2 * enabling an instance unit creates a pointless link, and
3 the unit will be started with getty@getty.service:
4 $ systemctl enable getty@.service
5 ln -s '/usr/lib/systemd/system/getty@.service' '/etc/systemd/system/getty.target.wants/getty@.service'
7 * Dangling symlinks of .automount unit files in .wants/ directories, set up
8 automount points even when the original .automount file did not exist
9 anymore. Only the .mount unit was still around.
11 * properly handle .mount unit state tracking when two mount points are stacked one on top of another on the exact same mount point.
13 * shorten the message to sane length:
15 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.
17 * systemctl --root=container/ set-default ... is totally borked.
21 * Fedora: when installing fedora with yum --installroot /var/run is a directory, not a symlink
22 https://bugzilla.redhat.com/show_bug.cgi?id=975864
24 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
26 * Fedora: post FPC ticket to move add %tmpfiles_create to the packaging guidelines
30 * improve journalctl performance by loading journal files
31 lazily. Encode just enough information in the file name, so that we
32 don't have to open it to know that it is not interesting for us, for
33 the most common operations.
35 * support transient mount units
37 * Imply DevicePolicy=closed when PrivateDevices= is used
39 * add an "input" group to udev logic and add all input devices to it
41 * libsystemd-login: implement getpeer_unit(), get_peer_slice(), ...
43 * machined: provide calls GetMachineByAddress() on the manager
44 interface to get the machine for a local IP address, and
45 GetAddress() on the Machine interface to get the Address for a
46 machine. Implement via forking off child process which quickly joins
47 the cotnainer and passes data to parent. Show this in "machinectl
48 status", and use it to implement NSS module to provide automatic
49 name resolution for containers.
51 * add generator that pulls in systemd-network from containers when
52 CAP_NET_ADMIN is set, more than the loopback device is defined, even
53 when it is otherwise off
55 * MessageQueueMessageSize= and RLimitFSIZE= (and suchlike) should use parse_iec_size().
57 * "busctl status" works only as root on dbus1, since we cannot read
60 * systemctl (and possibly related tools): support a new switch that
61 allows enumerating units in local containers recursively. "systemctl
62 list-units -R" or so should not only lists on the host, but also the
63 services in all containers in a pretty way, to give an overview of
64 the entire system. Also, maybe add "systemctl list-machines" which
65 works like "machinectl list" but includes information about the
66 health status of each registered machine. For that we should
67 probably implement something that encodes the system health status
68 in a single enum state, i.e. something like a system-wide state
69 starting → running → failed → stopping, that is based on the current
70 job queue and a check for failed services. Maybe then change
71 "systemctl status" without args to output this state along with a
72 selection of other data, such as the uptime or so.
74 * implement Distribute= in socket units to allow running multiple
75 service instances processing the listening socket, and open this up
78 * add a timelimit to generator invocation
80 * socket units: support creating sockets in different namespace,
81 opening it up for JoinsNamespaceOf=. This would require to fork off
82 a tiny process that joins the namespace and creates/binds the socket
83 and passes this back to PID1 via SCM_RIGHTS. This also could be used
84 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
86 * New service property: maximum CPU and wallclock runtime for a service
88 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
89 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
90 should SIGSTOP all unit processes in a loop until all processes of
91 it are fully stopped. This can later be used for app management by
92 desktop UIs such as gnome-shell to freeze apps that are not visible
93 on screen, not unlike how job control works on the shell
96 - busctl zsh completion is outdated
97 - systemd-nspawn -Z/-L/-q is missing for zsh
98 - manager property enumeration was broken when systemd moved to /usr/lib/
101 - implement per-slice CPUFairScheduling=1 switch
102 - handle jointly mounted controllers correctly
103 - introduce high-level settings for RT budget, swappiness
104 - how to reset dynamically changed unit cgroup attributes sanely?
105 - when reloading configuration, apply new cgroup configuration
106 - when recursively showing the cgroup hierarchy, optionally also show
107 the hierarchies of child processes
110 - allow creating auxiliary units with the same call
111 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
112 - ensure scope units may be started only a single time
114 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
116 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
118 * machined, localed: when we try to kill an empty cgroup, generate an ESRCH error over the bus
120 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
122 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
124 * unify dispatch table in systemctl_main() and friends
126 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
128 * socket-proxyd: Use sd-resolve to resolve the server address
130 * 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
132 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
134 * If we try to find a unit via a dangling symlink, generate a clean
135 error. Currently, we just ignore it and read the unit from the search
138 * refuse boot if /etc/os-release is missing or /etc/machine-id cannot be set up
140 * given that logind now lets PID 1 do all nasty work, we can
141 probably reduce the capability set it retains substantially.
142 (we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
144 * btrfs raid assembly: some .device jobs stay stuck in the queue
146 * make sure gdm doesn't use multi-user-x but the new default X configuration file, and then remove multi-user-x from systemd
148 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
150 * load .d/*.conf dropins for device units
152 * gparted needs to disable auto-activation of mount units somehow, or
153 maybe we should stop doing auto-activation of this after boot
154 entirely. https://bugzilla.gnome.org/show_bug.cgi?id=701676
155 Maybe take a BSD lock at the disk device node and teach udev to
156 check for that and suppress event handling.
158 * something pulls in pcre as shared object dependency into our daemons such as hostnamed.
160 * allow implementation of InaccessibleDirectories=/ plus
161 ReadOnlyDirectories=... for whitelisting files for a service.
164 - when kdbus doesn't take our message without memfds, try again with memfds
165 - implement monitor logic
166 - see if we can drop more message validation on the sending side
167 - add API to clone sd_bus_message objects
168 - systemd-bus-proxyd needs to enforce good old XML policy
169 - upload minimal kdbus policy into the kernel at boot
170 - kdbus: matches against source or destination pids for an "strace -p"-like feel. Problem: The PID info needs to be available in userspace too...
171 - longer term: priority inheritance
172 - check sender of response messages
175 - NameLost/NameAcquired obsolete
177 - "const" properties (posted)
178 - port exit-on-idle logic to byebye ioctl
179 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
180 - allow updating attach flags during runtime
181 - pid1: peek into activating message when activating a service
182 - test bloom filter generation indexes
183 - introduce sd_bus_emit_object_added()/sd_bus_emit_object_removed() that automatically includes the build-in interfaces in the list
184 - port to sd-resolve for connecting to TCP dbus servers
185 - constructors for bus messages should probably not be OK with a NULL bus pointer
188 - allow multiple signal handlers per signal?
190 * in the final killing spree, detect processes from the root directory, and
191 complain loudly if they have argv[0][0] == '@' set.
192 https://bugzilla.redhat.com/show_bug.cgi?id=961044
194 * investigate endianness issues of UUID vs. GUID
196 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
197 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
199 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
201 * add a pam module that on password changes updates any LUKS slot where the password matches
203 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
205 * timedatctl, localectl: possibly make some commands work without the daemon, for chroot situations...
207 * timedatectl: print a nicer message when enabling ntp fails because ntpd/chrony are not installed
209 * cgtop: make cgtop useful in a container
212 - add 'set -e' to scripts in test/
213 - make stuff in test/ work with separate output dir
215 * systemctl delete x.snapshot leaves no trace in logs (at least at default level).
217 * make the coredump collector tool move itself into the user's cgroup
218 so that the coredump is properly written to the user's own journal
221 * seems that when we follow symlinks to units we prefer the symlink
222 destination path over /etc and /usr. We shouldn't do that. Instead
223 /etc should always override /run+/usr and also any symlink
226 * when isolating, try to figure out a way how we implicitly can order
227 all units we stop before the isolating unit...
229 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
231 * after all byte-wise realloc() is slow, even on glibc, so i guess we
232 need manual exponential loops after all
234 * BootLoaderSpec: drop allowing ext234 for $BOOT. Clarify that the
235 kernel has to be in $BOOT. Clarify that the boot loader should be
236 installed to the ESP. Define a way how an installer can figure out
237 whether a BLS compliant boot loader is installed.
239 * think about requeuing jobs when daemon-reload is issued? usecase:
240 the initrd issues a reload after fstab from the host is accessible
241 and we might want to requeue the mounts local-fs acquired through
244 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
246 * journal-or-kmsg is currently broken? See reverted commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
248 * remove any syslog support from log.c -- we probably can't do this before split-off udev is gone for good
250 * shutdown logging: store to EFI var, and store to USB stick?
252 * write UI tool that pops up emergency messages from the journal as notification
254 * think about window-manager-run-as-user-service problem: exit 0 → activate shutdown.target; exit != 0 → restart service
256 * use "log level" rather than "log priority" everywhere
258 * timedate: have global on/off switches for auto-time (NTP), and auto-timezone that connman can subscribe to.
260 * merge unit_kill_common() and unit_kill_context()
262 * introduce ExecCondition= in services
265 - write man page for efi boot generator
266 - honor language efi variables for default language selection (if there are any?)
267 - honor timezone efi variables for default timezone selection (if there are any?)
268 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
270 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
272 * re-enable "make check" for gtk-doc (broken for unknown reason)
274 * fstab: add new mount option x-systemd-after=/foobar/waldo to allow manual dependencies to other mount points
275 https://bugzilla.redhat.com/show_bug.cgi?id=812826
277 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
279 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
282 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
283 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
284 - logind: wakelock/opportunistic suspend support
285 - Add pretty name for seats in logind
286 - logind: allow showing logout dialog from system?
287 - logind: add equivalent to sd_pid_get_owner_uid() to the D-Bus API
288 - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
289 - when logging out, remove user-owned sysv and posix IPC objects
290 - session scopes/user unit: add RequiresMountsFor for the home directory of the user
291 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
292 - if pam_systemd is invoked by su from a process that is outside of a
293 any session we should probably just become a NOP, since that's
294 usually not a real user session but just some system code that just
297 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
299 * service: watchdog logic: for testing purposes allow ping, but do not require pong
302 - import and delete pstore filesystem content at startup
303 - journald: also get thread ID from client, plus thread name
304 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
305 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
306 - fallback to /dev/log based logging in libsystemd-journal, if we can't log natively?
307 - declare the local journal protocol stable in the wiki interface chart
308 - journal: reuse XZ context
309 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
310 - journald: when dropping msgs due to ratelimit make sure to write
311 "dropped %u messages" not only when we are about to print the next
312 message that works, but alraedy after a short tiemout
313 - check if we can make journalctl by default use --follow mode inside of less if called without args?
314 - maybe add API to send pairs of iovecs via sd_journal_send
315 - journal: when writing journal auto-rotate if time jumps backwards
316 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
317 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
318 and !FOOBAR for events without FOOBAR.
319 - journal: send out marker messages every now and then, and immediately sync with fdatasync() afterwards, in order to have hourly guaranteed syncs.
320 - 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.
321 - journal: find a way to allow dropping history early, based on priority, other rules
322 - journal: When used on NFS, check payload hashes
323 - journald: check whether it is OK if the client can still modify delivered journal entries
324 - journal live copy, based on libneon (client) and libmicrohttpd (server)
325 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
326 - refuse taking lower-case variable names in sd_journal_send() and friends.
327 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
328 - journal: deal nicely with byte-by-byte copied files, especially regards header
329 - journal: store euid in journal if it differs from uid
330 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
331 - Replace utmp, wtmp, btmp, and lastlog completely with journal
332 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
333 - tmpfiles: when applying ownership to /run/log/journal, also do this for the journal fails contained in it
334 - when a kernel driver logs in a tight loop, we should ratelimit that too.
335 - journald: optionally, log debug messages to /run but everything else to /var
336 - journald: when we drop syslog messages because the syslog socket is
337 full, make sure to write how many messages are lost as first thing
338 to syslog when it works again.
339 - journald: make sure ratelimit is actually really per-service with the new cgroup changes
340 - change systemd-journal-flush into a service that stays around during
341 boot, and causes the journal to be moved back to /run on shutdown,
342 so that we don't keep /var busy. This needs to happen synchronously,
343 hence doing this via signals is not going to work.
346 - document that deps in [Unit] sections ignore Alias= fields in
347 [Install] units of other units, unless those units are disabled
348 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
349 - document the exit codes when services fail before they are exec()ed
350 - document that service reload may be implemented as service reexec
351 - document in wiki how to map ical recurrence events to systemd timer unit calendar specifications
352 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
353 - document systemd-journal-flush.service properly
354 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
355 - man: document the very specific env the shutdown drop-in tools live in
356 - man: extend runlevel(8) to mention that runlevels suck, and are dead. Maybe add runlevel(7) with a note about that too
357 - man: add more examples to man pages
358 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
361 - systemctl list-jobs - show dependencies
362 - add systemctl switch to dump transaction without executing it
363 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
364 - "systemctl disable" on a static unit prints no message and does
365 nothing. "systemctl enable" does nothing, and gives a bad message
366 about it. Should fix both to print nice actionable messages.
367 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
368 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
369 - systemctl enable: improve the success messages (i.e. more human readable, less shell-like)
370 - systemctl enable: fail if target to alias into doesn't exist? maybe show how many units are enabled afterwards?
371 - systemctl: "Journal has been rotated since unit was started." message is misleading
372 - support "systemctl stop foobar@.service" to stop all units matching a certain template
373 - Something is wrong with symlink handling of "autovt@.service" in "systemctl list-unit-files"
374 - rework wait filter to not require match callback
375 - better error message if you run systemctl without systemd running
376 - systemctl status output should should include list of triggering units and their status
377 - in systemctl list-timers show time triggering units ran last
380 - "systemctl mask" should find all names by which a unit is accessible
381 (i.e. by scanning for symlinks to it) and link them all to /dev/null
382 - "systemctl disable" of a unit instance removes all symlinks, but should
383 only remove the instance symlink (systemctl disable of a template
384 unit however should remove them all).
385 - systemctl list-unit-files should list generated files (and probably with a new state "generated" for them, or so)
386 - systemctl: maybe add "systemctl add-wants" or so...
388 * introduce ntp.service (or suchlike) as symlink that is used to arbitrate between various NTP implementations
390 * deal with sendmail/postfix exclusivity
393 - timer events with system resume
394 - timer units should get the ability to trigger when:
395 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
397 - Support 2012-02~4 as syntax for specifying the fourth to last day of the month.
398 - calendarspec: support value ranges with ".." notation. Example: 2013-4..8-1
399 - 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
400 - Modulate timer frequency based on battery state
401 - anacron-like feature
403 * update the kernel's TZ (sys_tz) when DST changes
405 * sync down the system time to the RTC when:
406 - CLOCK_REALTIME makes jumps (the user explicitely requested a time set)
407 - DST/timezone changes && ntp is active && RTC-in-localtime (never do it without ntp)
408 This takes care of syncing ntpdate updates to the RTC, and DST updates for localtime
409 mode, it will never touch the RTC if the no reliable time source is active or the
410 user did not request anything like it.
412 * if booted in "quiet" mode, and an error happens, turn on status
413 output again, so that the emergency mode isn't totally
414 surprising. Also, terminate plymouth.
416 * libunwind support for coredump pattern hook, and includes this in
417 the message for coredumps. After all, libunwind is now capable to
418 unwind coredumps since a few weeks ago. This probably requires that
419 we have nice support for multi-line messages on display in
420 logs-show.c. Alternatively: use libelfutil, which seems to be the
421 better supported alternative.
423 * add libsystemd-password or so to query passwords during boot using the password agent logic
425 * 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().
427 * fedup: add --unit to systemctl switch-root somehow
428 * fedup: don't delete initrd on switch-root
431 * timedated: refuse time changes when NTP is on
433 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
435 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
437 * add "provisioning" instructions to setup an empty /etc + /var
438 - used to setup a new container from a shared /usr
439 - superset of tmpfiles model
440 - instructions shipped by packages and stored in /usr/lib/
441 - compose /etc/passwd and /etc/group, copy files
442 - able to create uid + gid used by packages, for file ownership
444 * make repeated alt-ctrl-del presses printing a dump, or even force a reboot without
445 waiting for the timeout
447 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
449 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab isn't
452 - nspawn: consider changing users for -u with /usr/bin/getent, so that NSS resolving works correctly
453 - nspawn: --read-only is not applied recursively to submounts
454 - bind mount read-only the cgroup tree higher than nspawn
455 - nspawn: make it work for dwalsh and shared /usr containers -- tmpfs mounts as command line parameters
456 - refuses to boot containers without /etc/machine-id (OK?), and with empty /etc/machine-id (not OK).
457 - support taking a btrfs snapshot at startup and dropping it afterwards
458 - maybe: hookup nspawn and PrivateNetwork=yes with "ip netns"
459 - allow booting disk images with a GPT signature using the bootloaderspec partition uuids
460 - generate predictable mac addresses for the netdev we create (host0), maybe based on guest's machine
461 name and machine-id of host (?)
464 - cryptsetup-generator: allow specification of passwords in crypttab itself
465 - move cryptsetup key caching into kernel keyctl?
466 https://bugs.freedesktop.org/show_bug.cgi?id=54982
467 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
469 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
470 https://bugs.freedesktop.org/show_bug.cgi?id=54712
472 * after deserializing sockets in socket.c we should reapply sockopts and things
474 * make timer units go away after they elapsed
476 * http://lists.freedesktop.org/archives/systemd-devel/2012-September/006502.html
477 (network and remote-fs on shutdown)
479 * come up with a nice way to write queue/read_ahead_kb for a block device without interfering with readahead
481 * move PID 1 segfaults to /var/lib/systemd/coredump?
483 * create /sbin/init symlinks from the build system
485 * Query Paul Moore about relabelling socket fds while they are open
487 * allow writing multiple conditions in unit files on one line
489 * explore multiple service instances per listening socket idea
491 * MountFlags=shared acts as MountFlags=slave right now.
493 * ReadOnlyDirectories= is not applied recursively to submounts
495 * drop PID 1 reloading, only do reexecing (difficult: Reload()
496 currently is properly synchronous, Reexec() is weird, because we
497 can't delay the response properly until we are back, so instead of
498 being properly synchronous we just keep open the fd and close it
499 when done. That means clients don't get a successful method reply,
500 but much rather a disconnect on success.
502 * properly handle loop back mounts via fstab, especially regards to fsck/passno
504 * allow services with no ExecStart= but with an ExecStop=
506 * dracut-shutdown needs to be ordered before unmounting /boot
508 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
510 * rename "userspace" to "core-os"
512 * syscall filter: optionally don't enforce no new privs?
514 * load-fragment: when loading a unit file via a chain of symlinks
515 verify that it isn't masked via any of the names traversed.
517 * introduce Type=pid-file
519 * change Requires=basic.target to RequisiteOverride=basic.target
521 * when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
523 * automount: implement expire:
524 - set superblock timeout AUTOFS_DEV_IOCTL_TIMEOUT_CMD
525 - periodically run AUTOFS_DEV_IOCTL_EXPIRE_CMD
526 - every timeout/4 (original autofs logic)
527 - blocking, needs a thread
529 - receive expire packet on pipe if kernel tells the timeout is over
531 - answer expire packet on pipe with AUTOFS_DEV_IOCTL_{READY,FAIL}_CMD
532 - AUTOFS_DEV_IOCTL_EXPIRE_CMD returns
534 * ExecOnFailure=/usr/bin/foo
537 - remove src/udev/udev-builtin-firmware.c (CONFIG_FW_LOADER_USER_HELPER=n)
540 - add trigger --subsystem-match=usb/usb_device device
541 - reimport udev db after MOVE events for devices without dev_t
543 * 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
545 * introduce mix of BindTo and Requisite
547 * add DeleteSocketsOnStop=yes|no option to socket units
549 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
551 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
553 * default unix qlen is too small (10). bump sysctl? add sockopt?
555 * save coredump in Windows/Mozilla minidump format
557 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
559 * default to actual 32bit PIDs, via /proc/sys/kernel/pid_max
561 * be able to specify a forced restart of service A where service B depends on, in case B
562 needs to be auto-respawned?
564 * when a bus name of a service disappears from the bus make sure to queue further activation requests
567 - check systemd-tmpfiles for selinux context hookup for mknod(), symlink() and similar
568 - apply "x" on "D" too (see patch from William Douglas)
570 * for services: don't set $HOME in services unless requested
572 * hide PAM/TCPWrap options in fragment parser when compile time disabled
574 * when we automatically restart a service, ensure we restart its rdeps, too.
576 * allow Type=simple with PIDFile=
577 https://bugzilla.redhat.com/show_bug.cgi?id=723942
579 * move PAM code into its own binary
581 * implement Register= switch in .socket units to enable registration
582 in Avahi, RPC and other socket registration services.
584 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
586 * support sd_notify() style notification when reload begins (RELOADING=1), reload is finished (READY=1), and add ReloadSignal= then to use in combination
588 * support sd_notify() style notification when shutting down, to make auto-exit bus services work (STOPPING=1)
590 * verify that the AF_UNIX sockets of a service in the fs still exist
591 when we start a service in order to avoid confusion when a user
592 assumes starting a service is enough to make it accessible
594 * support User= and Group= attributes for AF_UNIX sockets. (difficult, requires NSS from PID 1?)
596 * Make it possible to set the keymap independently from the font on
597 the kernel cmdline. Right now setting one resets also the other.
599 * and a dbus call to generate target from current state
602 - drop /.readahead on bigger upgrades with yum
603 - move readahead files into /var (look for them with .path units?)
604 - readahead: use BTRFS_IOC_DEFRAG_RANGE instead of BTRFS_IOC_DEFRAG ioctl, with START_IO
605 - readahead: when bumping /sys readahead variable save mtime and compare later to detect changes
606 - readahead: make use of EXT4_IOC_MOVE_EXT, as used by http://e4rat.sourceforge.net/
608 * add support for /bin/mount -s
610 * GC unreferenced jobs (such as .device jobs)
612 * write blog stories about:
613 - hwdb: what belongs into it, lsusb
614 - enabling dbus services
616 - how to make changes to sysctl and sysfs attributes
618 - how to pass throw-away units to systemd, or dynamically change properties of existing units
619 - how to integrate cgconfig and suchlike with systemd
620 - testing with Harald's awesome test kit
622 - how to develop against journal browsing APIs
623 - the journal HTTP iface
624 - non-cgroup resource management
625 - dynamic resource management with cgroups
626 - refreshed, longer missions statement
627 - calendar time events
628 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
629 - how to create your own target
630 - instantiated apache, dovecot and so on
631 - hooking a script into various stages of shutdown/rearly booot
633 * allow port=0 in .socket units
635 * support systemd.mask= on the kernel command line.
637 * recreate systemd's D-Bus private socket file on SIGUSR2
639 * Support --test based on current system state
641 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
643 * maybe introduce ExecRestartPre=
645 * dot output for --test showing the 'initial transaction'
647 * fingerprint.target, wireless.target, gps.target, netdevice.target
649 * io priority during initialization
651 * drop cap bounding set in readahead and other services
654 - figure out a simple way to wait for journal events in a way that
656 - add documentation to systemd.daemon
659 - plot per-process IO utilization
660 - group processes based on service association (cgroups)
661 - document initcall_debug
662 - kernel cmdline "bootchart" option for simplicity?
665 - Make sure ID_PATH is always exported and complete for
666 network devices where possible, so we can safely rely
670 - add support for exiting containers without reading them fully first
671 - add support for more attribute types
674 - add more keys to [Route] and [Address] sections
675 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
676 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
677 - add reduced [Link] support to .network files
678 - add IPv4LL tests (inspire by DHCP)
679 - add IPv4LL to man pages. Explain coexistance between DHCP
680 - add Scope= parsing option for [Network]
681 - change LL address generation and make it predictable like get_mac() (link-config.c)
682 - have smooth transition from LL to routable address, without disconnecting clients.
687 - natively watch for dbus-*.service symlinks (PENDING)
688 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
690 * fix alsa mixer restore to not print error when no config is stored
692 * make cryptsetup lower --iter-time
694 * patch kernel for xattr support in /dev, /proc/, /sys?
696 * NTP: the kernel's 11-minutes-mode syncs the system time to the RTC, but only
697 in an ~30 minutes window. It does not adjust larger differences. Find a way
698 to tell the kernel, to always do a full time sync when the RTC is in UTC and
699 we are in 11-minutes-mode. When we trust the system time to NTP we also want
702 * kernel: add device_type = "fb", "fbcon" to class "graphics"
704 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
706 * dbus upstream still refers to dbus.target and shouldn't
708 * dbus: in fedora, make /var/lib/dbus/machine-id a symlink to /etc/machine-id
710 * add "# export SYSTEMD_PAGER=" to bash login
712 * /usr/bin/service should actually show the new command line
714 * 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=
716 * fedora: F20: go timer units all the way, leave cron.daily for cron
718 * neither pkexec nor sudo initialize environ[] from the PAM environment?
720 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
724 * look for close() vs. close_nointr() vs. close_nointr_nofail()
726 * check for strerror(r) instead of strerror(-r)
728 * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
732 * set_put(), hashmap_put() return values check. i.e. == 0 doesn't free()!
734 * use secure_getenv() instead of getenv() where appropriate
736 * link up selected blog stories from man pages and unit files Documentation= fields
738 Scheduled for removal or fixing:
740 * xxxOverridable dependencies (probably: fix)
