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
15 * When systemctl --host is used, underlying ssh connection can remain open.
16 bus_close does not kill children?
20 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
22 * wiki: update journal format documentation for lz4 additions
26 * code cleanup: retire FOREACH_WORD_QUOTED, port to extract_first_word() loops instead
28 * replace manual readdir() loops with FOREACH_DIRENT or FOREACH_DIRENT_ALL
30 * Get rid of the last strerror() invocations in favour of %m and strerror_r()
32 * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
36 * do something about "/control" subcgroups in the unified cgroup hierarchy
38 * when we detect that there are waiting jobs but no running jobs, do something
40 * push CPUAffinity also into the "cpuset" cgroup controller
42 * add a concept of RemainAfterExit= to scope units
44 * add a new command "systemctl revert" or so, that removes all dropin
45 snippets in /run and /etc, and all unit files with counterparts in
46 /usr, and thus undoes what "systemctl set-property" and "systemctl
47 edit" create. Maybe even add "systemctl revert -a" to do this for
50 * sd-event: maybe add support for inotify events
52 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
54 * nspawn should send out sd_notify("WATCHDOG=1") messages
56 * nspawn should optionally support receiving WATCHDOG=1 messages from its payload PID 1...
58 * consider throwing a warning if a service declares it wants to be "Before=" a .device unit.
60 * "systemctl edit" should know a mode to create a new unit file
62 * there's probably something wrong with having user mounts below /sys,
63 as we have for debugfs. for exmaple, src/core/mount.c handles mounts
64 prefixed with /sys generally special.
65 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
67 * Add PassEnvironment= setting to service units, to import select env vars from PID 1 into the service env block
69 * nspawn: fix logic always print a final newline on output.
70 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
72 * make nspawn's --network-veth switch more powerful:
73 http://lists.freedesktop.org/archives/systemd-devel/2015-June/033121.html
75 * man: document that unless you use StandardError=null the shell >/dev/stderr won't work in shell scripts in services
77 * "systemctl daemon-reload" should result in /etc/systemd/system.conf being reloaded by systemd
79 * install: include generator dirs in unit file search paths
81 * logind: follow PropertiesChanged state more closely, to deal with quick logouts and relogins
83 * invent a better systemd-run scheme for naming scopes, that works with remoting
85 * add journalctl -H that talks via ssh to a remote peer and passes through binary logs data
87 * change journalctl -M to acquire fd to journal directory via machined, and then operate on that via openat() instead of absolute paths
89 * add a version of --merge which also merges /var/log/journal/remote
91 * log accumulated resource usage after each service invocation
93 * nspawn: a nice way to boot up without machine id set, so that it is set at boot automatically for supporting --ephemeral. Maybe hash the host machine id together with the machine name to generate the machine id for the container
95 * logind: rename session scope so that it includes the UID. THat way
96 the session scope can be arranged freely in slices and we don't have
97 make assumptions about their slice anymore.
99 * journalctl: -m should access container journals directly by enumerating them via machined, and also watch containers coming and going. Benefit: nspawn --ephemeral would start working nicely with the journal.
101 * nspawn: don't copy /etc/resolv.conf from host into container unless we are in shared-network mode
103 * nspawn: optionally automatically add FORWARD rules to iptables whenever nspawn is running, remove them when shut down.
105 * importd: generate a nice warning if mkfs.btrfs is missing
107 * nspawn: add a logic for cleaning up read-only, hidden container images in /var/lib/machines that are not ancestors of any non-hidden containers
109 * nspawn: Improve error message when --bind= is used on a non-existing source directory
111 * nspawn: maybe make copying of /etc/resolv.conf optional, and skip it if --read-only is used
113 * man: document how update dkr images works with machinectl
114 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028630.html
116 * nspawn: as soon as networkd has a bus interface, hook up --network-interface=, --network-bridge= with networkd, to trigger netdev creation should an interface be missing
118 * rework C11 utf8.[ch] to use char32_t instead of uint32_t when referring
119 to unicode chars, to make things more expressive.
121 * "machinectl migrate" or similar to copy a container from or to a
122 difference host, via ssh
124 * tmpfiles: creating new directories/subvolumes/fifos/device nodes
125 should not follow symlinks. None of the other adjustment or creation
126 calls follow symlinks.
128 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
130 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
132 * mounting and unmounting mount points manually with different source
133 devices will result in collected collected on all devices used.
134 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030225.html
136 * add a job mode that will fail if a transaction would mean stopping
137 running units. Use this in timedated to manage the NTP service
139 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
141 * Maybe add support for the equivalent of "ethtool advertise" to .link files?
142 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
144 * .timer units should optionally support CLOCK_BOOTTIME in addition to CLOCK_MONOTONIC
146 * When logging about multiple units (stopping BoundTo units, conflicts, etc.),
147 log both units as UNIT=, so that journalctl -u triggers on both.
149 * to allow "linking" of nspawn containers, extend --network-bridge= so
150 that it can dynamically create bridge interfaces that are refcounted
151 by the containers on them. For each group of containers to link together
153 * journalctl --verify: don't show files that are currently being
154 written to as FAIL, but instead show that their are being written
157 * assign MESSAGE_ID to log messages about failed services
159 * coredump: make the handler check /proc/$PID/rlimits for RLIMIT_CORE,
160 and supress coredump if turned off. Then change RLIMIT_CORE to
161 infinity by default for all services. This then allows per-service
162 control of coredumping.
164 * generate better errors when people try to set transient properties
165 that are not supported...
166 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
168 * maybe introduce WantsMountsFor=? Usecase:
169 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
171 * The udev blkid built-in should expose a property that reflects
172 whether media was sensed in USB CF/SD card readers. This should then
173 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
174 picked up by systemd unless they contain a medium. This would mirror
175 the behaviour we already have for CD drives.
177 * nspawn: emulate /dev/kmsg using CUSE and turn off the syslog syscall
178 with seccomp. That should provide us with a useful log buffer that
179 systemd can log to during early boot, and disconnect container logs
180 from the kernel's logs.
182 * networkd/udev: implement SR_IOV configuration in .link files:
183 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
185 * Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
186 services that run under their own user ids, and use User= (but only
187 in a world where userns is ubiquitous since otherwise we cannot
188 invoke those daemons on the host AND in a container anymore). Also,
189 if LimitNPROC= is used without User= we should warn and refuse
192 * logind: maybe allow configuration of the StopTimeout for session scopes
194 * Set NoNewPrivileges= on all of our own services, where that makes sense
196 * Rework systemctl's GetAll property parsing to use the generic bus_map_all_properties() API
198 * rework journald sigbus stuff to use mutex
200 * import-dkr: support tarsum checksum verification, if it becomes reality one day...
202 * import-dkr: convert json bits to nspawn configuration
204 * core/cgroup: support net_cls modules, and support automatically allocating class ids, then add support for making firewall changes depending on it, to implement a per-service firewall
206 * introduce systemd-nspawn-ephemeral@.service, and hook it into "machinectl start" with a new --ephemeral switch
208 * "machinectl status" should also show internal logs of the container in question
210 * "machinectl list-images" should show os-release data, as well as machine-info data (including deployment level)
212 * Port various tools to make use of verbs.[ch], where applicable
214 * "machinectl history"
218 * "machinectl commit" that takes a writable snapshot of a tree, invokes a shell in it, and marks it read-only after use
220 * systemd-nspawn -x should support ephemeral instances of gpt images
222 * hostnamectl: show root image uuid
224 * sysfs set api in libudev is not const
226 * Find a solution for SMACK capabilities stuff:
227 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
229 * "systemctl preset-all" should probably order the unit files it
230 operates on lexicographically before starting to work, in order to
231 ensure deterministic behaviour if two unit files conflict (like DMs
234 * resolved should optionally register additional per-interface LLMNR
235 names, so that for the container case we can establish the same name
236 (maybe "host") for referencing the server, everywhere.
238 * systemd-journal-upload (or a new, related tool): allow pushing out
239 journal messages onto the network in BSD syslog protocol,
240 continuously. Default to some link-local IP mcast group, to make this
241 useful as a one-stop debugging tool.
243 * synchronize console access with BSD locks:
244 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
246 * as soon as we have kdbus, and sender timestamps, revisit coalescing multiple parallel daemon reloads:
247 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
249 * the install state probably shouldn't get confused by generated units, think dbus1/kdbus compat!
251 * in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
253 * figure out when we can use the coarse timers
255 * add "systemctl start -v foobar.service" that shows logs of a service
256 while the start command runs. This is non-trivial to do without
257 races though, since we should flush out all journal messages before
258 returning from the "systemctl stop".
260 * 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
262 * timesyncd + resolved: add ugly bus calls to set NTP and DNS servers per-interface, for usage by NM
264 * add infrastructure to allocate dynamic/transient users and UID ranges, for use in user-namespaced containers, per-seat gdm login screens and gdm guest sessions
266 * machined: add an API so that libvirt-lxc can inform us about network interfaces being removed or added to an existing machine
268 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
270 * introduce systemd-timesync-wait.service or so to sync on an NTP fix?
272 * systemd --user should issue sd_notify() upon reaching basic.target, not on becoming idle
274 * consider showing the unit names during boot up in the status output, not just the unit descriptions
276 * dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
278 * maybe allow timer units with an empty Units= setting, so that they
279 can be used for resuming the system but nothing else.
281 * what to do about udev db binary stability for apps? (raw access is not an option)
283 * maybe provide an API to allow migration of foreign PIDs into existing scopes.
285 * maybe support a new very "soft" reboot mode, that simply kills all processes, disassembles everything, flushes /run and sysvipc, and then reexecs systemd again
287 * man: document that corrupted journal files is nothing to act on
289 * man: maybe use the word "inspect" rather than "introspect"?
291 * "machinectl list" should probably show columns for OS version and IP addresses
293 * systemctl: if some operation fails, show log output?
296 - allow creation of units from scratch
297 - use equvalent of cat() to insert existing config as a comment, prepended with #.
298 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
300 * refcounting in sd-resolve is borked
302 * exponential backoff in timesyncd and resolved when we cannot reach a server
304 * extract_many_words() should probably be used by a lot of code that
305 currently uses FOREACH_WORD and friends. For example, most conf
306 parsing callbacks should use it.
308 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
310 * systemd.show_status= should probably have a mode where only failed
313 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
314 (throughout the codebase, not only PID1)
317 - add LLDP client side support
318 - the DHCP lease data (such as NTP/DNS) is still made available when
319 a carrier is lost on a link. It should be removed instantly.
320 - expose in the API the following bits:
321 - option 15, domain name and/or option 119, search list
322 - option 12, host name and/or option 81, fqdn
323 - option 123, 144, geolocation
324 - option 252, configure http proxy (PAC/wpad)
325 - provide a way to define a per-network interface default metric value
326 for all routes to it. possibly a second default for DHCP routes.
327 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
328 support Name=foo*|bar*|baz ?
329 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
330 - allow DUID/IAID to be customized, see issue #394.
331 - support configuration option for TSO (tcp segmentation offload)
332 - networkd: whenever uplink info changes, make DHCP server send out FORCERENEW
335 - put networkd events and rtnl events at a higher priority, so that
336 we always process them before we process client requests
338 - add display of private key types (http://tools.ietf.org/html/rfc4034#appendix-A.1.1)?
343 - DNS-SD service registration from socket units
345 - dname: Not necessary for plain DNS as synthesized cname is handed out instead if we do not
346 announce dname support. However, for DNSSEC it is necessary as the synthesized cname
350 * Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
352 * Add a new verb "systemctl top"
354 * add new gpt type for btrfs volumes
356 * support empty /etc boots nicely:
357 - nspawn/gpt-generator: introduce new gpt partition type for /usr
358 - fstab-generator: support systemd.volatile=yes|no|state on the kernel cmdline, too, similar to nspawn's --volatile=
360 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
362 * timer units: actually add extra delays to timer units with high AccuracySec values, don't start them already when we are awake...
364 * a way for container managers to turn off getty starting via $container_headless= or so...
366 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
368 * mount_cgroup_controllers(): symlinks need to get the label applied
370 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
371 they run added to the initial transaction and thus confuse Type=idle.
373 * Run most system services with cgroupfs read-only and procfs with a more secure mode (doesn't work, since the hidepid= option is per-pid-namespace, not per-mount)
375 * sd-event: generate a failure of a default event loop is executed out-of-thread
377 * add bus api to query unit file's X fields.
379 * consider adding RuntimeDirectoryUser= + RuntimeDirectoryGroup=
381 * sd-event: define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
383 * gpt-auto-generator:
384 - Support LUKS for root devices
385 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
386 - Make /home automount rather than mount?
388 * add generator that pulls in systemd-network from containers when
389 CAP_NET_ADMIN is set, more than the loopback device is defined, even
390 when it is otherwise off
392 * MessageQueueMessageSize= and RLimitFSIZE= (and suchlike) should use parse_iec_size().
394 * "busctl status" works only as root on dbus1, since we cannot read
397 * implement Distribute= in socket units to allow running multiple
398 service instances processing the listening socket, and open this up
401 * socket units: support creating sockets in different namespace,
402 opening it up for JoinsNamespaceOf=. This would require to fork off
403 a tiny process that joins the namespace and creates/binds the socket
404 and passes this back to PID1 via SCM_RIGHTS. This also could be used
405 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
407 * New service property: maximum CPU and wallclock runtime for a service
409 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
410 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
411 should SIGSTOP all unit processes in a loop until all processes of
412 it are fully stopped. This can later be used for app management by
413 desktop UIs such as gnome-shell to freeze apps that are not visible
414 on screen, not unlike how job control works on the shell
417 - implement per-slice CPUFairScheduling=1 switch
418 - handle jointly mounted controllers correctly
419 - introduce high-level settings for RT budget, swappiness
420 - how to reset dynamically changed unit cgroup attributes sanely?
421 - when reloading configuration, apply new cgroup configuration
422 - when recursively showing the cgroup hierarchy, optionally also show
423 the hierarchies of child processes
426 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
427 - ensure scope units may be started only a single time
429 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
431 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
433 * machined, localed: when we try to kill an empty cgroup, generate an ESRCH error over the bus
435 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
437 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
439 * unify dispatch table in systemctl_main() and friends
441 * 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
443 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
445 * If we try to find a unit via a dangling symlink, generate a clean
446 error. Currently, we just ignore it and read the unit from the search
449 * refuse boot if /etc/os-release is missing or /etc/machine-id cannot be set up
451 * btrfs raid assembly: some .device jobs stay stuck in the queue
453 * make sure gdm does not use multi-user-x but the new default X configuration file, and then remove multi-user-x from systemd
455 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
457 * load .d/*.conf dropins for device units
459 * allow implementation of InaccessibleDirectories=/ plus
460 ReadOnlyDirectories=... for whitelisting files for a service.
464 - GetAllProperties() on a non-existing object does not result in a failure currently
465 - kdbus: process fd=-1 for incoming msgs
466 - port to sd-resolve for connecting to TCP dbus servers
467 - kdbus: maybe add controlling tty metadata fields
468 - 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
469 - when kdbus does not take our message without memfds, try again with memfds
470 - see if we can drop more message validation on the sending side
471 - add API to clone sd_bus_message objects
472 - make AddMatch calls on dbus1 transports async?
473 - kdbus: matches against source or destination pids for an "strace -p"-like feel. Problem: The PID info needs to be available in userspace too...
474 - longer term: priority inheritance
477 - NameLost/NameAcquired obsolete
480 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
481 - test bloom filter generation indexes
482 - bus-proxy: when passing messages from kdbus, make sure we properly
483 handle the case where a large number of fds is appended that we
484 cannot pass into sendmsg() of the AF_UNIX sokcet (which only accepts
486 - kdbus: introduce a concept of "send-only" connections
487 - kdbus: add counter for refused unicast messages that is passed out via the RECV ioctl. SImilar to the counter for dropped multicast messages we already have.
490 - allow multiple signal handlers per signal?
491 - document chaining of signal handler for SIGCHLD and child handlers
493 * in the final killing spree, detect processes from the root directory, and
494 complain loudly if they have argv[0][0] == '@' set.
495 https://bugzilla.redhat.com/show_bug.cgi?id=961044
497 * investigate endianness issues of UUID vs. GUID
499 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
500 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
502 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
504 * add a pam module that on password changes updates any LUKS slot where the password matches
506 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
508 * cgtop: make cgtop useful in a container
511 - add 'set -e' to scripts in test/
512 - make stuff in test/ work with separate output dir
514 * seems that when we follow symlinks to units we prefer the symlink
515 destination path over /etc and /usr. We should not do that. Instead
516 /etc should always override /run+/usr and also any symlink
519 * when isolating, try to figure out a way how we implicitly can order
520 all units we stop before the isolating unit...
522 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
524 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
525 that the boot loader should be installed to the ESP. Define a way
526 how an installer can figure out whether a BLS compliant boot loader
529 * think about requeuing jobs when daemon-reload is issued? usecase:
530 the initrd issues a reload after fstab from the host is accessible
531 and we might want to requeue the mounts local-fs acquired through
534 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
536 * journal-or-kmsg is currently broken? See reverted commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
538 * remove any syslog support from log.c -- we probably cannot do this before split-off udev is gone for good
540 * shutdown logging: store to EFI var, and store to USB stick?
542 * write UI tool that pops up emergency messages from the journal as notification
544 * think about window-manager-run-as-user-service problem: exit 0 → activate shutdown.target; exit != 0 → restart service
546 * merge unit_kill_common() and unit_kill_context()
548 * introduce ExecCondition= in services
551 - honor language efi variables for default language selection (if there are any?)
552 - honor timezone efi variables for default timezone selection (if there are any?)
553 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
555 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
557 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
559 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
562 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
563 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
564 - logind: wakelock/opportunistic suspend support
565 - Add pretty name for seats in logind
566 - logind: allow showing logout dialog from system?
567 - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
568 - session scopes/user unit: add RequiresMountsFor for the home directory of the user
569 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
570 - if pam_systemd is invoked by su from a process that is outside of a
571 any session we should probably just become a NOP, since that's
572 usually not a real user session but just some system code that just
574 - logind: make the Suspend()/Hibernate() bus calls wait for the for
575 the job to be completed. before returning, so that clients can wait
576 for "systemctl suspend" to finish to know when the suspending is
578 - logind: when the power button is pressed short, just popup a
579 logout dialog. If it is pressed for 1s, do the usual
580 shutdown. Inspiration are Macs here.
581 - expose "Locked" property on logind sesison objects
582 - given that logind now lets PID 1 do all nasty work, we can
583 probably reduce the capability set it retains substantially.
584 (we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
585 - expose orientation sensors and tablet mode through logind
587 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
589 * service: watchdog logic: for testing purposes allow ping, but do not require pong
592 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
593 - import and delete pstore filesystem content at startup
594 - journald: also get thread ID from client, plus thread name
595 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
596 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
597 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
598 - declare the local journal protocol stable in the wiki interface chart
599 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
600 - journald: when dropping msgs due to ratelimit make sure to write
601 "dropped %u messages" not only when we are about to print the next
602 message that works, but alraedy after a short tiemout
603 - check if we can make journalctl by default use --follow mode inside of less if called without args?
604 - maybe add API to send pairs of iovecs via sd_journal_send
605 - journal: when writing journal auto-rotate if time jumps backwards
606 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
607 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
608 and !FOOBAR for events without FOOBAR.
609 - journal: store timestamp of journal_file_set_offline() int he header,
610 so it is possible to display when the file was last synced.
611 - 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.
612 - journal: find a way to allow dropping history early, based on priority, other rules
613 - journal: When used on NFS, check payload hashes
614 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
615 - refuse taking lower-case variable names in sd_journal_send() and friends.
616 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
617 - journal: deal nicely with byte-by-byte copied files, especially regards header
618 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
619 - Replace utmp, wtmp, btmp, and lastlog completely with journal
620 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
621 - when a kernel driver logs in a tight loop, we should ratelimit that too.
622 - journald: optionally, log debug messages to /run but everything else to /var
623 - journald: when we drop syslog messages because the syslog socket is
624 full, make sure to write how many messages are lost as first thing
625 to syslog when it works again.
626 - journald: make sure ratelimit is actually really per-service with the new cgroup changes
627 - change systemd-journal-flush into a service that stays around during
628 boot, and causes the journal to be moved back to /run on shutdown,
629 so that we do not keep /var busy. This needs to happen synchronously,
630 hence doing this via signals is not going to work.
631 - optionally support running journald from the command line for testing purposes in external projects
632 - journald: allow per-priority and per-service retention times when rotating/vacuuming
633 - journald: make use of uid-range.h to managed uid ranges to split
635 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
636 - improve journalctl performance by loading journal files
637 lazily. Encode just enough information in the file name, so that we
638 do not have to open it to know that it is not interesting for us, for
639 the most common operations.
642 - document that deps in [Unit] sections ignore Alias= fields in
643 [Install] units of other units, unless those units are disabled
644 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
645 - document the exit codes when services fail before they are exec()ed
646 - document that service reload may be implemented as service reexec
647 - document in wiki how to map ical recurrence events to systemd timer unit calendar specifications
648 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
649 - document systemd-journal-flush.service properly
650 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
651 - man: document the very specific env the shutdown drop-in tools live in
652 - man: add more examples to man pages
653 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
656 - systemctl list-jobs - show dependencies
657 - add systemctl switch to dump transaction without executing it
658 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
659 - "systemctl disable" on a static unit prints no message and does
660 nothing. "systemctl enable" does nothing, and gives a bad message
661 about it. Should fix both to print nice actionable messages.
662 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
663 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
664 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
665 - systemctl: "Journal has been rotated since unit was started." message is misleading
666 - support "systemctl stop foobar@.service" to stop all units matching a certain template
667 - Something is wrong with symlink handling of "autovt@.service" in "systemctl list-unit-files"
668 - better error message if you run systemctl without systemd running
669 - systemctl status output should should include list of triggering units and their status
672 - "systemctl mask" should find all names by which a unit is accessible
673 (i.e. by scanning for symlinks to it) and link them all to /dev/null
674 - systemctl list-unit-files should list generated files (and probably with a new state "generated" for them, or so)
677 - timer units should get the ability to trigger when:
678 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
680 - Support 2012-02~4 as syntax for specifying the fourth to last day of the month.
681 - calendarspec: support value ranges with ".." notation. Example: 2013-4..8-1
682 - when parsing calendar timestamps support the UTC timezone (even if we will not support arbitrary timezone specs, support UTC itself certainly makes sense), also support syntaxes such as +0200
683 - Modulate timer frequency based on battery state
685 * add libsystemd-password or so to query passwords during boot using the password agent logic
687 * 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().
689 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
691 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
693 * make repeated alt-ctrl-del presses printing a dump, or even force a reboot without
694 waiting for the timeout
696 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
698 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
701 - refuses to boot containers without /etc/machine-id (OK?), and with empty /etc/machine-id (not OK).
704 - cryptsetup-generator: allow specification of passwords in crypttab itself
705 - move cryptsetup key caching into kernel keyctl?
706 https://bugs.freedesktop.org/show_bug.cgi?id=54982
707 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
709 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
710 https://bugs.freedesktop.org/show_bug.cgi?id=54712
712 * after deserializing sockets in socket.c we should reapply sockopts and things
714 * make timer units go away after they elapsed
716 * move PID 1 segfaults to /var/lib/systemd/coredump?
718 * create /sbin/init symlinks from the build system
720 * allow writing multiple conditions in unit files on one line
722 * MountFlags=shared acts as MountFlags=slave right now.
724 * drop PID 1 reloading, only do reexecing (difficult: Reload()
725 currently is properly synchronous, Reexec() is weird, because we
726 cannot delay the response properly until we are back, so instead of
727 being properly synchronous we just keep open the fd and close it
728 when done. That means clients do not get a successful method reply,
729 but much rather a disconnect on success.
731 * properly handle loop back mounts via fstab, especially regards to fsck/passno
733 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
735 * rename "userspace" to "core-os"
737 * load-fragment: when loading a unit file via a chain of symlinks
738 verify that it is not masked via any of the names traversed.
740 * introduce Type=pid-file
742 * change Requires=basic.target to RequisiteOverride=basic.target
744 * when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
746 * ExecOnFailure=/usr/bin/foo
751 - add trigger --subsystem-match=usb/usb_device device
752 - reimport udev db after MOVE events for devices without dev_t
754 * when a service has the same env var set twice we actually store it twice and return that in systemctl show -p... We should only show the last setting
756 * introduce mix of BindTo and Requisite
758 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
760 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
762 * default unix qlen is too small (10). bump sysctl? add sockopt?
764 * save coredump in Windows/Mozilla minidump format
766 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
768 * default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max
770 * be able to specify a forced restart of service A where service B depends on, in case B
771 needs to be auto-respawned?
773 * when a bus name of a service disappears from the bus make sure to queue further activation requests
776 - apply "x" on "D" too (see patch from William Douglas)
778 - instead of ignoring unknown fields, reject them.
780 * for services: do not set $HOME in services unless requested
782 * hide PAM options in fragment parser when compile time disabled
784 * when we automatically restart a service, ensure we restart its rdeps, too.
786 * allow Type=simple with PIDFile=
787 https://bugzilla.redhat.com/show_bug.cgi?id=723942
789 * move PAM code into its own binary
791 * implement Register= switch in .socket units to enable registration
792 in Avahi, RPC and other socket registration services.
794 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
796 * add ReloadSignal= for configuring a reload signal to use
798 * verify that the AF_UNIX sockets of a service in the fs still exist
799 when we start a service in order to avoid confusion when a user
800 assumes starting a service is enough to make it accessible
802 * Make it possible to set the keymap independently from the font on
803 the kernel cmdline. Right now setting one resets also the other.
805 * and a dbus call to generate target from current state
807 * GC unreferenced jobs (such as .device jobs)
809 * write blog stories about:
810 - hwdb: what belongs into it, lsusb

827 - hooking a script into various stages of shutdown/rearly booot
829 * allow port=0 in .socket units
831 * recreate systemd's D-Bus private socket file on SIGUSR2
833 * Support --test based on current system state
835 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
837 * maybe introduce ExecRestartPre=
839 * dot output for --test showing the 'initial transaction'
841 * fingerprint.target, wireless.target, gps.target, netdevice.target
844 - figure out a simple way to wait for journal events in a way that
846 - add documentation to systemd.daemon
849 - plot per-process IO utilization
850 - group processes based on service association (cgroups)
851 - document initcall_debug
852 - kernel cmdline "bootchart" option for simplicity?
855 - Make sure ID_PATH is always exported and complete for
856 network devices where possible, so we can safely rely
858 - check MTUBytes parsing (expecting size_t but we are using unsigned)
861 - add support for more attribute types
862 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
865 - add more keys to [Route] and [Address] sections
866 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
867 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
868 - add reduced [Link] support to .network files
869 - add Scope= parsing option for [Network]
870 - properly handle routerless dhcp leases
871 - add more attribute support for SIT tunnel

879 - figure out how much we can increase Maximum Message Size
880 - support RFC4702 (pass FQDN)
883 - add functions to set previously stored IPv6 addresses on startup and get
884 them at shutdown; store them in client->ia_na
885 - write more test cases
886 - implement reconfigure support, see 5.3., 15.11. and 22.20.
887 - implement support for temporary adressess (IA_TA)
888 - implement dhcpv6 authentication
889 - investigate the usefulness of Confirm messages; i.e. are there any
890 situations where the link changes without any loss in carrier detection
892 - some servers don't do rapid commit without a filled in IA_NA, verify
898 - natively watch for dbus-*.service symlinks (PENDING)
899 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
901 * fix alsa mixer restore to not print error when no config is stored
903 * make cryptsetup lower --iter-time
905 * patch kernel for xattr support in /dev, /proc/, /sys?
907 * kernel: add device_type = "fb", "fbcon" to class "graphics"
909 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
911 * dbus upstream still refers to dbus.target and should not
913 * dbus: in fedora, make /var/lib/dbus/machine-id a symlink to /etc/machine-id
915 * add "# export SYSTEMD_PAGER=" to bash login
917 * /usr/bin/service should actually show the new command line
919 * 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=
921 * fedora: F20: go timer units all the way, leave cron.daily for cron
923 * neither pkexec nor sudo initialize environ[] from the PAM environment?
925 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
927 * register catalog database signature as file magic
929 * zsh shell completion:
930 - <command> <verb> -<TAB> should complete options, but currently does not
931 - systemctl add-wants,add-requires
936 * look for close() vs. close_nointr() vs. close_nointr_nofail()
938 * check for strerror(r) instead of strerror(-r)
940 * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
944 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
946 * use secure_getenv() instead of getenv() where appropriate
948 * link up selected blog stories from man pages and unit files Documentation= fields
950 Scheduled for removal or fixing:
952 * xxxOverridable dependencies (probably: fix)
