3 * Should systemctl status \* work on all unit types, not just .service?
5 * Dangling symlinks of .automount unit files in .wants/ directories, set up
6 automount points even when the original .automount file did not exist
7 anymore. Only the .mount unit was still around.
9 * ExecStart with unicode characters fails in strv_split_extract:
12 Environment=ONE='one' "TWO='two two' too" THREE=
13 ExecStart=/bin/python3 -c 'import sys;print(sys.argv)' $ONE $TWO $THREE
17 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
19 * wiki: update journal format documentation for lz4 additions
23 * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
27 * Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the
28 other doesn't. What a desaster. Probably to exclude it. Also
29 DECIMAL_STR_WIDTH should probably add an extra "-" into account for negative
32 * port systemctl, systemd-inhibit, busctl, … over to format-table.[ch]'s table formatters
34 * pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up
36 * add --vacuum-xyz options to coredumpctl, matching those journalctl already has.
38 * enforce that transient units are started exactly once only
40 * list the exit codes from the BSD/glibc <sysexits.h> in our own
41 exit-codes.[ch] tables.
43 * SuccessExitStatus= and friends should probably also accept symbolic exit
44 codes names, i.e. error codes from the list maintained in exit-codes.[ch]
46 * introduce Ephemeral= unit file switch, that creates an ephemeral copy of all
47 files and directories that are left writable for a unit, and which are
48 removed after the unit goes down again. A bit like --ephemeral for
49 systemd-nspawn but for system services. If used together with RootImage= this
50 should reflink the image file itself.
52 Related: add Ephemeral=<path1> <path2> … which would allow marking
53 specific paths only like this.
55 * add CopyFile= or so as unit file setting that may be used to copy files or
56 directory trees from the host to te services RootImage= and RootDirectory=
57 environment. Which we can use for /etc/machine-id and in particular
58 /etc/resolv.conf. Should be smart and do something useful on read-only
59 images, for example fallback to read-only bind mounting the file instead.
61 * nspawn's console TTY should be allocated from within the container, not
62 mounted in from the outside
64 * show invocation ID in systemd-run output
66 * bypass SIGTERM state in unit files if KillSignal is SIGKILL
68 * tree-wide: ensure we always block the signals we hook into with
69 sd_event_add_signal() first
71 * add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1
72 and so on, which would mean we could report errors and such.
74 * teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4
77 * introduce DefaultSlice= or so in system.conf that allows changing where we
78 place our units by default, i.e. change system.slice to something
79 else. Similar, ManagerSlice= should exist so that PID1's own scope unit could
80 be moved somewhere else too. Finally machined and logind should get similar
81 options so that it is possible to move user session scopes and machines to a
82 different slice too by default. Usecase: people who want to put resources on
83 the entire system, with the exception of one specific service. See:
84 https://lists.freedesktop.org/archives/systemd-devel/2018-February/040369.html
86 * maybe rework get_user_creds() to query the user database if $SHELL is used
87 for root, but only then.
89 * be stricter with fds we receive for the fdstore: close them asynchronously
91 * calenderspec: add support for week numbers and day numbers within a
92 year. This would allow us to define "bi-weekly" triggers safely.
94 * add bpf-based implementation of devices cgroup controller logic for compat
95 with cgroupsv2 as supported by newest kernel
97 * introduce sd_id128_get_boot_app_specific() which is like
98 sd_id128_get_machine_app_specific(). After all on long-running systems both
99 IDs have similar properties.
101 * sd-bus: add vtable flag, that may be used to request client creds implicitly
102 and asynchronously before dispatching the operation
104 * make use of ethtool veth peer info in machined, for automatically finding out
105 host-side interface pointing to the container.
107 * add some special mode to LogsDirectory=/StateDirectory=… that allows
108 declaring these directories without necessarily pulling in deps for them, or
109 creating them when starting up. That way, we could declare that
110 systemd-journald writes to /var/log/journal, which could be useful when we
111 doing disk usage calculations and so on.
113 * taint systemd if there are fewer than 65536 users assigned (userns) to the system.
115 * deprecate PermissionsStartOnly= and RootDirectoryStartOnly= in favour of the ExecStart= prefix chars
117 * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
118 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
119 as the unit is running or has a job queued.
121 * support projid-based quota in machinectl for containers, and then drop
122 implicit btrfs loopback magic in machined
124 * Add NetworkNamespacePath= to specify a path to a network namespace
126 * maybe use SOURCE_DATE_EPOCH (i.e. the env var the reproducible builds folks
127 introduced) as the RTC epoch, instead of the mtime of NEWS.
129 * add a way to lock down cgroup migration: a boolean, which when set for a unit
130 makes sure the processes in it can never migrate out of it
132 * blog about fd store and restartable services
134 * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
136 * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
137 magic meaning and is no longer upgraded to something else if set explicitly.
139 * in the long run: permit a system with /etc/machine-id linked to /dev/null, to
140 make it lose its identity, i.e. be anonymous. For this we'd have to patch
141 through the whole tree to make all code deal with the case where no machine
144 * optionally, collect cgroup resource data, and store it in per-unit RRD files,
145 suitable for processing with rrdtool. Add bus API to access this data, and
146 possibly implement a CPULoad property based on it.
148 * beef up pam_systemd to take unit file settings such as cgroups properties as
151 * a new "systemd-analyze security" tool outputting a checklist of security
152 features a service does and does not implement
154 * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
155 the quota of a the user indicated in User= via unit file settings, like the
156 other resource management concepts. Would mix nicely with DynamicUser=1. Or
157 alternatively, do this with projids, so that we can also cover services
158 running as root. Quota should probably cover all the special dirs such as
159 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
160 is set, plus the whole disk space any image configured with RootImage=.
162 * Introduce "exit" as an EmergencyAction value, and allow to configure a
163 per-unit success/failure exit code to configure. This would be useful for
164 running commands inside of services inside of containers, which could then
165 propagate their failure state all the way up.
167 * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
168 disks to see if the UID is already in use.
170 * add "systemctl wait" or so, which does what "systemd-run --wait" does, but
171 for all units. It should be both a way to pin units into memory as well as a
172 wait to retrieve their exit data.
174 * maybe set a new set of env vars for services, based on RuntimeDirectory=,
175 StateDirectory=, LogsDirectory=, CacheDirectory= and ConfigurationDirectory=
176 automatically. For example, there could be $RUNTIME_DIRECTORY,
177 $STATE_DIRECTORY, $LOGS_DIRECTORY=, $CACHE_DIRECTORY and
178 $CONFIGURATION_DIRECTORY or so. This could be useful to write services that
179 can adapt to varying directories for these purposes. Special care has to be
180 taken if multiple dirs are configured. Maybe avoid setting the env vars in
183 * expose IO accounting data on the bus, show it in systemd-run --wait and log
184 about it in the resource log message
186 * add "systemctl purge" for flushing out configuration, state, logs, ... of a
187 unit when it is stopped
189 * show whether a service has out-of-date configuration in "systemctl status" by
190 using mtime data of ConfigurationDirectory=.
192 * replace all uses of fgets() + LINE_MAX by read_line()
194 * Add AddUser= setting to unit files, similar to DynamicUser=1 which however
195 creates a static, persistent user rather than a dynamic, transient user. We
196 can leverage code from sysusers.d for this.
198 * add some optional flag to ReadWritePaths= and friends, that has the effect
199 that we create the dir in question when the service is started. Example:
201 ReadWritePaths=:/var/lib/foobar
203 * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
204 the sd-journal logging socket, and, if the timeout is set to 0, sets
205 O_NONBLOCK on it. That way people can control if and when to block for
208 * hostnamed: populate form factor data from a new hwdb database, so that old
209 yogas can be recognized as "convertible" too, even if they predate the DMI
210 "convertible" form factor
212 * Maybe add a small tool invoked early at boot, that adds in or resizes
213 partitions automatically, to be used when the media used is actually larger
214 than the image written onto it is.
216 * Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
217 after all. Be strict however, only support the equivalent of nspawn's
218 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
221 * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
222 the service cgroup, which is supposed to monitor the service, and when it
223 exits the service is considered failed by its monitor.
225 * track the per-service PAM process properly (i.e. as an additional control
226 process), so that it may be queried on the bus and everything.
228 * add a new "debug" job mode, that is propagated to unit_start() and for
229 services results in two things: we raise SIGSTOP right before invoking
230 execve() and turn off watchdog support. Then, use that to implement
231 "systemd-gdb" for attaching to the start-up of any system service in its
234 * maybe introduce gpt auto discovery for /var/tmp?
236 * maybe add gpt-partition-based user management: each user gets his own
237 LUKS-encrypted GPT partition with a new GPT type. A small nss module
238 enumerates users via udev partition enumeration. UIDs are assigned in a fixed
239 way: the partition index is added as offset to some fixed base uid. User name
240 is stored in GPT partition name. A PAM module authenticates the user via the
241 LUKS partition password. Benefits: strong per-user security, compatibility
242 with stateless/read-only/verity-enabled root. (other idea: do this based on
243 loopback files in /home, without GPT involvement)
245 * gpt-auto logic: introduce support for discovering /var matching an image. For
246 that, use a partition type UUID that is hashed from the OS name (as encoded
247 in /etc/os-release), the architecture, and 4 new bits from the gpt flags
248 field of the root partition. This way can easily support multiple OS
249 installations on the same GPT partition table, without problems with
250 unmatched /var partitions.
252 * gpt-auto logic: related to the above, maybe support a "secondary" root
253 partition, that is mounted to / and is writable, and where the actual root's
254 /usr is mounted into.
256 * 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
258 * drop nss-myhostname in favour of nss-resolve?
260 * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
261 then use that for the setting used in user@.service. It should be understood
262 relative to the configured default value.
264 * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
266 * enable LockMLOCK to take a percentage value relative to physical memory
268 * Permit masking specific netlink APIs with RestrictAddressFamily=
270 * nspawn: support that /proc, /sys/, /dev are pre-mounted
272 * define gpt header bits to select volatility mode
274 * ProtectKernelLogs= (drops CAP_SYSLOG, add seccomp for syslog() syscall, and DeviceAllow to /dev/kmsg) in service files
276 * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
278 * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
280 * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
282 * ProtectKeyRing= to take keyring calls away
284 * RemoveKeyRing= to remove all keyring entries of the specified user
286 * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
287 on PID 1 with the relevant signals, and makes relevant files in /sys and
288 /proc (such as the sysrq stuff) unavailable
290 * DeviceAllow= should also generate seccomp filters for mknod()
292 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
294 * journalctl: make sure -f ends when the container indicated by -M terminates
296 * mount: automatically search for "main" partition of an image has multiple
299 * expose the "privileged" flag of ExecCommand on the bus, and open it up to
302 * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
303 find a way to map the User=/Group= of the service to the right name. This way
304 a user/group for a service only has to exist on the host for the right
307 * add bus API for creating unit files in /etc, reusing the code for transient units
309 * add bus API to remove unit files from /etc
311 * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
313 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
314 kernel doesn't support linkat() that replaces existing files, currently)
316 * check if DeviceAllow= should split first, resolve specifiers later
318 * transient units: don't bother with actually setting unit properties, we
319 reload the unit file anyway
321 * journald: sigbus API via a signal-handler safe function that people may call
322 from the SIGBUS handler
324 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
326 * resolved: when routing queries, make sure only look for the *longest* suffix...
328 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
329 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
331 * cache sd_event_now() result from before the first iteration...
333 * add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction
335 * PID1: find a way how we can reload unit file configuration for
336 specific units only, without reloading the whole of systemd
338 * add an explicit parser for LimitRTPRIO= that verifies
339 the specified range and generates sane error messages for incorrect
342 * when we detect that there are waiting jobs but no running jobs, do something
344 * push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
346 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
348 * there's probably something wrong with having user mounts below /sys,
349 as we have for debugfs. for exmaple, src/core/mount.c handles mounts
350 prefixed with /sys generally special.
351 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
353 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
355 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
357 * add a job mode that will fail if a transaction would mean stopping
358 running units. Use this in timedated to manage the NTP service
360 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
362 * Maybe add support for the equivalent of "ethtool advertise" to .link files?
363 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
365 * The udev blkid built-in should expose a property that reflects
366 whether media was sensed in USB CF/SD card readers. This should then
367 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
368 picked up by systemd unless they contain a medium. This would mirror
369 the behaviour we already have for CD drives.
371 * networkd/udev: implement SR_IOV configuration in .link files:
372 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
374 * hostnamectl: show root image uuid
376 * sysfs set api in libudev is not const
378 * Find a solution for SMACK capabilities stuff:
379 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
381 * "systemctl preset-all" should probably order the unit files it
382 operates on lexicographically before starting to work, in order to
383 ensure deterministic behaviour if two unit files conflict (like DMs
386 * synchronize console access with BSD locks:
387 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
389 * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
390 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
392 * in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
394 * figure out when we can use the coarse timers
396 * add "systemctl start -v foobar.service" that shows logs of a service
397 while the start command runs. This is non-trivial to do without
398 races though, since we should flush out all journal messages before
399 returning from the "systemctl stop".
401 * 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
403 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
405 * introduce systemd-timesync-wait.service or so to sync on an NTP fix?
407 * consider showing the unit names during boot up in the status output, not just the unit descriptions
409 * maybe allow timer units with an empty Units= setting, so that they
410 can be used for resuming the system but nothing else.
412 * what to do about udev db binary stability for apps? (raw access is not an option)
414 * man: maybe use the word "inspect" rather than "introspect"?
416 * systemctl: if some operation fails, show log output?
418 * systemctl edit: use equvalent of cat() to insert existing config as a comment, prepended with #.
419 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
421 * exponential backoff in timesyncd when we cannot reach a server
423 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
425 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
427 * systemd.show_status= should probably have a mode where only failed
430 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
431 (throughout the codebase, not only PID1)
435 - service registration
436 - service/domain/types browsing
438 - DNS-SD service registration from socket units
439 - resolved should optionally register additional per-interface LLMNR
440 names, so that for the container case we can establish the same name
441 (maybe "host") for referencing the server, everywhere.
442 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
443 - hook up resolved with machined-based address resolution
445 * refcounting in sd-resolve is borked
447 * Add a new verb "systemctl top"
449 * add new gpt type for btrfs volumes
451 * support empty /etc boots nicely:
452 - nspawn/gpt-generator: introduce new gpt partition type for /usr
454 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
456 * a way for container managers to turn off getty starting via $container_headless= or so...
458 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
460 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
461 they run added to the initial transaction and thus confuse Type=idle.
463 * add bus api to query unit file's X fields.
465 * gpt-auto-generator:
466 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
467 - Make /home automount rather than mount?
469 * add generator that pulls in systemd-network from containers when
470 CAP_NET_ADMIN is set, more than the loopback device is defined, even
471 when it is otherwise off
473 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
475 * implement Distribute= in socket units to allow running multiple
476 service instances processing the listening socket, and open this up
479 * socket units: support creating sockets in different namespace,
480 opening it up for JoinsNamespaceOf=. This would require to fork off
481 a tiny process that joins the namespace and creates/binds the socket
482 and passes this back to PID1 via SCM_RIGHTS. This also could be used
483 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
485 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
486 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
487 should SIGSTOP all unit processes in a loop until all processes of
488 it are fully stopped. This can later be used for app management by
489 desktop UIs such as gnome-shell to freeze apps that are not visible
490 on screen, not unlike how job control works on the shell
493 - implement per-slice CPUFairScheduling=1 switch
494 - handle jointly mounted controllers correctly
495 - introduce high-level settings for RT budget, swappiness
496 - how to reset dynamically changed unit cgroup attributes sanely?
497 - when reloading configuration, apply new cgroup configuration
498 - when recursively showing the cgroup hierarchy, optionally also show
499 the hierarchies of child processes
502 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
503 - ensure scope units may be started only a single time
505 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
507 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
509 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
511 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
513 * 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
515 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
517 * If we try to find a unit via a dangling symlink, generate a clean
518 error. Currently, we just ignore it and read the unit from the search
521 * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
523 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
525 * load .d/*.conf dropins for device units
527 * allow implementation of InaccessibleDirectories=/ plus
528 ReadOnlyDirectories=... for whitelisting files for a service.
532 - GetAllProperties() on a non-existing object does not result in a failure currently
533 - port to sd-resolve for connecting to TCP dbus servers
534 - 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
535 - see if we can drop more message validation on the sending side
536 - add API to clone sd_bus_message objects
537 - longer term: priority inheritance
539 - NameLost/NameAcquired obsolete
542 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
545 - allow multiple signal handlers per signal?
546 - document chaining of signal handler for SIGCHLD and child handlers
547 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
548 - generate a failure of a default event loop is executed out-of-thread
549 - maybe add support for inotify events
551 * investigate endianness issues of UUID vs. GUID
553 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
554 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
556 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
558 * add a pam module that on password changes updates any LUKS slot where the password matches
560 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
563 - add unit tests for config_parse_device_allow()
565 * seems that when we follow symlinks to units we prefer the symlink
566 destination path over /etc and /usr. We should not do that. Instead
567 /etc should always override /run+/usr and also any symlink
570 * when isolating, try to figure out a way how we implicitly can order
571 all units we stop before the isolating unit...
573 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
575 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
576 that the boot loader should be installed to the ESP. Define a way
577 how an installer can figure out whether a BLS compliant boot loader
580 * think about requeuing jobs when daemon-reload is issued? usecase:
581 the initrd issues a reload after fstab from the host is accessible
582 and we might want to requeue the mounts local-fs acquired through
585 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
587 * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
589 * shutdown logging: store to EFI var, and store to USB stick?
591 * merge unit_kill_common() and unit_kill_context()
593 * introduce ExecCondition= in services
596 - honor language efi variables for default language selection (if there are any?)
597 - honor timezone efi variables for default timezone selection (if there are any?)
598 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
600 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
602 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
604 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
607 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
608 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
609 - logind: wakelock/opportunistic suspend support
610 - Add pretty name for seats in logind
611 - logind: allow showing logout dialog from system?
612 - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
613 - session scopes/user unit: add RequiresMountsFor for the home directory of the user
614 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
615 - if pam_systemd is invoked by su from a process that is outside of a
616 any session we should probably just become a NOP, since that's
617 usually not a real user session but just some system code that just
619 - logind: make the Suspend()/Hibernate() bus calls wait for the for
620 the job to be completed. before returning, so that clients can wait
621 for "systemctl suspend" to finish to know when the suspending is
623 - logind: when the power button is pressed short, just popup a
624 logout dialog. If it is pressed for 1s, do the usual
625 shutdown. Inspiration are Macs here.
626 - expose "Locked" property on logind sesison objects
627 - given that logind now lets PID 1 do all nasty work, we can
628 probably reduce the capability set it retains substantially.
629 (we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
630 - expose orientation sensors and tablet mode through logind
631 - maybe allow configuration of the StopTimeout for session scopes
632 - rename session scope so that it includes the UID. THat way
633 the session scope can be arranged freely in slices and we don't have
634 make assumptions about their slice anymore.
635 - follow PropertiesChanged state more closely, to deal with quick logouts and
638 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
641 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
642 - import and delete pstore filesystem content at startup
643 - journald: also get thread ID from client, plus thread name
644 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
645 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
646 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
647 - declare the local journal protocol stable in the wiki interface chart
648 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
649 - journald: when dropping msgs due to ratelimit make sure to write
650 "dropped %u messages" not only when we are about to print the next
651 message that works, but alraedy after a short tiemout
652 - check if we can make journalctl by default use --follow mode inside of less if called without args?
653 - maybe add API to send pairs of iovecs via sd_journal_send
654 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
655 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
656 and !FOOBAR for events without FOOBAR.
657 - journal: store timestamp of journal_file_set_offline() int he header,
658 so it is possible to display when the file was last synced.
659 - 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.
660 - journal: find a way to allow dropping history early, based on priority, other rules
661 - journal: When used on NFS, check payload hashes
662 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
663 - refuse taking lower-case variable names in sd_journal_send() and friends.
664 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
665 - journal: deal nicely with byte-by-byte copied files, especially regards header
666 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
667 - Replace utmp, wtmp, btmp, and lastlog completely with journal
668 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
669 - when a kernel driver logs in a tight loop, we should ratelimit that too.
670 - journald: optionally, log debug messages to /run but everything else to /var
671 - journald: when we drop syslog messages because the syslog socket is
672 full, make sure to write how many messages are lost as first thing
673 to syslog when it works again.
674 - change systemd-journal-flush into a service that stays around during
675 boot, and causes the journal to be moved back to /run on shutdown,
676 so that we do not keep /var busy. This needs to happen synchronously,
677 hence doing this via signals is not going to work.
678 - optionally support running journald from the command line for testing purposes in external projects
679 - journald: allow per-priority and per-service retention times when rotating/vacuuming
680 - journald: make use of uid-range.h to managed uid ranges to split
682 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
683 - improve journalctl performance by loading journal files
684 lazily. Encode just enough information in the file name, so that we
685 do not have to open it to know that it is not interesting for us, for
686 the most common operations.
687 - journal-or-kmsg is currently broken? See reverted
688 commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
689 - man: document that corrupted journal files is nothing to act on
690 - rework journald sigbus stuff to use mutex
691 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
692 services that run under their own user ids, and use User= (but only
693 in a world where userns is ubiquitous since otherwise we cannot
694 invoke those daemons on the host AND in a container anymore). Also,
695 if LimitNPROC= is used without User= we should warn and refuse
697 - journalctl --verify: don't show files that are currently being
698 written to as FAIL, but instead show that their are being written to.
699 - add journalctl -H that talks via ssh to a remote peer and passes through
701 - add a version of --merge which also merges /var/log/journal/remote
702 - journalctl: -m should access container journals directly by enumerating
703 them via machined, and also watch containers coming and going.
704 Benefit: nspawn --ephemeral would start working nicely with the journal.
705 - assign MESSAGE_ID to log messages about failed services
707 * add a test if all entries in the catalog are properly formatted.
708 (Adding dashes in a catalog entry currently results in the catalog entry
709 being silently skipped. journalctl --update-catalog must warn about this,
710 and we should also have a unit test to check that all our message are OK.)
713 - document that deps in [Unit] sections ignore Alias= fields in
714 [Install] units of other units, unless those units are disabled
715 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
716 - document that service reload may be implemented as service reexec
717 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
718 - document systemd-journal-flush.service properly
719 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
720 - man: document the very specific env the shutdown drop-in tools live in
721 - man: add more examples to man pages
722 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
725 - add systemctl switch to dump transaction without executing it
726 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
727 - "systemctl disable" on a static unit prints no message and does
728 nothing. "systemctl enable" does nothing, and gives a bad message
729 about it. Should fix both to print nice actionable messages.
730 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
731 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
732 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
733 - systemctl: "Journal has been rotated since unit was started." message is misleading
734 - systemctl status output should include list of triggering units and their status
737 - "systemctl mask" should find all names by which a unit is accessible
738 (i.e. by scanning for symlinks to it) and link them all to /dev/null
741 - timer units should get the ability to trigger when:
742 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
744 - Modulate timer frequency based on battery state
746 * add libsystemd-password or so to query passwords during boot using the password agent logic
748 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
750 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
752 * make repeated alt-ctrl-del presses printing a dump
754 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
756 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
759 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
760 with seccomp. That should provide us with a useful log buffer that
761 systemd can log to during early boot, and disconnect container logs
762 from the kernel's logs.
763 - as soon as networkd has a bus interface, hook up --network-interface=,
764 --network-bridge= with networkd, to trigger netdev creation should an
766 - a nice way to boot up without machine id set, so that it is set at boot
767 automatically for supporting --ephemeral. Maybe hash the host machine id
768 together with the machine name to generate the machine id for the container
769 - fix logic always print a final newline on output.
770 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
771 - should optionally support receiving WATCHDOG=1 messages from its payload
773 - optionally automatically add FORWARD rules to iptables whenever nspawn is
774 running, remove them when shut down.
775 - maybe make copying of /etc/resolv.conf optional, and skip it if --read-only
779 - refuse mounting over a mount point
780 - automatically discover .roothash files in dissect, similarly to nspawn
783 - add an API so that libvirt-lxc can inform us about network interfaces being
784 removed or added to an existing machine
785 - "machinectl migrate" or similar to copy a container from or to a
786 difference host, via ssh
787 - introduce systemd-nspawn-ephemeral@.service, and hook it into
788 "machinectl start" with a new --ephemeral switch
789 - "machinectl status" should also show internal logs of the container in
791 - "machinectl list-images" should show os-release data, as well as
792 machine-info data (including deployment level)
793 - "machinectl history"
795 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
796 shell in it, and marks it read-only after use
799 - generate a nice warning if mkfs.btrfs is missing
802 - cryptsetup-generator: allow specification of passwords in crypttab itself
803 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
805 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
806 https://bugs.freedesktop.org/show_bug.cgi?id=54712
808 * add a dependency on standard-conf.xml and other included files to man pages
810 * MountFlags=shared acts as MountFlags=slave right now.
812 * properly handle loop back mounts via fstab, especially regards to fsck/passno
814 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
819 - add trigger --subsystem-match=usb/usb_device device
820 - reimport udev db after MOVE events for devices without dev_t
822 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
824 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
827 - save coredump in Windows/Mozilla minidump format
828 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
830 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
832 * default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max
834 * be able to specify a forced restart of service A where service B depends on, in case B
835 needs to be auto-respawned?
838 - apply "x" on "D" too (see patch from William Douglas)
840 - instead of ignoring unknown fields, reject them.
841 - creating new directories/subvolumes/fifos/device nodes
842 should not follow symlinks. None of the other adjustment or creation
843 calls follow symlinks.
845 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
847 * verify that the AF_UNIX sockets of a service in the fs still exist
848 when we start a service in order to avoid confusion when a user
849 assumes starting a service is enough to make it accessible
851 * Make it possible to set the keymap independently from the font on
852 the kernel cmdline. Right now setting one resets also the other.
854 * and a dbus call to generate target from current state
856 * write blog stories about:
857 - hwdb: what belongs into it, lsusb
858 - enabling dbus services
859 - how to make changes to sysctl and sysfs attributes
861 - how to pass throw-away units to systemd, or dynamically change properties of existing units
862 - testing with Harald's awesome test kit
864 - how to develop against journal browsing APIs
865 - the journal HTTP iface
866 - non-cgroup resource management
867 - dynamic resource management with cgroups
868 - refreshed, longer missions statement
869 - calendar time events
870 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
871 - how to create your own target
872 - instantiated apache, dovecot and so on
873 - hooking a script into various stages of shutdown/rearly booot
875 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
877 * dot output for --test showing the 'initial transaction'
880 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
881 log both units as UNIT=, so that journalctl -u triggers on both.
882 - generate better errors when people try to set transient properties
883 that are not supported...
884 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
885 - maybe introduce WantsMountsFor=? Usecase:
886 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
887 - recreate systemd's D-Bus private socket file on SIGUSR2
888 - move PAM code into its own binary
889 - when we automatically restart a service, ensure we restart its rdeps, too.
890 - hide PAM options in fragment parser when compile time disabled
891 - Support --test based on current system state
892 - 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().
893 - after deserializing sockets in socket.c we should reapply sockopts and things
894 - drop PID 1 reloading, only do reexecing (difficult: Reload()
895 currently is properly synchronous, Reexec() is weird, because we
896 cannot delay the response properly until we are back, so instead of
897 being properly synchronous we just keep open the fd and close it
898 when done. That means clients do not get a successful method reply,
899 but much rather a disconnect on success.
900 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
901 - when a bus name of a service disappears from the bus make sure to queue further activation requests
904 - allow port=0 in .socket units
905 - maybe introduce ExecRestartPre=
906 - add ReloadSignal= for configuring a reload signal to use
907 - implement Register= switch in .socket units to enable registration
908 in Avahi, RPC and other socket registration services.
909 - allow Type=simple with PIDFile=
910 https://bugzilla.redhat.com/show_bug.cgi?id=723942
911 - allow writing multiple conditions in unit files on one line
912 - load-fragment: when loading a unit file via a chain of symlinks
913 verify that it is not masked via any of the names traversed.
914 - introduce Type=pid-file
915 - introduce mix of BindTo and Requisite
916 - add a concept of RemainAfterExit= to scope units
917 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
920 - Make sure ID_PATH is always exported and complete for
921 network devices where possible, so we can safely rely
923 - check MTUBytes parsing (expecting size_t but we are using unsigned)
926 - add support for more attribute types
927 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
930 - add more keys to [Route] and [Address] sections
931 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
932 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
933 - add reduced [Link] support to .network files
934 - add Scope= parsing option for [Network]
935 - properly handle routerless dhcp leases
936 - work with non-Ethernet devices
937 - add support for more bond options
938 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
939 - the DHCP lease data (such as NTP/DNS) is still made available when
940 a carrier is lost on a link. It should be removed instantly.
941 - expose in the API the following bits:
942 - option 15, domain name and/or option 119, search list
943 - option 12, host name and/or option 81, fqdn
944 - option 123, 144, geolocation
945 - option 252, configure http proxy (PAC/wpad)
946 - provide a way to define a per-network interface default metric value
947 for all routes to it. possibly a second default for DHCP routes.
948 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
949 support Name=foo*|bar*|baz ?
950 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
951 - allow DUID/IAID to be customized, see issue #394.
952 - whenever uplink info changes, make DHCP server send out FORCERENEW
954 * networkd-wait-online:
955 - make operstates to wait for configurable?
958 - figure out how much we can increase Maximum Message Size
961 - add functions to set previously stored IPv6 addresses on startup and get
962 them at shutdown; store them in client->ia_na
963 - write more test cases
964 - implement reconfigure support, see 5.3., 15.11. and 22.20.
965 - implement support for temporary adressess (IA_TA)
966 - implement dhcpv6 authentication
967 - investigate the usefulness of Confirm messages; i.e. are there any
968 situations where the link changes without any loss in carrier detection
970 - some servers don't do rapid commit without a filled in IA_NA, verify
977 - natively watch for dbus-*.service symlinks (PENDING)
978 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
980 * fix alsa mixer restore to not print error when no config is stored
982 * make cryptsetup lower --iter-time
984 * patch kernel for xattr support in /dev, /proc/, /sys?
986 * kernel: add device_type = "fb", "fbcon" to class "graphics"
988 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
990 * /usr/bin/service should actually show the new command line
992 * 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=
994 * fedora: F20: go timer units all the way, leave cron.daily for cron
996 * neither pkexec nor sudo initialize environ[] from the PAM environment?
998 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
1000 * register catalog database signature as file magic
1002 * zsh shell completion:
1003 - <command> <verb> -<TAB> should complete options, but currently does not
1004 - systemctl add-wants,add-requires
1009 * look for close() vs. close_nointr() vs. close_nointr_nofail()
1011 * check for strerror(r) instead of strerror(-r)
1015 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
1017 * use secure_getenv() instead of getenv() where appropriate
1019 * link up selected blog stories from man pages and unit files Documentation= fields
