look for all places we use free_and_erasep() and
148 augment them with mlock(). Also use MADV_DONTDUMP.
150 * Move RestrictAddressFamily= to the new cgroup create socket
152 * support the bind/connect/sendmsg cgroup stuff for sandboxing, and possibly
155 * maybe implicitly attach monotonic+realtime timestamps to outgoing messages in
156 log.c and sd-journal-send
158 * optionally: turn on cgroup delegation for per-session scope units
160 * introduce per-unit (i.e. per-slice, per-service) journal log size limits.
162 * optionally, if a per-partition GPT flag is set for the root/home/… partitions
163 format the partition on next boot and unset the flag, in order to implement
164 factory reset. also, add a second flag that simply indicates whether such a
165 scheme is supported. then, add a tool (or maybe beef up systemd-dissect) to
166 show state of these flags, and optionally trigger such a factory reset on
167 next boot by setting the flag.
169 * sd-boot: automatically load EFI modules from some drop-in dir, so that people
170 can add in file system drivers and such
172 * sd-boot: optionally, show boot menu when previous default boot item has
173 non-zero "tries done" count
175 * maybe set a special xattr on cgroups that have delegate=yes set, to make it
176 easy to mark cut points, then use this information in "systemd-cgls" to show
177 them (e.g. color delegated subtrees in a different color)
179 * introduce an option (or replacement) for "systemctl show" that outputs all
180 properties as JSON, similar to busctl's new JSON output. In contrast to that
181 it should skip the variant type string though.
183 * augment CODE_FILE=, CODE_LINE= with something like CODE_BASE= or so which
184 contains some identifier for the project, which allows us to include
185 clickable links to source files generating these log messages. The identifier
186 could be some abberviated URL prefix or so (taking inspiration from Go
187 imports). For example, for systemd we could use
188 CODE_BASE=github.com/systemd/systemd/blob/98b0b1123cc or so which is
189 sufficient to build a link by prefixing "http://" and suffixing the
192 * Augment MESSAGE_ID with MESSAGE_BASE, in a similar fashion so that we can
193 make clickable links from log messages carrying a MESSAGE_ID, that lead to
194 some explanatory text online.
196 * maybe extend .path units to expose fanotify() per-mount change events
198 * Add a "systemctl list-units --by-slice" mode or so, which rearranges the
199 output of "systemctl list-units" slightly by showing the tree structure of
200 the slices, and the units attached to them.
202 * the a-posteriori stopping of units bound to units that disappeared logic
203 should be reworked: there should be a queue of units, and we should only
204 enqeue stop jobs from a defer event that processes queue instead of
205 right-away when we find a unit that is bound to one that doesn't exist
206 anymore. (similar to how the stop-unneeded queue has been reworked the same
209 * nspawn: make nspawn suitable for shell pipelines: instead of triggering a
210 hangup when input is finished, send ^D, which synthesizes an EOF. Then wait
211 for hangup or ^D before passing on the EOF.
213 * When reloading configuration PID 1 should reset all its properties to the
214 original defaults before calling parse_config()
216 * nspawn: greater control over selinux label?
218 * hibernate/s2h: make this robust and safe to enable in Fedora by default.
221 1. add resume_offset support to the resume code (i.e. support swap files
223 2. check if swap is on weird storage and refuse if so
224 3. add autodetection of hibernation images
226 * cgroups: use inotify to get notified when somebody else modifies cgroups
227 owned by us, then log a friendly warning.
229 * beef up log.c with support for stripping ANSI sequences from strings, so that
230 it is OK to include them in log strings. This would be particularly useful so
231 that our log messages could contain clickable links for example for unit
232 files and suchlike we operate on.
234 * add support for "portablectl attach http://foobar.com/waaa.raw (i.e. importd integration)
236 * add attach --enable and attach --now (for attach+enable+start)
238 * sync dynamic uids/gids between host+portable srvice (i.e. if DynamicUser=1 is set for a service, make sure that the
239 selected user is resolvable in the service even if it ships its own /etc/passwd)
241 * Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the
242 other doesn't. What a disaster. Probably to exclude it. Also
243 DECIMAL_STR_WIDTH should probably add an extra "-" into account for negative
246 * Check that users of inotify's IN_DELETE_SELF flag are using it properly, as
247 usually IN_ATTRIB is the right way to watch deleted files, as the former only
248 fires when a file is actually removed from disk, i.e. the link count drops to
249 zero and is not open anymore, while the latter happens when a file is
250 unlinked from any dir.
252 * port systemctl, busctl, … over to format-table.[ch]'s table formatters
254 * pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up
256 * add --vacuum-xyz options to coredumpctl, matching those journalctl already has.
258 * introduce Ephemeral= unit file switch, that creates an ephemeral copy of all
259 files and directories that are left writable for a unit, and which are
260 removed after the unit goes down again. A bit like --ephemeral for
261 systemd-nspawn but for system services. If used together with RootImage= this
262 should reflink the image file itself.
264 Related: add Ephemeral=<path1> <path2> … which would allow marking
265 specific paths only like this.
267 * add CopyFile= or so as unit file setting that may be used to copy files or
268 directory trees from the host to the services RootImage= and RootDirectory=
269 environment. Which we can use for /etc/machine-id and in particular
270 /etc/resolv.conf. Should be smart and do something useful on read-only
271 images, for example fallback to read-only bind mounting the file instead.
273 * show invocation ID in systemd-run output
275 * bypass SIGTERM state in unit files if KillSignal is SIGKILL
277 * add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1
278 and so on, which would mean we could report errors and such.
280 * teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4
283 * introduce DefaultSlice= or so in system.conf that allows changing where we
284 place our units by default, i.e. change system.slice to something
285 else. Similar, ManagerSlice= should exist so that PID1's own scope unit could
286 be moved somewhere else too. Finally machined and logind should get similar
287 options so that it is possible to move user session scopes and machines to a
288 different slice too by default. Usecase: people who want to put resources on
289 the entire system, with the exception of one specific service. See:
290 https://lists.freedesktop.org/archives/systemd-devel/2018-February/040369.html
292 * maybe rework get_user_creds() to query the user database if $SHELL is used
293 for root, but only then.
295 * be stricter with fds we receive for the fdstore: close them asynchronously
297 * calenderspec: add support for week numbers and day numbers within a
298 year. This would allow us to define "bi-weekly" triggers safely.
300 * sd-bus: add vtable flag, that may be used to request client creds implicitly
301 and asynchronously before dispatching the operation
303 * make use of ethtool veth peer info in machined, for automatically finding out
304 host-side interface pointing to the container.
306 * add some special mode to LogsDirectory=/StateDirectory=… that allows
307 declaring these directories without necessarily pulling in deps for them, or
308 creating them when starting up. That way, we could declare that
309 systemd-journald writes to /var/log/journal, which could be useful when we
310 doing disk usage calculations and so on.
312 * taint systemd if there are fewer than 65536 users assigned (userns) to the system.
314 * deprecate RootDirectoryStartOnly= in favour of a new ExecStart= prefix char
316 * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
317 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
318 as the unit is running or has a job queued.
320 * support projid-based quota in machinectl for containers
322 * maybe use SOURCE_DATE_EPOCH (i.e. the env var the reproducible builds folks
323 introduced) as the RTC epoch, instead of the mtime of NEWS.
325 * add a way to lock down cgroup migration: a boolean, which when set for a unit
326 makes sure the processes in it can never migrate out of it
328 * blog about fd store and restartable services
330 * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
332 * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
333 magic meaning and is no longer upgraded to something else if set explicitly.
335 * in the long run: permit a system with /etc/machine-id linked to /dev/null, to
336 make it lose its identity, i.e. be anonymous. For this we'd have to patch
337 through the whole tree to make all code deal with the case where no machine
340 * optionally, collect cgroup resource data, and store it in per-unit RRD files,
341 suitable for processing with rrdtool. Add bus API to access this data, and
342 possibly implement a CPULoad property based on it.
344 * beef up pam_systemd to take unit file settings such as cgroups properties as
347 * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
348 the quota of a the user indicated in User= via unit file settings, like the
349 other resource management concepts. Would mix nicely with DynamicUser=1. Or
350 alternatively, do this with projids, so that we can also cover services
351 running as root. Quota should probably cover all the special dirs such as
352 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
353 is set, plus the whole disk space any image configured with RootImage=.
355 * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
356 disks to see if the UID is already in use.
358 * add "systemctl wait" or so, which does what "systemd-run --wait" does, but
359 for all units. It should be both a way to pin units into memory as well as a
360 wait to retrieve their exit data.
362 * expose IO accounting data on the bus, show it in systemd-run --wait and log
363 about it in the resource log message
365 * show whether a service has out-of-date configuration in "systemctl status" by
366 using mtime data of ConfigurationDirectory=.
368 * replace all remaining uses of fgets() + LINE_MAX by read_line()
370 * Add AddUser= setting to unit files, similar to DynamicUser=1 which however
371 creates a static, persistent user rather than a dynamic, transient user. We
372 can leverage code from sysusers.d for this.
374 * add some optional flag to ReadWritePaths= and friends, that has the effect
375 that we create the dir in question when the service is started. Example:
377 ReadWritePaths=:/var/lib/foobar
379 * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
380 the sd-journal logging socket, and, if the timeout is set to 0, sets
381 O_NONBLOCK on it. That way people can control if and when to block for
384 * hostnamed: populate form factor data from a new hwdb database, so that old
385 yogas can be recognized as "convertible" too, even if they predate the DMI
386 "convertible" form factor
388 * Maybe add a small tool invoked early at boot, that adds in or resizes
389 partitions automatically, to be used when the media used is actually larger
390 than the image written onto it is.
392 * Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
393 after all. Be strict however, only support the equivalent of nspawn's
394 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
397 * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
398 the service cgroup, which is supposed to monitor the service, and when it
399 exits the service is considered failed by its monitor.
401 * track the per-service PAM process properly (i.e. as an additional control
402 process), so that it may be queried on the bus and everything.
404 * add a new "debug" job mode, that is propagated to unit_start() and for
405 services results in two things: we raise SIGSTOP right before invoking
406 execve() and turn off watchdog support. Then, use that to implement
407 "systemd-gdb" for attaching to the start-up of any system service in its
410 * maybe introduce gpt auto discovery for /var/tmp?
412 * maybe add gpt-partition-based user management: each user gets his own
413 LUKS-encrypted GPT partition with a new GPT type. A small nss module
414 enumerates users via udev partition enumeration. UIDs are assigned in a fixed
415 way: the partition index is added as offset to some fixed base uid. User name
416 is stored in GPT partition name. A PAM module authenticates the user via the
417 LUKS partition password. Benefits: strong per-user security, compatibility
418 with stateless/read-only/verity-enabled root. (other idea: do this based on
419 loopback files in /home, without GPT involvement)
421 * gpt-auto logic: introduce support for discovering /var matching an image. For
422 that, use a partition type UUID that is hashed from the OS name (as encoded
423 in /etc/os-release), the architecture, and 4 new bits from the gpt flags
424 field of the root partition. This way can easily support multiple OS
425 installations on the same GPT partition table, without problems with
426 unmatched /var partitions.
428 * gpt-auto logic: related to the above, maybe support a "secondary" root
429 partition, that is mounted to / and is writable, and where the actual root's
430 /usr is mounted into.
432 * 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
434 * drop nss-myhostname in favour of nss-resolve?
436 * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
437 then use that for the setting used in user@.service. It should be understood
438 relative to the configured default value.
440 * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
442 * enable LockMLOCK to take a percentage value relative to physical memory
444 * Permit masking specific netlink APIs with RestrictAddressFamily=
446 * nspawn: support that /proc, /sys/, /dev are pre-mounted
448 * define gpt header bits to select volatility mode
450 * ProtectKernelLogs= (drops CAP_SYSLOG, add seccomp for syslog() syscall, and DeviceAllow to /dev/kmsg) in service files
452 * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
454 * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
456 * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
458 * ProtectKeyRing= to take keyring calls away
460 * RemoveKeyRing= to remove all keyring entries of the specified user
462 * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
463 on PID 1 with the relevant signals, and makes relevant files in /sys and
464 /proc (such as the sysrq stuff) unavailable
466 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
468 * journalctl: make sure -f ends when the container indicated by -M terminates
470 * mount: automatically search for "main" partition of an image has multiple
473 * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
474 find a way to map the User=/Group= of the service to the right name. This way
475 a user/group for a service only has to exist on the host for the right
478 * add bus API for creating unit files in /etc, reusing the code for transient units
480 * add bus API to remove unit files from /etc
482 * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
484 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
485 kernel doesn't support linkat() that replaces existing files, currently)
487 * transient units: don't bother with actually setting unit properties, we
488 reload the unit file anyway
490 * journald: sigbus API via a signal-handler safe function that people may call
491 from the SIGBUS handler
493 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
495 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
496 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
498 * cache sd_event_now() result from before the first iteration...
500 * PID1: find a way how we can reload unit file configuration for
501 specific units only, without reloading the whole of systemd
503 * add an explicit parser for LimitRTPRIO= that verifies
504 the specified range and generates sane error messages for incorrect
507 * when we detect that there are waiting jobs but no running jobs, do something
509 * push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
511 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
513 * there's probably something wrong with having user mounts below /sys,
514 as we have for debugfs. for example, src/core/mount.c handles mounts
515 prefixed with /sys generally special.
516 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
518 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
520 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
522 * add a job mode that will fail if a transaction would mean stopping
523 running units. Use this in timedated to manage the NTP service
525 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
527 * The udev blkid built-in should expose a property that reflects
528 whether media was sensed in USB CF/SD card readers. This should then
529 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
530 picked up by systemd unless they contain a medium. This would mirror
531 the behaviour we already have for CD drives.
533 * networkd/udev: implement SR_IOV configuration in .link files:
534 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
536 * hostnamectl: show root image uuid
538 * Find a solution for SMACK capabilities stuff:
539 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
541 * "systemctl preset-all" should probably order the unit files it
542 operates on lexicographically before starting to work, in order to
543 ensure deterministic behaviour if two unit files conflict (like DMs
546 * synchronize console access with BSD locks:
547 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
549 * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
550 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
552 * in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
554 * figure out when we can use the coarse timers
556 * add "systemctl start -v foobar.service" that shows logs of a service
557 while the start command runs. This is non-trivial to do without
558 races though, since we should flush out all journal messages before
559 returning from the "systemctl stop".
561 * 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
563 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
565 * maybe allow timer units with an empty Units= setting, so that they
566 can be used for resuming the system but nothing else.
568 * what to do about udev db binary stability for apps? (raw access is not an option)
570 * man: maybe use the word "inspect" rather than "introspect"?
572 * systemctl: if some operation fails, show log output?
574 * systemctl edit: use equivalent of cat() to insert existing config as a comment, prepended with #.
575 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
577 * exponential backoff in timesyncd when we cannot reach a server
579 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
581 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
583 * systemd.show_status= should probably have a mode where only failed
586 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
587 (throughout the codebase, not only PID1)
591 - service registration
592 - service/domain/types browsing
594 - DNS-SD service registration from socket units
595 - resolved should optionally register additional per-interface LLMNR
596 names, so that for the container case we can establish the same name
597 (maybe "host") for referencing the server, everywhere.
598 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
599 - hook up resolved with machined-based address resolution
601 * refcounting in sd-resolve is borked
603 * Add a new verb "systemctl top"
605 * add new gpt type for btrfs volumes
607 * support empty /etc boots nicely:
608 - nspawn/gpt-generator: introduce new gpt partition type for /usr
610 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
612 * a way for container managers to turn off getty starting via $container_headless= or so...
614 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
616 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
617 they run added to the initial transaction and thus confuse Type=idle.
619 * add bus api to query unit file's X fields.
621 * gpt-auto-generator:
622 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
623 - Make /home automount rather than mount?
625 * add generator that pulls in systemd-network from containers when
626 CAP_NET_ADMIN is set, more than the loopback device is defined, even
627 when it is otherwise off
629 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
631 * implement Distribute= in socket units to allow running multiple
632 service instances processing the listening socket, and open this up
635 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
636 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
637 should SIGSTOP all unit processes in a loop until all processes of
638 it are fully stopped. This can later be used for app management by
639 desktop UIs such as gnome-shell to freeze apps that are not visible
640 on screen, not unlike how job control works on the shell
643 - implement per-slice CPUFairScheduling=1 switch
644 - introduce high-level settings for RT budget, swappiness
645 - how to reset dynamically changed unit cgroup attributes sanely?
646 - when reloading configuration, apply new cgroup configuration
647 - when recursively showing the cgroup hierarchy, optionally also show
648 the hierarchies of child processes
651 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
653 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
655 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
657 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
659 * 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
661 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
663 * If we try to find a unit via a dangling symlink, generate a clean
664 error. Currently, we just ignore it and read the unit from the search
667 * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
669 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
671 * load .d/*.conf dropins for device units
675 - GetAllProperties() on a non-existing object does not result in a failure currently
676 - port to sd-resolve for connecting to TCP dbus servers
677 - 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
678 - see if we can drop more message validation on the sending side
679 - add API to clone sd_bus_message objects
680 - longer term: priority inheritance
682 - NameLost/NameAcquired obsolete
685 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
688 - allow multiple signal handlers per signal?
689 - document chaining of signal handler for SIGCHLD and child handlers
690 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
691 - generate a failure of a default event loop is executed out-of-thread
693 * investigate endianness issues of UUID vs. GUID
695 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
696 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
698 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
700 * add a pam module that on password changes updates any LUKS slot where the password matches
703 - add unit tests for config_parse_device_allow()
705 * seems that when we follow symlinks to units we prefer the symlink
706 destination path over /etc and /usr. We should not do that. Instead
707 /etc should always override /run+/usr and also any symlink
710 * when isolating, try to figure out a way how we implicitly can order
711 all units we stop before the isolating unit...
713 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
715 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
716 that the boot loader should be installed to the ESP. Define a way
717 how an installer can figure out whether a BLS compliant boot loader
720 * think about requeuing jobs when daemon-reload is issued? usecase:
721 the initrd issues a reload after fstab from the host is accessible
722 and we might want to requeue the mounts local-fs acquired through
725 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
727 * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
729 * shutdown logging: store to EFI var, and store to USB stick?
731 * merge unit_kill_common() and unit_kill_context()
734 - honor language efi variables for default language selection (if there are any?)
735 - honor timezone efi variables for default timezone selection (if there are any?)
736 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
738 - recognize the case when not booted on EFI
740 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
742 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
744 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
747 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
748 - logind: wakelock/opportunistic suspend support
749 - Add pretty name for seats in logind
750 - logind: allow showing logout dialog from system?
751 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
752 - if pam_systemd is invoked by su from a process that is outside of a
753 any session we should probably just become a NOP, since that's
754 usually not a real user session but just some system code that just
756 - logind: make the Suspend()/Hibernate() bus calls wait for the for
757 the job to be completed. before returning, so that clients can wait
758 for "systemctl suspend" to finish to know when the suspending is
760 - logind: when the power button is pressed short, just popup a
761 logout dialog. If it is pressed for 1s, do the usual
762 shutdown. Inspiration are Macs here.
763 - expose "Locked" property on logind sesison objects
764 - maybe allow configuration of the StopTimeout for session scopes
765 - rename session scope so that it includes the UID. THat way
766 the session scope can be arranged freely in slices and we don't have
767 make assumptions about their slice anymore.
768 - follow PropertiesChanged state more closely, to deal with quick logouts and
772 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
773 - journald: also get thread ID from client, plus thread name
774 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
775 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
776 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
777 - declare the local journal protocol stable in the wiki interface chart
778 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
779 - journald: when dropping msgs due to ratelimit make sure to write
780 "dropped %u messages" not only when we are about to print the next
781 message that works, but already after a short timeout
782 - check if we can make journalctl by default use --follow mode inside of less if called without args?
783 - maybe add API to send pairs of iovecs via sd_journal_send
784 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
785 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
786 and !FOOBAR for events without FOOBAR.
787 - journal: store timestamp of journal_file_set_offline() int he header,
788 so it is possible to display when the file was last synced.
789 - 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.
790 - journal: find a way to allow dropping history early, based on priority, other rules
791 - journal: When used on NFS, check payload hashes
792 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
793 - refuse taking lower-case variable names in sd_journal_send() and friends.
794 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
795 - journal: deal nicely with byte-by-byte copied files, especially regards header
796 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
797 - Replace utmp, wtmp, btmp, and lastlog completely with journal
798 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
799 - when a kernel driver logs in a tight loop, we should ratelimit that too.
800 - journald: optionally, log debug messages to /run but everything else to /var
801 - journald: when we drop syslog messages because the syslog socket is
802 full, make sure to write how many messages are lost as first thing
803 to syslog when it works again.
804 - change systemd-journal-flush into a service that stays around during
805 boot, and causes the journal to be moved back to /run on shutdown,
806 so that we do not keep /var busy. This needs to happen synchronously,
807 hence doing this via signals is not going to work.
808 - optionally support running journald from the command line for testing purposes in external projects
809 - journald: allow per-priority and per-service retention times when rotating/vacuuming
810 - journald: make use of uid-range.h to managed uid ranges to split
812 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
813 - improve journalctl performance by loading journal files
814 lazily. Encode just enough information in the file name, so that we
815 do not have to open it to know that it is not interesting for us, for
816 the most common operations.
817 - man: document that corrupted journal files is nothing to act on
818 - rework journald sigbus stuff to use mutex
819 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
820 services that run under their own user ids, and use User= (but only
821 in a world where userns is ubiquitous since otherwise we cannot
822 invoke those daemons on the host AND in a container anymore). Also,
823 if LimitNPROC= is used without User= we should warn and refuse
825 - journalctl --verify: don't show files that are currently being
826 written to as FAIL, but instead show that their are being written to.
827 - add journalctl -H that talks via ssh to a remote peer and passes through
829 - add a version of --merge which also merges /var/log/journal/remote
830 - journalctl: -m should access container journals directly by enumerating
831 them via machined, and also watch containers coming and going.
832 Benefit: nspawn --ephemeral would start working nicely with the journal.
833 - assign MESSAGE_ID to log messages about failed services
835 * add a test if all entries in the catalog are properly formatted.
836 (Adding dashes in a catalog entry currently results in the catalog entry
837 being silently skipped. journalctl --update-catalog must warn about this,
838 and we should also have a unit test to check that all our message are OK.)
841 - document that deps in [Unit] sections ignore Alias= fields in
842 [Install] units of other units, unless those units are disabled
843 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
844 - document that service reload may be implemented as service reexec
845 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
846 - document systemd-journal-flush.service properly
847 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
848 - man: document the very specific env the shutdown drop-in tools live in
849 - man: add more examples to man pages
850 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
851 - document root=gpt-auto properly
854 - add systemctl switch to dump transaction without executing it
855 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
856 - "systemctl disable" on a static unit prints no message and does
857 nothing. "systemctl enable" does nothing, and gives a bad message
858 about it. Should fix both to print nice actionable messages.
859 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
860 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
861 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
862 - systemctl: "Journal has been rotated since unit was started." message is misleading
863 - systemctl status output should include list of triggering units and their status
866 - "systemctl mask" should find all names by which a unit is accessible
867 (i.e. by scanning for symlinks to it) and link them all to /dev/null
870 - timer units should get the ability to trigger when:
872 - Modulate timer frequency based on battery state
874 * add libsystemd-password or so to query passwords during boot using the password agent logic
876 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
878 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
880 * make repeated alt-ctrl-del presses printing a dump
882 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
884 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
887 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
888 with seccomp. That should provide us with a useful log buffer that
889 systemd can log to during early boot, and disconnect container logs
890 from the kernel's logs.
891 - as soon as networkd has a bus interface, hook up --network-interface=,
892 --network-bridge= with networkd, to trigger netdev creation should an
894 - a nice way to boot up without machine id set, so that it is set at boot
895 automatically for supporting --ephemeral. Maybe hash the host machine id
896 together with the machine name to generate the machine id for the container
897 - fix logic always print a final newline on output.
898 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
899 - should optionally support receiving WATCHDOG=1 messages from its payload
901 - optionally automatically add FORWARD rules to iptables whenever nspawn is
902 running, remove them when shut down.
905 - refuse mounting over a mount point
906 - automatically discover .roothash files in dissect, similarly to nspawn
909 - add an API so that libvirt-lxc can inform us about network interfaces being
910 removed or added to an existing machine
911 - "machinectl migrate" or similar to copy a container from or to a
912 difference host, via ssh
913 - introduce systemd-nspawn-ephemeral@.service, and hook it into
914 "machinectl start" with a new --ephemeral switch
915 - "machinectl status" should also show internal logs of the container in
917 - "machinectl history"
919 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
920 shell in it, and marks it read-only after use
923 - cryptsetup-generator: allow specification of passwords in crypttab itself
924 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
926 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
927 https://bugs.freedesktop.org/show_bug.cgi?id=54712
929 * add a dependency on standard-conf.xml and other included files to man pages
931 * MountFlags=shared acts as MountFlags=slave right now.
933 * properly handle loop back mounts via fstab, especially regards to fsck/passno
935 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
940 - add trigger --subsystem-match=usb/usb_device device
941 - reimport udev db after MOVE events for devices without dev_t
943 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
945 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
948 - save coredump in Windows/Mozilla minidump format
949 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
951 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
953 * be able to specify a forced restart of service A where service B depends on, in case B
954 needs to be auto-respawned?
957 - apply "x" on "D" too (see patch from William Douglas)
958 - instead of ignoring unknown fields, reject them.
959 - creating new directories/subvolumes/fifos/device nodes
960 should not follow symlinks. None of the other adjustment or creation
961 calls follow symlinks.
963 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
965 * verify that the AF_UNIX sockets of a service in the fs still exist
966 when we start a service in order to avoid confusion when a user
967 assumes starting a service is enough to make it accessible
969 * Make it possible to set the keymap independently from the font on
970 the kernel cmdline. Right now setting one resets also the other.
972 * and a dbus call to generate target from current state
974 * write blog stories about:
975 - hwdb: what belongs into it, lsusb
976 - enabling dbus services
977 - how to make changes to sysctl and sysfs attributes
979 - how to pass throw-away units to systemd, or dynamically change properties of existing units
980 - testing with Harald's awesome test kit
982 - how to develop against journal browsing APIs
983 - the journal HTTP iface
984 - non-cgroup resource management
985 - dynamic resource management with cgroups
986 - refreshed, longer missions statement
987 - calendar time events
988 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
989 - how to create your own target
990 - instantiated apache, dovecot and so on
991 - hooking a script into various stages of shutdown/rearly booot
993 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
995 * dot output for --test showing the 'initial transaction'
998 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
999 log both units as UNIT=, so that journalctl -u triggers on both.
1000 - generate better errors when people try to set transient properties
1001 that are not supported...
1002 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
1003 - maybe introduce WantsMountsFor=? Usecase:
1004 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
1005 - recreate systemd's D-Bus private socket file on SIGUSR2
1006 - move PAM code into its own binary
1007 - when we automatically restart a service, ensure we restart its rdeps, too.
1008 - hide PAM options in fragment parser when compile time disabled
1009 - Support --test based on current system state
1010 - 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().
1011 - after deserializing sockets in socket.c we should reapply sockopts and things
1012 - drop PID 1 reloading, only do reexecing (difficult: Reload()
1013 currently is properly synchronous, Reexec() is weird, because we
1014 cannot delay the response properly until we are back, so instead of
1015 being properly synchronous we just keep open the fd and close it
1016 when done. That means clients do not get a successful method reply,
1017 but much rather a disconnect on success.
1018 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
1019 - when a bus name of a service disappears from the bus make sure to queue further activation requests
1022 - allow port=0 in .socket units
1023 - maybe introduce ExecRestartPre=
1024 - add ReloadSignal= for configuring a reload signal to use
1025 - implement Register= switch in .socket units to enable registration
1026 in Avahi, RPC and other socket registration services.
1027 - allow Type=simple with PIDFile=
1028 https://bugzilla.redhat.com/show_bug.cgi?id=723942
1029 - allow writing multiple conditions in unit files on one line
1030 - load-fragment: when loading a unit file via a chain of symlinks
1031 verify that it is not masked via any of the names traversed.
1032 - introduce Type=pid-file
1033 - introduce mix of BindTo and Requisite
1034 - add a concept of RemainAfterExit= to scope units
1035 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
1038 - Make sure ID_PATH is always exported and complete for
1039 network devices where possible, so we can safely rely
1043 - add support for more attribute types
1044 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
1047 - add more keys to [Route] and [Address] sections
1048 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
1049 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
1050 - add reduced [Link] support to .network files
1051 - add Scope= parsing option for [Network]
1052 - properly handle routerless dhcp leases
1053 - work with non-Ethernet devices
1054 - add support for more bond options
1055 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
1056 - the DHCP lease data (such as NTP/DNS) is still made available when
1057 a carrier is lost on a link. It should be removed instantly.
1058 - expose in the API the following bits:
1059 - option 15, domain name and/or option 119, search list
1060 - option 12, host name and/or option 81, fqdn
1061 - option 123, 144, geolocation
1062 - option 252, configure http proxy (PAC/wpad)
1063 - provide a way to define a per-network interface default metric value
1064 for all routes to it. possibly a second default for DHCP routes.
1065 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
1066 support Name=foo*|bar*|baz ?
1067 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
1068 - allow DUID/IAID to be customized, see issue #394.
1069 - whenever uplink info changes, make DHCP server send out FORCERENEW
1071 * networkd-wait-online:
1072 - make operstates to wait for configurable?
1075 - figure out how much we can increase Maximum Message Size
1078 - add functions to set previously stored IPv6 addresses on startup and get
1079 them at shutdown; store them in client->ia_na
1080 - write more test cases
1081 - implement reconfigure support, see 5.3., 15.11. and 22.20.
1082 - implement support for temporary adressess (IA_TA)
1083 - implement dhcpv6 authentication
1084 - investigate the usefulness of Confirm messages; i.e. are there any
1085 situations where the link changes without any loss in carrier detection
1087 - some servers don't do rapid commit without a filled in IA_NA, verify
1094 - natively watch for dbus-*.service symlinks (PENDING)
1095 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
1097 * fix alsa mixer restore to not print error when no config is stored
1099 * make cryptsetup lower --iter-time
1101 * patch kernel for xattr support in /dev, /proc/, /sys?
1103 * kernel: add device_type = "fb", "fbcon" to class "graphics"
1105 * /usr/bin/service should actually show the new command line
1107 * 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=
