3 * enabling an instance unit creates a pointless link, and
4 the unit will be started with getty@getty.service:
5 $ systemctl enable getty@.service
6 ln -s '/usr/lib/systemd/system/getty@.service' '/etc/systemd/system/getty.target.wants/getty@.service'
8 * check systemd-tmpfiles for selinux context hookup for mknod(), symlink() and similar
10 * swap units that are activated by one name but shown in the kernel under another are semi-broken
12 * Dangling symlinks of .automount unit files in .wants/ directories, set up
13 automount points even when the original .automount file did not exist
14 anymore. Only the .mount unit was still around.
16 * make polkit checks async
18 * properly handle .mount unit state tracking when two mount points are stacked one on top of another on the exact same mount point.
20 * When we detect invalid UTF-8, we cannot use it in an error message:
21 log...("Path is not UTF-8 clean, ignoring assignment: %s", rvalue);
23 * shorten the message to sane length:
25 Cannot add dependency job for unit display-manager.service, ignoring: Unit display-manager.service failed to load: No such file or directory. See system logs and 'systemctl status display-manager.service' for details.
29 * external: ps should gain colums for slice and machine
32 - localectl: support new converted x11→console keymaps
34 * when installing fedora with yum --installroot /var/run is a directory, not a symlink
35 https://bugzilla.redhat.com/show_bug.cgi?id=975864
37 CGroup Rework Completion:
39 * introduce "mainpid" for scopes (or maybe not?)
41 * implement system-wide DefaultCPUAccounting=1 switch (and similar for blockio, memory?)
43 * implement per-slice CPUFairScheduling=1 switch
45 * handle jointly mounted controllers correctly
47 * introduce high-level settings for RT budget, swappiness
51 * saproxy: Support multiple inherited sockets mapped using different proxies
53 * saproxy: Use a nonblocking alternative to getaddrinfo
55 * saproxy: Until we can start daemons directly, find a less ugly, less racy alternative than shell scripts for the second man page example.
57 * saproxy: Support starting daemons directly without requiring a shell script; update man pages
59 * "systemctl cat" or "systemctl view" command or or so, that cats the backing unit file of a service, plus its drop-ins and shows them in a pager
61 * 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
63 * Add a new Distribute=$NUMBER key to socket units that makes use of SO_REUSEPORT to distribute network traffic on $NUMBER instances
65 * tmpfiles: when applying ownership to /run/log/journal, also do this for the journal fails contained in it
67 * we probably should replace the left-over uses of strv_append() and replace them by strv_push() or strv_extend()
69 * move config_parse_path_strv() out of conf-parser.c
71 * libdsystemd-bus should expose utf8 validation calls
73 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
75 * If we try to find a unit via a dangling symlink, generate a clean
76 error. Currently, we just ignore it and read the unit from the search
79 * When a Type=forking service fails and needed another service, that
80 service is not cleaned up again when it has StopWhenUnneeded=yes
81 http://lists.freedesktop.org/archives/systemd-devel/2013-July/012141.html
83 * refuse boot if /etc/os-release is missing or /etc/machine-id cannot be set up
85 * ensure scope units may be started only a single time
87 * better error message if you run systemctl without systemd running
89 * systemctl status output should should include list of triggering units and their status
91 * for transient units, instead of writing out drop-ins for all properties consider serializing them in the normal serialization stream
93 * logind: when logging out, remove user-owned sysv and posix IPC objects
95 * session scopes/user unit: add RequiresMountsFor for the home directory of the user
97 * add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
99 * journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
101 * given that logind/machined now let PID 1 do all nasty work, we can
102 probably reduce the capability set they retain substantially.
104 * btrfs raid assembly: some .device jobs stay stuck in the queue
106 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
108 * Fedora: post FPC ticket to move add %tmpfiles_create to the packaging guidelines
110 * make sure gdm doesn't use multi-user-x but the new default X configuration file, and then remove multi-user-x from systemd
112 * when parsing calendar timestamps support the UTC timezone (even if we won't support arbitrary timezone specs, support UTC itself certainly makes sense), also support syntaxes such as +0200
114 * when a kernel driver logs in a tight loop, we should ratelimit that too.
116 * "systemctl disable" of a unit instance removes all symlinks, but should
117 only remove the instance symlink (systemctl disable of a template
118 unit however should remove them all).
120 * journald: optionally, log debug messages to /run but everything else to /var
122 * systemctl list-unit-files should list generated files (and probably with a new state "generated" for them, or so)
124 * journald: when we drop syslog messages because the syslog socket is
125 full, make sure to write how many messages are lost as first thing
126 to syslog when it works again.
128 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
130 * load .d/*.conf dropins for device units
132 * add a fixed dbus path for "my own unit", "my own session", ... to PID1, logind, ...
134 * service_coldplug() appears to reinstall the wrong stop timeout watch.
136 * transient units: allow creating auxiliary units with the same call
138 * how to reset dynamically changed attributes sanely?
140 * when reloading configuration, apply new cgroup configuration
142 * journald: make sure ratelimit is actually really per-service with the new cgroup changes
144 * gparted needs to disable auto-activation of mount units somehow, or
145 maybe we should stop doing auto-activation of this after boot
146 entirely. https://bugzilla.gnome.org/show_bug.cgi?id=701676
147 Maybe take a BSD lock at the disk device node and teach udev to
148 check for that and suppress event handling.
150 * when recursively showing the cgroup hierarchy, optionally also show
151 the hierarchies of child processes
153 * document logic of auto/noauto and fail/nofail in fstab in systemd.mount or systemd-fstab-generator man page
155 * we should properly escape ssh hostnames we add into dbus server strings
157 * something pulls in pcre as shared object dependency into our daemons such as hostnamed.
159 * document systemd-journal-flush.service properly
161 * change systemd-journal-flush into a service that stays around during
162 boot, and causes the journal to be moved back to /run on shutdown,
163 so that we don't keep /var busy. This needs to happen synchronously,
164 hence doing this via signals is not going to work.
166 * allow implementation of InaccessibleDirectories=/ plus
167 ReadOnlyDirectories=... for whitelisting files for a service.
170 - default policy (allow uid == 0 and our own uid)
171 - enforce alignment of pointers passed in
172 - when kdbus doesn't take our message without memfds, try again with memfds
173 - implement translator service
174 - port systemd to new library
175 - implement busname unit type in systemd
177 - merge busctl into systemctl or so?
178 - synthesize sd_bus_message objects from kernel messages
179 - properly implement name registry ioctls for kdbus
180 - implement monitor logic
183 * priority inheritance
185 * in the final killing spree, detect processes from the root directory, and
186 complain loudly if they have argv[0][0] == '@' set.
187 https://bugzilla.redhat.com/show_bug.cgi?id=961044
189 * add an option to nspawn that uses seccomp to make socket(AF_NETLINK,
190 SOCK_RAW, NETLINK_AUDIT) fail the the appropriate error code that
191 makes the audit userspace to think auditing is not available in the
194 * Introduce a way how we can kill the main process of a service with KillSignal, but all processes with SIGKILL later on
195 https://bugzilla.redhat.com/show_bug.cgi?id=952634
197 * maybe add a warning to the unit file parses where the access mode of unit files is nonsensical.
199 * investigate endianness issues of UUID vs. GUID
201 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
202 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
204 * if pam_systemd is invoked by su from a process that is outside of a
205 any session we should probably just become a NOP, since that's
206 usually not a real user session but just some system code that just
209 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
211 * add a pam module that on password changes updates any LUKS slot where the password matches
213 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
215 * timedatctl, localectl: possibly make some commands work without the daemon, for chroot situations...
217 * logind: add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
219 * cgtop: make cgtop useful in a container
222 - add 'set -e' to scripts in test/
223 - make stuff in test/ work with separate output dir
224 - remove all the duplicated code in test/
226 * systemctl delete x.snapshot leaves no trace in logs (at least at default level).
228 * make the coredump collector tool move itself into the user's cgroup
229 so that the coredump is properly written to the user's own journal
232 * seems that when we follow symlinks to units we prefer the symlink
233 destination path over /etc and /usr. We shouldn't do that. Instead
234 /etc should always override /run+/usr and also any symlink
237 * when isolating, try to figure out a way how we implicitly can order
238 all units we stop before the isolating unit...
240 * add ConditionArchitecture= or so
242 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
244 * Support SO_REUSEPORT with socket activation:
245 - Let systemd maintain a pool of servers.
246 - Use for seamless upgrades, by running the new server before stopping the
249 * after all byte-wise realloc() is slow, even on glibc, so i guess we
250 need manual exponential loops after all
252 * BootLoaderSpec: drop allowing ext234 for $BOOT. Clarify that the
253 kernel has to be in $BOOT. Clarify that the boot loader should be
254 installed to the ESP. Define a way how an installer can figure out
255 whether a BLS compliant boot loader is installed.
257 * man: remove .include documentation, and instead push people to use .d/*.conf
259 * think about requeuing jobs when daemon-reload is issued? usecase:
260 the initrd issues a reload after fstab from the host is accessible
261 and we might want to requeue the mounts local-fs acquired through
264 * rework specifier logic so that we can distinguish OOM errors from other errors
266 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
268 * journal-or-kmsg is currently broken? See reverted commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
270 * remove any syslog support from log.c -- we probably can't do this before split-off udev is gone for good
272 * documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
274 * add a tool that lists active timer units plus their next elapse and the time the units ran last
276 * man: document the very specific env the shutdown drop-in tools live in
278 * shutdown logging: store to EFI var, and store to USB stick?
280 * man: extend runlevel(8) to mention that runlevels suck, and are dead. Maybe add runlevel(7) with a note about that too
282 * systemctl: maybe add "systemctl add-wants" or so...
284 * man: add more examples to man pages
286 * man: maybe sort directives in man pages, and take sections from --help and apply them to man too
288 * write UI tool that pops up emergency messages from the journal as notification
290 * think about window-manager-run-as-user-service problem: exit 0 → activate shutdown.target; exit != 0 → restart service
292 * msgcatalog determine default language of entries from the catalog
293 file name. i.e. foobar.de_DE.catalog would set the default entry
294 name for the entries to de_DE if they aren't explicitly suffixed
297 * use "log level" rather than "log priority" everywhere
299 * timedate: have global on/off switches for auto-time (NTP), and auto-timezone that connman can subscribe to.
301 * dev-setup.c: when running in a container, create a tiny stub udev
302 database with the systemd tag set for all network interfaces found,
303 so that libudev reports them as present, and systemd's .device units
306 * merge unit_kill_common() and unit_kill_context()
308 * introduce ExecCondition= in services
311 - write man page for efi boot generator
312 - honor language efi variables for default language selection (if there are any?)
313 - honor timezone efi variables for default timezone selection (if there are any?)
314 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
316 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
318 * re-enable "make check" for gtk-doc (broken for unknown reason)
320 * fstab: add new mount option x-systemd-after=/foobar/waldo to allow manual dependencies to other mount points
321 https://bugzilla.redhat.com/show_bug.cgi?id=812826
323 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
325 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
328 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
329 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
330 - logind: wakelock/opportunistic suspend support
331 - Add pretty name for seats in logind
332 - logind: allow showing logout dialog from system?
333 - logind: non-local X11 server handling
334 - logind: add equivalent to sd_pid_get_owner_uid() to the D-Bus API
335 - pam: when leaving a session explicitly exclude the ReleaseSession() caller process from the killing spree
336 - logind: GetSessionByPID() should accept 0 as PID value
337 - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
339 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
341 * service: watchdog logic: for testing purposes allow ping, but do not require pong
344 - do not use magic msync() in src/journal/journal-file.c, just call fsync()
345 <alxchk> poettering: looks like msync just calls vfs_fsync
346 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/mm/msync.c#n18
347 - import and delete pstore filesystem content at startup
348 - journald: also get thread ID from client, plus thread name
349 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
350 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
351 - fallback to /dev/log based logging in libsystemd-journal, if we can't log natively?
352 - declare the local journal protocol stable in the wiki interface chart
353 - journal: reuse XZ context
354 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
355 - journald: when dropping msgs due to ratelimit make sure to write
356 "dropped %u messages" not only when we are about to print the next
357 message that works, but alraedy after a short tiemout
358 - check if we can make journalctl by default use --follow mode inside of less if called without args?
359 - maybe add API to send pairs of iovecs via sd_journal_send
360 - journal: when writing journal auto-rotate if time jumps backwards
361 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
362 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
363 and !FOOBAR for events without FOOBAR.
364 - journal: when rotating, copy over old acls/access mode
365 - journal: send out marker messages every now and then, and immediately sync with fdatasync() afterwards, in order to have hourly guaranteed syncs.
366 - 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.
367 - journal: find a way to allow dropping history early, based on priority, other rules
368 - journal: When used on NFS, check payload hashes
369 - journald: check whether it is OK if the client can still modify delivered journal entries
370 - journal live copy, based on libneon (client) and libmicrohttpd (server)
371 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
372 - refuse taking lower-case variable names in sd_journal_send() and friends.
373 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
374 - journal: deal nicely with byte-by-byte copied files, especially regards header
375 - journalctl: expand tabs
376 - journal: store euid in journal if it differs from uid
377 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
378 - Replace utmp, wtmp, btmp, and lastlog completely with journal
379 - Port upower to use the journal for historical power information used in future calculations
382 - document unit_name_mangle()
383 - document that deps in [Unit] sections ignore Alias= fileds in
384 [Install] units of other units, unless those units are disabled
385 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
386 - Document word splitting syntax for ExecStart= and friends
387 - document that units from /etc override those from /usr and /run
388 - document the exit codes when services fail before they are exec()ed
389 - document that service reload may be implemented as service reexec
390 - document in wiki how to map ical recurrence events to systemd timer unit calendar specifications
393 - systemctl list-jobs - show dependencies
394 - add systemctl switch to dump transaction without executing it
395 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
396 - "systemctl disable" on a static unit prints no message and does
397 nothing. "systemctl enable" does nothing, and gives a bad message
398 about it. Should fix both to print nice actionable messages.
399 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
400 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
401 - systemctl enable: improve the success messages (i.e. more human readable, less shell-like)
402 - systemctl enable: fail if target to alias into doesn't exist? maybe show how many units are enabled afterwards?
403 - systemctl: "Journal has been rotated since unit was started." message is misleading
404 - support "systemctl stop foobar@.service" to stop all units matching a certain template
405 - Something is wrong with symlink handling of "autovt@.service" in "systemctl list-unit-files"
407 * introduce ntp.service (or suchlike) as symlink that is used to arbitrate between various NTP implementations
409 * deal with sendmail/postfix exclusivity
412 - configurable jitter for timer events
413 - timer events with system resume
414 - timer units should get the ability to trigger when:
415 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
417 - Support 2012-02~4 as syntax for specifying the fourth to last day of the month.
419 * update the kernel's TZ (sys_tz) when DST changes
421 * sync down the system time to the RTC when:
422 - CLOCK_REALTIME makes jumps (the user explicitely requested a time set)
423 - DST/timezone changes && ntp is active && RTC-in-localtime (never do it without ntp)
424 This takes care of syncing ntpdate updates to the RTC, and DST updates for localtime
425 mode, it will never touch the RTC if the no reliable time source is active or the
426 user did not request anything like it.
428 * if booted in "quiet" mode, and an error happens, turn on status
429 output again, so that the emergency mode isn't totally
430 surprising. Also, terminate plymouth.
432 * libunwind support for coredump pattern hook, and includes this in
433 the message for coredumps. After all, libunwind is now capable to
434 unwind coredumps since a few weeks ago. This probably requires that
435 we have nice support for multi-line messages on display in
436 logs-show.c. Alternatively: use libelfutil, which seems to be the
437 better supported alternative.
439 * figure out relation of --all and --full in the various tools
441 * add libsystemd-password or so to query passwords during boot using the password agent logic
443 * 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().
445 * fedup: add --unit to systemctl switch-root somehow
446 * fedup: don't delete initrd on switch-root
450 - timedated: refuse time changes when NTP is on
452 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
454 * introduce generic AUGMENT_PID=, AUGMENT_DEVICE= fields
456 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
458 * add "provisioning" instructions to setup an empty /etc + /var
459 - used to setup a new container from a shared /usr
460 - superset of tmpfiles model
461 - instructions shipped by packages and stored in /usr/lib/
462 - compose /etc/passwd and /etc/group, copy files
463 - able to create uid + gid used by packages, for file ownership
465 * make repeated alt-ctrl-del presses printing a dump, or even force a reboot without
466 waiting for the timeout
468 * high level net_prio setting in execution context
470 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
472 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab isn't
474 * refuse boot if /etc/machine-id is not useful (or set taint?)
477 - nspawn: consider changing users for -u with su, so that NSS resolving works correctly
478 - nspawn: implement personality changes a la linux32(8)
479 - nspawn: --read-only is not applied recursively to submounts
480 - nspawn: make use of device cgroup controller by default
481 - bind mount read-only the cgroup tree higher than nspawn
482 - nspawn: investigate whether we can support the same as LXC's
483 lxc.network.type=phys mode, and pass through entire network
484 interfaces to the container
485 - nspawn: maybe add a way to drop additional caps, in addition to add additional caps
486 - nspawn: maybe explicitly reset loginuid?
487 - nspawn: make it work for dwalsh and shared /usr containers -- tmpfs mounts as command line parameters, selinux exec context
490 - cryptsetup-generator: allow specification of passwords in crypttab itself
491 - move cryptsetup key caching into kernel keyctl?
492 https://bugs.freedesktop.org/show_bug.cgi?id=54982
493 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
495 * move debug shell to tty6 and make sure this doesn't break the gettys on tty6
497 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
498 https://bugs.freedesktop.org/show_bug.cgi?id=54712
500 * after deserializing sockets in socket.c we should reapply sockopts and things
502 * make timer units go away after they elapsed
504 * http://lists.freedesktop.org/archives/systemd-devel/2012-September/006502.html
505 (network and remote-fs on shutdown)
507 * come up with a nice way to write queue/read_ahead_kb for a block device without interfering with readahead
509 * move PID 1 segfaults to /var/lib/systemd/coredump?
511 * create /sbin/init symlinks from the build system
513 * Query Paul Moore about relabelling socket fds while they are open
515 * allow writing multiple conditions in unit files on one line
517 * explore multiple service instances per listening socket idea
519 * shutdown: don't read-only mount anything when running in container
521 * MountFlags=shared acts as MountFlags=slave right now.
523 * ReadOnlyDirectories= is not applied recursively to submounts
525 * drop PID 1 reloading, only do reexecing (difficult: Reload()
526 currently is properly synchronous, Reexec() is weird, because we
527 can't delay the response properly until we are back, so instead of
528 being properly synchronous we just keep open the fd and close it
529 when done. That means clients don't get a successful method reply,
530 but much rather a disconnect on success.
532 * use opterr = 0 for all getopt tools
534 * properly handle loop back mounts via fstab, especially regards to fsck/passno
536 * allow services with no ExecStart= but with an ExecStop=
538 * dracut-shutdown needs to be ordered before unmounting /boot
540 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
542 * rename "userspace" to "core-os"
545 - syscall filter: add knowledge about compat syscalls
546 - syscall filter: don't enforce no new privs?
547 - syscall filter: option to return EPERM rather than SIGSYS?
548 - syscall filter: port to libseccomp
549 - system-wide seccomp filter
551 * .device aliases need to be implemented with the "following" logic, probably.
553 * load-fragment: when loading a unit file via a chain of symlinks
554 verify that it isn't masked via any of the names traversed.
556 * introduce Type=pid-file
558 * change Requires=basic.target to RequisiteOverride=basic.target
560 * when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
562 * automount: implement expire:
563 - set superblock timeout AUTOFS_DEV_IOCTL_TIMEOUT_CMD
564 - periodically run AUTOFS_DEV_IOCTL_EXPIRE_CMD
565 - every timeout/4 (original autofs logic)
566 - blocking, needs a thread
568 - receive expire packet on pipe if kernel tells the timeout is over
570 - answer expire packet on pipe with AUTOFS_DEV_IOCTL_{READY,FAIL}_CMD
571 - AUTOFS_DEV_IOCTL_EXPIRE_CMD returns
573 * services which create their own subcgroups break cgroup-empty notification (needs to be fixed in the kernel)
575 * ExecOnFailure=/usr/bin/foo
578 - remove src/udev/udev-builtin-firmware.c (CONFIG_FW_LOADER_USER_HELPER=n)
581 - add trigger --subsystem-match=usb/usb_device device
583 * cleanup syslog 'priority' vs. 'level' wording
585 * 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
587 * support container_ttys=
589 * introduce mix of BindTo and Requisite
591 * add DeleteSocketsOnStop=yes|no option to socket units
593 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
595 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
597 * default unix qlen is too small (10). bump sysctl? add sockopt?
599 * save coredump in Windows/Mozilla minidump format
601 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
603 * default to actual 32bit PIDs, via /proc/sys/kernel/pid_max
605 * be able to specify a forced restart of service A where service B depends on, in case B
606 needs to be auto-respawned?
608 * when a bus name of a service disappears from the bus make sure to queue further activation requests
610 * tmpfiles: apply "x" on "D" too (see patch from William Douglas)
612 * for services: don't set $HOME in services unless requested
614 * hide PAM/TCPWrap options in fragment parser when compile time disabled
616 * when we automatically restart a service, ensure we restart its rdeps, too.
618 * allow Type=simple with PIDFile=
619 https://bugzilla.redhat.com/show_bug.cgi?id=723942
621 * move PAM code into its own binary
623 * implement Register= switch in .socket units to enable registration
624 in Avahi, RPC and other socket registration services.
626 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
628 * support sd_notify() style notification when reload begins (RELOADING=1), reload is finished (READY=1), and add ReloadSignal= then to use in combination
630 * support sd_notify() style notification when shutting down, to make auto-exit bus services work (STOPPING=1)
632 * verify that the AF_UNIX sockets of a service in the fs still exist
633 when we start a service in order to avoid confusion when a user
634 assumes starting a service is enough to make it accessible
636 * support User= and Group= attributes for AF_UNIX sockets.
638 * Make it possible to set the keymap independently from the font on
639 the kernel cmdline. Right now setting one resets also the other.
641 * and a dbus call to generate target from current state
644 - drop /.readahead on bigger upgrades with yum
645 - move readahead files into /var (look for them with .path units?)
646 - readahead: use BTRFS_IOC_DEFRAG_RANGE instead of BTRFS_IOC_DEFRAG ioctl, with START_IO
647 - readahead: when bumping /sys readahead variable save mtime and compare later to detect changes
648 - readahead: make use of EXT4_IOC_MOVE_EXT, as used by http://e4rat.sourceforge.net/
650 * add support for /bin/mount -s
652 * GC unreferenced jobs (such as .device jobs)
654 * write blog stories about:
655 - hwdb: what belongs into it, lsusb
656 - enabling dbus services
658 - how to make changes to sysctl and sysfs attributes
660 - how to pass throw-away units to systemd, or dynamically change properties of existing units
661 - how to integrate cgconfig and suchlike with systemd
662 - testing with Harald's awesome test kit
664 - how to develop against journal browsing APIs
665 - the journal HTTP iface
666 - non-cgroup resource management
667 - dynamic resource management with cgroups
668 - refreshed, longer missions statement
669 - calendar time events
670 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
671 - how to create your own target
672 - instantiated apache, dovecot and so on
673 - hooking a script into various stages of shutdown/rearly booot
675 * allow port=0 in .socket units
677 * support systemd.mask= on the kernel command line.
679 * recreate systemd's D-Bus private socket file on SIGUSR2
681 * Support --test based on current system state
683 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
685 * maybe introduce ExecRestartPre=
687 * dot output for --test showing the 'initial transaction'
689 * port over to LISTEN_FDS/LISTEN_PID:
690 - rpcbind (/var/run/rpcbind.sock!) HAVEPATCH
694 - libvirtd (/var/run/libvirt/libvirt-sock-ro)
695 - bluetoothd (/var/run/sdp! @/org/bluez/audio!)
698 * fingerprint.target, wireless.target, gps.target, netdevice.target
700 * io priority during initialization
702 * drop cap bounding set in readahead and other services
705 - figure out a simple way to wait for journal events in a way that
707 - add documentation to systemd.daemon
710 - plot per-process IO utilization
711 - group processes based on service association (cgroups)
712 - document initcall_debug
713 - kernel cmdline "bootchart" option for simplicity?
715 * systemd-run is missing zsh completion scripts
721 - natively watch for dbus-*.service symlinks (PENDING)
722 - allow specification of socket mode/umask when allocating DBusServer
723 - allow disabling of fd passing when connecting a AF_UNIX connection
724 - allow disabling of UID passing for AUTH EXTERNAL
725 - always pass cred data along each message
726 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
728 * fix alsa mixer restore to not print error when no config is stored
730 * make cryptsetup lower --iter-time
732 * patch kernel for xattr support in /dev, /proc/, /sys?
734 * NTP: the kernel's 11-minutes-mode syncs the system time to the RTC, but only
735 in an ~30 minutes window. It does not adjust larger differences. Find a way
736 to tell the kernel, to always do a full time sync when the RTC is in UTC and
737 we are in 11-minutes-mode. When we trust the system time to NTP we also want
740 * kernel: add device_type = "fb", "fbcon" to class "graphics"
742 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
744 * dbus upstream still refers to dbus.target and shouldn't
746 * dbus: in fedora, make /var/lib/dbus/machine-id a symlink to /etc/machine-id
748 * add "# export SYSTEMD_PAGER=" to bash login
750 * /usr/bin/service should actually show the new command line
752 * 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=
754 * fedora: F20: go timer units all the way, leave cron.daily for cron
756 * neither pkexec nor sudo initialize environ[] from the PAM environment?
758 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
762 * look for close() vs. close_nointr() vs. close_nointr_nofail()
764 * check for strerror(r) instead of strerror(-r)
766 * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
768 * %m in printf() instead of strerror(errno);
772 * set_put(), hashmap_put() return values check. i.e. == 0 doesn't free()!
774 * use secure_getenv() instead of getenv() where appropriate
776 * link up selected blog stories from man pages and unit files Documentation= fields
778 Scheduled for removal or fixing:
780 * xxxOverridable dependencies (probably: fix)
