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 * block setrlimit(RLIMIT_NOPROC) (and other per-user limits) in nspawn when userns is not on
29 * nss-systemd: implement enumeration, that shows all dynamic users plus the
30 synthesized ones if necessary, so that "getent passwd" shows useful data.
32 * teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4
35 * introduce DefaultSlice= or so in system.conf that allows changing where we
36 place our units by default, i.e. change system.slice to something
37 else. Similar, ManagerSlice= should exist so that PID1's own scope unit could
38 be moved somewhere else too. Finally machined and logind should get similar
39 options so that it is possible to move user session scopes and machines to a
40 different slice too by default. Usecase: people who want to put resources on
41 the entire system, with the exception of one specific service. See:
42 https://lists.freedesktop.org/archives/systemd-devel/2018-February/040369.html
44 * maybe rework get_user_creds() to query the user database if $SHELL is used
45 for root, but only then.
47 * there should be path_hash_ops and we should use it in tmpfiles' hashmap object to deal with identical but differently spelt paths
49 * be stricter with fds we receive for the fdstore: close them asynchronously
51 * calenderspec: add support for week numbers and day numbers within a
52 year. This would allow us to define "bi-weekly" triggers safely.
54 * add support for recursive bpf firewalling as supported by the newest kernel
56 * add bpf-based implementation of devices cgroup controller logic for compat with cgroupsv2 as supported by newest kernel
58 * introduce sd_id128_get_boot_app_specific() which is like
59 sd_id128_get_machine_app_specific(). After all on long-running systems both
60 IDs have similar properties.
62 * sd-bus: add vtable flag, that may be used to request client creds implicitly
63 and asynchronously before dispatching the operation
65 * implement transient socket unit.
67 * make use of ethtool veth peer info in machined, for automatically finding out
68 host-side interface pointing to the container.
70 * add some special mode to LogsDirectory=/StateDirectory=… that allows
71 declaring these directories without necessarily pulling in deps for them, or
72 creating them when starting up. That way, we could declare that
73 systemd-journald writes to /var/log/journal, which could be useful when we
74 doing disk usage calculations and so on.
76 * taint systemd if there are fewer than 65536 users assigned to the system.
78 * deprecate PermissionsStartOnly= and RootDirectoryStartOnly= in favour of the ExecStart= prefix chars
80 * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
81 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
82 as the unit is running or has a job queued.
84 * support projid-based quota in machinectl for containers, and then drop
85 implicit btrfs loopback magic in machined
87 * Add NetworkNamespacePath= to specify a path to a network namespace
89 * maybe use SOURCE_DATE_EPOCH (i.e. the env var the reproducible builds folks
90 introduced) as the RTC epoch, instead of the mtime of NEWS.
92 * add a way to lock down cgroup migration: a boolean, which when set for a unit
93 makes sure the processes in it can never migrate out of it
95 * blog about fd store and restartable services
97 * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
99 * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
100 magic meaning and is no longer upgraded to something else if set explicitly.
102 * in the long run: permit a system with /etc/machine-id linked to /dev/null, to
103 make it lose its identity, i.e. be anonymous. For this we'd have to patch
104 through the whole tree to make all code deal with the case where no machine
107 * optionally, collect cgroup resource data, and store it in per-unit RRD files,
108 suitable for processing with rrdtool. Add bus API to access this data, and
109 possibly implement a CPULoad property based on it.
111 * beef up pam_systemd to take unit file settings such as cgroups properties as
114 * a new "systemd-analyze security" tool outputting a checklist of security
115 features a service does and does not implement
117 * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
118 the quota of a the user indicated in User= via unit file settings, like the
119 other resource management concepts. Would mix nicely with DynamicUser=1. Or
120 alternatively, do this with projids, so that we can also cover services
121 running as root. Quota should probably cover all the special dirs such as
122 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
123 is set, plus the whole disk space any image configured with RootImage=.
125 * Introduce "exit" as an EmergencyAction value, and allow to configure a
126 per-unit success/failure exit code to configure. This would be useful for
127 running commands inside of services inside of containers, which could then
128 propagate their failure state all the way up.
130 * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
131 disks to see if the UID is already in use.
133 * add dissect_image_warn() as a wrapper around dissect_image() that prints
134 friendly log messages for the returned errors, so that we don't have to
135 duplicate that in nspawn, systemd-dissect and PID 1.
137 * add "systemctl wait" or so, which does what "systemd-run --wait" does, but
138 for all units. It should be both a way to pin units into memory as well as a
139 wait to retrieve their exit data.
141 * maybe set a new set of env vars for services, based on RuntimeDirectory=,
142 StateDirectory=, LogsDirectory=, CacheDirectory= and ConfigurationDirectory=
143 automatically. For example, there could be $RUNTIME_DIRECTORY,
144 $STATE_DIRECTORY, $LOGS_DIRECTORY=, $CACHE_DIRECTORY and
145 $CONFIGURATION_DIRECTORY or so. This could be useful to write services that
146 can adapt to varying directories for these purposes. Special care has to be
147 taken if multiple dirs are configured. Maybe avoid setting the env vars in
150 * expose IO accounting data on the bus, show it in systemd-run --wait and log
151 about it in the resource log message
153 * add "systemctl purge" for flushing out configuration, state, logs, ... of a
154 unit when it is stopped
156 * show whether a service has out-of-date configuration in "systemctl status" by
157 using mtime data of ConfigurationDirectory=.
159 * replace all uses of fgets() + LINE_MAX by read_line()
161 * Add AddUser= setting to unit files, similar to DynamicUser=1 which however
162 creates a static, persistent user rather than a dynamic, transient user. We
163 can leverage code from sysusers.d for this.
165 * add some optional flag to ReadWritePaths= and friends, that has the effect
166 that we create the dir in question when the service is started. Example:
168 ReadWritePaths=:/var/lib/foobar
170 * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
171 the sd-journal logging socket, and, if the timeout is set to 0, sets
172 O_NONBLOCK on it. That way people can control if and when to block for
175 * hostnamed: populate form factor data from a new hwdb database, so that old
176 yogas can be recognized as "convertible" too, even if they predate the DMI
177 "convertible" form factor
179 * Maybe add a small tool invoked early at boot, that adds in or resizes
180 partitions automatically, to be used when the media used is actually larger
181 than the image written onto it is.
183 * Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
184 after all. Be strict however, only support the equivalent of nspawn's
185 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
188 * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
189 the service cgroup, which is supposed to monitor the service, and when it
190 exits the service is considered failed by its monitor.
192 * track the per-service PAM process properly (i.e. as an additional control
193 process), so that it may be queried on the bus and everything.
195 * add a new "debug" job mode, that is propagated to unit_start() and for
196 services results in two things: we raise SIGSTOP right before invoking
197 execve() and turn off watchdog support. Then, use that to implement
198 "systemd-gdb" for attaching to the start-up of any system service in its
201 * maybe introduce gpt auto discovery for /var/tmp?
203 * maybe add gpt-partition-based user management: each user gets his own
204 LUKS-encrypted GPT partition with a new GPT type. A small nss module
205 enumerates users via udev partition enumeration. UIDs are assigned in a fixed
206 way: the partition index is added as offset to some fixed base uid. User name
207 is stored in GPT partition name. A PAM module authenticates the user via the
208 LUKS partition password. Benefits: strong per-user security, compatibility
209 with stateless/read-only/verity-enabled root. (other idea: do this based on
210 loopback files in /home, without GPT involvement)
212 * gpt-auto logic: introduce support for discovering /var matching an image. For
213 that, use a partition type UUID that is hashed from the OS name (as encoded
214 in /etc/os-release), the architecture, and 4 new bits from the gpt flags
215 field of the root partition. This way can easily support multiple OS
216 installations on the same GPT partition table, without problems with
217 unmatched /var partitions.
219 * gpt-auto logic: related to the above, maybe support a "secondary" root
220 partition, that is mounted to / and is writable, and where the actual root's
221 /usr is mounted into.
223 * 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
225 * drop nss-myhostname in favour of nss-resolve?
227 * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
228 then use that for the setting used in user@.service. It should be understood
229 relative to the configured default value.
231 * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
233 * enable LockMLOCK to take a percentage value relative to physical memory
235 * Permit masking specific netlink APIs with RestrictAddressFamily=
237 * nspawn: support that /proc, /sys/, /dev are pre-mounted
239 * define gpt header bits to select volatility mode
241 * ProtectKernelLogs= (drops CAP_SYSLOG, add seccomp for syslog() syscall, and DeviceAllow to /dev/kmsg) in service files
243 * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
245 * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
247 * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
249 * ProtectKeyRing= to take keyring calls away
251 * RemoveKeyRing= to remove all keyring entries of the specified user
253 * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
254 on PID 1 with the relevant signals, and makes relevant files in /sys and
255 /proc (such as the sysrq stuff) unavailable
257 * DeviceAllow= should also generate seccomp filters for mknod()
259 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
261 * journalctl: make sure -f ends when the container indicated by -M terminates
263 * mount: automatically search for "main" partition of an image has multiple
266 * expose the "privileged" flag of ExecCommand on the bus, and open it up to
269 * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
270 find a way to map the User=/Group= of the service to the right name. This way
271 a user/group for a service only has to exist on the host for the right
274 * add bus API for creating unit files in /etc, reusing the code for transient units
276 * add bus API to remove unit files from /etc
278 * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
280 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
281 kernel doesn't support linkat() that replaces existing files, currently)
283 * check if DeviceAllow= should split first, resolve specifiers later
285 * transient units: don't bother with actually setting unit properties, we
286 reload the unit file anyway
288 * journald: sigbus API via a signal-handler safe function that people may call
289 from the SIGBUS handler
291 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
293 * resolved: when routing queries, make sure only look for the *longest* suffix...
295 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
296 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
298 * cache sd_event_now() result from before the first iteration...
300 * add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction
302 * PID1: find a way how we can reload unit file configuration for
303 specific units only, without reloading the whole of systemd
305 * add an explicit parser for LimitRTPRIO= that verifies
306 the specified range and generates sane error messages for incorrect
309 * when we detect that there are waiting jobs but no running jobs, do something
311 * push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
313 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
315 * there's probably something wrong with having user mounts below /sys,
316 as we have for debugfs. for exmaple, src/core/mount.c handles mounts
317 prefixed with /sys generally special.
318 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
320 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
322 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
324 * add a job mode that will fail if a transaction would mean stopping
325 running units. Use this in timedated to manage the NTP service
327 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
329 * Maybe add support for the equivalent of "ethtool advertise" to .link files?
330 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
332 * The udev blkid built-in should expose a property that reflects
333 whether media was sensed in USB CF/SD card readers. This should then
334 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
335 picked up by systemd unless they contain a medium. This would mirror
336 the behaviour we already have for CD drives.
338 * networkd/udev: implement SR_IOV configuration in .link files:
339 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
341 * Rework systemctl's GetAll property parsing to use the generic bus_map_all_properties() API
343 * Port various tools to make use of verbs.[ch], where applicable: busctl,
344 coredumpctl, hostnamectl, localectl, timedatectl
346 * hostnamectl: show root image uuid
348 * sysfs set api in libudev is not const
350 * Find a solution for SMACK capabilities stuff:
351 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
353 * "systemctl preset-all" should probably order the unit files it
354 operates on lexicographically before starting to work, in order to
355 ensure deterministic behaviour if two unit files conflict (like DMs
358 * synchronize console access with BSD locks:
359 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
361 * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
362 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
364 * in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
366 * figure out when we can use the coarse timers
368 * add "systemctl start -v foobar.service" that shows logs of a service
369 while the start command runs. This is non-trivial to do without
370 races though, since we should flush out all journal messages before
371 returning from the "systemctl stop".
373 * 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
375 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
377 * introduce systemd-timesync-wait.service or so to sync on an NTP fix?
379 * consider showing the unit names during boot up in the status output, not just the unit descriptions
381 * maybe allow timer units with an empty Units= setting, so that they
382 can be used for resuming the system but nothing else.
384 * what to do about udev db binary stability for apps? (raw access is not an option)
386 * man: maybe use the word "inspect" rather than "introspect"?
388 * systemctl: if some operation fails, show log output?
390 * systemctl edit: use equvalent of cat() to insert existing config as a comment, prepended with #.
391 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
393 * exponential backoff in timesyncd when we cannot reach a server
395 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
397 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
399 * systemd.show_status= should probably have a mode where only failed
402 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
403 (throughout the codebase, not only PID1)
407 - service registration
408 - service/domain/types browsing
410 - DNS-SD service registration from socket units
411 - resolved should optionally register additional per-interface LLMNR
412 names, so that for the container case we can establish the same name
413 (maybe "host") for referencing the server, everywhere.
414 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
415 - hook up resolved with machined-based address resolution
417 * refcounting in sd-resolve is borked
419 * Add a new verb "systemctl top"
421 * add new gpt type for btrfs volumes
423 * support empty /etc boots nicely:
424 - nspawn/gpt-generator: introduce new gpt partition type for /usr
426 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
428 * a way for container managers to turn off getty starting via $container_headless= or so...
430 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
432 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
433 they run added to the initial transaction and thus confuse Type=idle.
435 * add bus api to query unit file's X fields.
437 * gpt-auto-generator:
438 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
439 - Make /home automount rather than mount?
441 * add generator that pulls in systemd-network from containers when
442 CAP_NET_ADMIN is set, more than the loopback device is defined, even
443 when it is otherwise off
445 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
447 * implement Distribute= in socket units to allow running multiple
448 service instances processing the listening socket, and open this up
451 * socket units: support creating sockets in different namespace,
452 opening it up for JoinsNamespaceOf=. This would require to fork off
453 a tiny process that joins the namespace and creates/binds the socket
454 and passes this back to PID1 via SCM_RIGHTS. This also could be used
455 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
457 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
458 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
459 should SIGSTOP all unit processes in a loop until all processes of
460 it are fully stopped. This can later be used for app management by
461 desktop UIs such as gnome-shell to freeze apps that are not visible
462 on screen, not unlike how job control works on the shell
465 - implement per-slice CPUFairScheduling=1 switch
466 - handle jointly mounted controllers correctly
467 - introduce high-level settings for RT budget, swappiness
468 - how to reset dynamically changed unit cgroup attributes sanely?
469 - when reloading configuration, apply new cgroup configuration
470 - when recursively showing the cgroup hierarchy, optionally also show
471 the hierarchies of child processes
474 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
475 - ensure scope units may be started only a single time
477 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
479 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
481 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
483 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
485 * 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
487 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
489 * If we try to find a unit via a dangling symlink, generate a clean
490 error. Currently, we just ignore it and read the unit from the search
493 * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
495 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
497 * load .d/*.conf dropins for device units
499 * allow implementation of InaccessibleDirectories=/ plus
500 ReadOnlyDirectories=... for whitelisting files for a service.
504 - GetAllProperties() on a non-existing object does not result in a failure currently
505 - port to sd-resolve for connecting to TCP dbus servers
506 - 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
507 - see if we can drop more message validation on the sending side
508 - add API to clone sd_bus_message objects
509 - longer term: priority inheritance
511 - NameLost/NameAcquired obsolete
514 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
517 - allow multiple signal handlers per signal?
518 - document chaining of signal handler for SIGCHLD and child handlers
519 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
520 - generate a failure of a default event loop is executed out-of-thread
521 - maybe add support for inotify events
523 * investigate endianness issues of UUID vs. GUID
525 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
526 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
528 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
530 * add a pam module that on password changes updates any LUKS slot where the password matches
532 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
535 - add 'set -e' to scripts in test/
536 - make stuff in test/ work with separate output dir
538 * seems that when we follow symlinks to units we prefer the symlink
539 destination path over /etc and /usr. We should not do that. Instead
540 /etc should always override /run+/usr and also any symlink
543 * when isolating, try to figure out a way how we implicitly can order
544 all units we stop before the isolating unit...
546 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
548 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
549 that the boot loader should be installed to the ESP. Define a way
550 how an installer can figure out whether a BLS compliant boot loader
553 * think about requeuing jobs when daemon-reload is issued? usecase:
554 the initrd issues a reload after fstab from the host is accessible
555 and we might want to requeue the mounts local-fs acquired through
558 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
560 * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
562 * shutdown logging: store to EFI var, and store to USB stick?
564 * merge unit_kill_common() and unit_kill_context()
566 * introduce ExecCondition= in services
569 - honor language efi variables for default language selection (if there are any?)
570 - honor timezone efi variables for default timezone selection (if there are any?)
571 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
573 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
575 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
577 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
580 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
581 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
582 - logind: wakelock/opportunistic suspend support
583 - Add pretty name for seats in logind
584 - logind: allow showing logout dialog from system?
585 - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
586 - session scopes/user unit: add RequiresMountsFor for the home directory of the user
587 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
588 - if pam_systemd is invoked by su from a process that is outside of a
589 any session we should probably just become a NOP, since that's
590 usually not a real user session but just some system code that just
592 - logind: make the Suspend()/Hibernate() bus calls wait for the for
593 the job to be completed. before returning, so that clients can wait
594 for "systemctl suspend" to finish to know when the suspending is
596 - logind: when the power button is pressed short, just popup a
597 logout dialog. If it is pressed for 1s, do the usual
598 shutdown. Inspiration are Macs here.
599 - expose "Locked" property on logind sesison objects
600 - given that logind now lets PID 1 do all nasty work, we can
601 probably reduce the capability set it retains substantially.
602 (we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
603 - expose orientation sensors and tablet mode through logind
604 - maybe allow configuration of the StopTimeout for session scopes
605 - rename session scope so that it includes the UID. THat way
606 the session scope can be arranged freely in slices and we don't have
607 make assumptions about their slice anymore.
608 - follow PropertiesChanged state more closely, to deal with quick logouts and
611 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
614 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
615 - import and delete pstore filesystem content at startup
616 - journald: also get thread ID from client, plus thread name
617 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
618 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
619 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
620 - declare the local journal protocol stable in the wiki interface chart
621 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
622 - journald: when dropping msgs due to ratelimit make sure to write
623 "dropped %u messages" not only when we are about to print the next
624 message that works, but alraedy after a short tiemout
625 - check if we can make journalctl by default use --follow mode inside of less if called without args?
626 - maybe add API to send pairs of iovecs via sd_journal_send
627 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
628 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
629 and !FOOBAR for events without FOOBAR.
630 - journal: store timestamp of journal_file_set_offline() int he header,
631 so it is possible to display when the file was last synced.
632 - 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.
633 - journal: find a way to allow dropping history early, based on priority, other rules
634 - journal: When used on NFS, check payload hashes
635 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
636 - refuse taking lower-case variable names in sd_journal_send() and friends.
637 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
638 - journal: deal nicely with byte-by-byte copied files, especially regards header
639 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
640 - Replace utmp, wtmp, btmp, and lastlog completely with journal
641 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
642 - when a kernel driver logs in a tight loop, we should ratelimit that too.
643 - journald: optionally, log debug messages to /run but everything else to /var
644 - journald: when we drop syslog messages because the syslog socket is
645 full, make sure to write how many messages are lost as first thing
646 to syslog when it works again.
647 - change systemd-journal-flush into a service that stays around during
648 boot, and causes the journal to be moved back to /run on shutdown,
649 so that we do not keep /var busy. This needs to happen synchronously,
650 hence doing this via signals is not going to work.
651 - optionally support running journald from the command line for testing purposes in external projects
652 - journald: allow per-priority and per-service retention times when rotating/vacuuming
653 - journald: make use of uid-range.h to managed uid ranges to split
655 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
656 - improve journalctl performance by loading journal files
657 lazily. Encode just enough information in the file name, so that we
658 do not have to open it to know that it is not interesting for us, for
659 the most common operations.
660 - journal-or-kmsg is currently broken? See reverted
661 commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
662 - man: document that corrupted journal files is nothing to act on
663 - rework journald sigbus stuff to use mutex
664 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
665 services that run under their own user ids, and use User= (but only
666 in a world where userns is ubiquitous since otherwise we cannot
667 invoke those daemons on the host AND in a container anymore). Also,
668 if LimitNPROC= is used without User= we should warn and refuse
670 - journalctl --verify: don't show files that are currently being
671 written to as FAIL, but instead show that their are being written to.
672 - add journalctl -H that talks via ssh to a remote peer and passes through
674 - add a version of --merge which also merges /var/log/journal/remote
675 - journalctl: -m should access container journals directly by enumerating
676 them via machined, and also watch containers coming and going.
677 Benefit: nspawn --ephemeral would start working nicely with the journal.
678 - assign MESSAGE_ID to log messages about failed services
680 * add a test if all entries in the catalog are properly formatted.
681 (Adding dashes in a catalog entry currently results in the catalog entry
682 being silently skipped. journalctl --update-catalog must warn about this,
683 and we should also have a unit test to check that all our message are OK.)
686 - document that deps in [Unit] sections ignore Alias= fields in
687 [Install] units of other units, unless those units are disabled
688 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
689 - document that service reload may be implemented as service reexec
690 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
691 - document systemd-journal-flush.service properly
692 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
693 - man: document the very specific env the shutdown drop-in tools live in
694 - man: add more examples to man pages
695 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
698 - add systemctl switch to dump transaction without executing it
699 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
700 - "systemctl disable" on a static unit prints no message and does
701 nothing. "systemctl enable" does nothing, and gives a bad message
702 about it. Should fix both to print nice actionable messages.
703 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
704 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
705 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
706 - systemctl: "Journal has been rotated since unit was started." message is misleading
707 - systemctl status output should include list of triggering units and their status
710 - "systemctl mask" should find all names by which a unit is accessible
711 (i.e. by scanning for symlinks to it) and link them all to /dev/null
714 - timer units should get the ability to trigger when:
715 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
717 - Modulate timer frequency based on battery state
719 * add libsystemd-password or so to query passwords during boot using the password agent logic
721 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
723 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
725 * make repeated alt-ctrl-del presses printing a dump
727 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
729 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
732 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
733 with seccomp. That should provide us with a useful log buffer that
734 systemd can log to during early boot, and disconnect container logs
735 from the kernel's logs.
736 - as soon as networkd has a bus interface, hook up --network-interface=,
737 --network-bridge= with networkd, to trigger netdev creation should an
739 - a nice way to boot up without machine id set, so that it is set at boot
740 automatically for supporting --ephemeral. Maybe hash the host machine id
741 together with the machine name to generate the machine id for the container
742 - fix logic always print a final newline on output.
743 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
744 - should optionally support receiving WATCHDOG=1 messages from its payload
746 - optionally automatically add FORWARD rules to iptables whenever nspawn is
747 running, remove them when shut down.
748 - maybe make copying of /etc/resolv.conf optional, and skip it if --read-only
752 - refuse mounting over a mount point
753 - automatically discover .roothash files in dissect, similarly to nspawn
756 - add an API so that libvirt-lxc can inform us about network interfaces being
757 removed or added to an existing machine
758 - "machinectl migrate" or similar to copy a container from or to a
759 difference host, via ssh
760 - introduce systemd-nspawn-ephemeral@.service, and hook it into
761 "machinectl start" with a new --ephemeral switch
762 - "machinectl status" should also show internal logs of the container in
764 - "machinectl list-images" should show os-release data, as well as
765 machine-info data (including deployment level)
766 - "machinectl history"
768 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
769 shell in it, and marks it read-only after use
772 - generate a nice warning if mkfs.btrfs is missing
775 - cryptsetup-generator: allow specification of passwords in crypttab itself
776 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
778 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
779 https://bugs.freedesktop.org/show_bug.cgi?id=54712
781 * create /sbin/init symlinks from the build system
783 * add a dependency on standard-conf.xml and other included files to man pages
785 * MountFlags=shared acts as MountFlags=slave right now.
787 * properly handle loop back mounts via fstab, especially regards to fsck/passno
789 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
794 - add trigger --subsystem-match=usb/usb_device device
795 - reimport udev db after MOVE events for devices without dev_t
797 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
799 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
802 - save coredump in Windows/Mozilla minidump format
803 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
805 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
807 * default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max
809 * be able to specify a forced restart of service A where service B depends on, in case B
810 needs to be auto-respawned?
813 - apply "x" on "D" too (see patch from William Douglas)
815 - instead of ignoring unknown fields, reject them.
816 - creating new directories/subvolumes/fifos/device nodes
817 should not follow symlinks. None of the other adjustment or creation
818 calls follow symlinks.
820 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
822 * verify that the AF_UNIX sockets of a service in the fs still exist
823 when we start a service in order to avoid confusion when a user
824 assumes starting a service is enough to make it accessible
826 * Make it possible to set the keymap independently from the font on
827 the kernel cmdline. Right now setting one resets also the other.
829 * and a dbus call to generate target from current state
831 * write blog stories about:
832 - hwdb: what belongs into it, lsusb
833 - enabling dbus services
834 - how to make changes to sysctl and sysfs attributes
836 - how to pass throw-away units to systemd, or dynamically change properties of existing units
837 - testing with Harald's awesome test kit
839 - how to develop against journal browsing APIs
840 - the journal HTTP iface
841 - non-cgroup resource management
842 - dynamic resource management with cgroups
843 - refreshed, longer missions statement
844 - calendar time events
845 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
846 - how to create your own target
847 - instantiated apache, dovecot and so on
848 - hooking a script into various stages of shutdown/rearly booot
850 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
852 * dot output for --test showing the 'initial transaction'
855 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
856 log both units as UNIT=, so that journalctl -u triggers on both.
857 - generate better errors when people try to set transient properties
858 that are not supported...
859 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
860 - maybe introduce WantsMountsFor=? Usecase:
861 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
862 - recreate systemd's D-Bus private socket file on SIGUSR2
863 - move PAM code into its own binary
864 - when we automatically restart a service, ensure we restart its rdeps, too.
865 - hide PAM options in fragment parser when compile time disabled
866 - Support --test based on current system state
867 - 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().
868 - after deserializing sockets in socket.c we should reapply sockopts and things
869 - drop PID 1 reloading, only do reexecing (difficult: Reload()
870 currently is properly synchronous, Reexec() is weird, because we
871 cannot delay the response properly until we are back, so instead of
872 being properly synchronous we just keep open the fd and close it
873 when done. That means clients do not get a successful method reply,
874 but much rather a disconnect on success.
875 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
876 - when a bus name of a service disappears from the bus make sure to queue further activation requests
879 - allow port=0 in .socket units
880 - maybe introduce ExecRestartPre=
881 - add ReloadSignal= for configuring a reload signal to use
882 - implement Register= switch in .socket units to enable registration
883 in Avahi, RPC and other socket registration services.
884 - allow Type=simple with PIDFile=
885 https://bugzilla.redhat.com/show_bug.cgi?id=723942
886 - allow writing multiple conditions in unit files on one line
887 - load-fragment: when loading a unit file via a chain of symlinks
888 verify that it is not masked via any of the names traversed.
889 - introduce Type=pid-file
890 - introduce mix of BindTo and Requisite
891 - add a concept of RemainAfterExit= to scope units
892 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
895 - Make sure ID_PATH is always exported and complete for
896 network devices where possible, so we can safely rely
898 - check MTUBytes parsing (expecting size_t but we are using unsigned)
901 - add support for more attribute types
902 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
905 - add more keys to [Route] and [Address] sections
906 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
907 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
908 - add reduced [Link] support to .network files
909 - add Scope= parsing option for [Network]
910 - properly handle routerless dhcp leases
911 - work with non-Ethernet devices
912 - add support for more bond options
913 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
914 - the DHCP lease data (such as NTP/DNS) is still made available when
915 a carrier is lost on a link. It should be removed instantly.
916 - expose in the API the following bits:
917 - option 15, domain name and/or option 119, search list
918 - option 12, host name and/or option 81, fqdn
919 - option 123, 144, geolocation
920 - option 252, configure http proxy (PAC/wpad)
921 - provide a way to define a per-network interface default metric value
922 for all routes to it. possibly a second default for DHCP routes.
923 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
924 support Name=foo*|bar*|baz ?
925 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
926 - allow DUID/IAID to be customized, see issue #394.
927 - whenever uplink info changes, make DHCP server send out FORCERENEW
929 * networkd-wait-online:
930 - make operstates to wait for configurable?
933 - figure out how much we can increase Maximum Message Size
936 - add functions to set previously stored IPv6 addresses on startup and get
937 them at shutdown; store them in client->ia_na
938 - write more test cases
939 - implement reconfigure support, see 5.3., 15.11. and 22.20.
940 - implement support for temporary adressess (IA_TA)
941 - implement dhcpv6 authentication
942 - investigate the usefulness of Confirm messages; i.e. are there any
943 situations where the link changes without any loss in carrier detection
945 - some servers don't do rapid commit without a filled in IA_NA, verify
952 - natively watch for dbus-*.service symlinks (PENDING)
953 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
955 * fix alsa mixer restore to not print error when no config is stored
957 * make cryptsetup lower --iter-time
959 * patch kernel for xattr support in /dev, /proc/, /sys?
961 * kernel: add device_type = "fb", "fbcon" to class "graphics"
963 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
965 * /usr/bin/service should actually show the new command line
967 * 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=
969 * fedora: F20: go timer units all the way, leave cron.daily for cron
971 * neither pkexec nor sudo initialize environ[] from the PAM environment?
973 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
975 * register catalog database signature as file magic
977 * zsh shell completion:
978 - <command> <verb> -<TAB> should complete options, but currently does not
979 - systemctl add-wants,add-requires
984 * look for close() vs. close_nointr() vs. close_nointr_nofail()
986 * check for strerror(r) instead of strerror(-r)
990 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
992 * use secure_getenv() instead of getenv() where appropriate
994 * link up selected blog stories from man pages and unit files Documentation= fields
