2 * there is nothing to warn about here :)
3 $ systemctl stop systemd-udevd.service systemd-udevd-kernel.socket systemd-udevd-control.socket
4 Warning: Stopping systemd-udevd.service, but it can still be activated by:
5 systemd-udevd-control.socket
6 systemd-udevd-kernel.socket
8 * kill /etc/timezone handling entirely? What does it provide?
9 - /etc/localtime carries the same information already:
10 $ ls -l /etc/localtime; cat /etc/timezone
11 lrwxrwxrwx 1 root root 33 Jul 27 09:55 /etc/localtime -> /usr/share/zoneinfo/Europe/Berlin
13 - systemd enforces /usr to be available at bootup, so we can
14 enforce the use of the symlink
16 * check systemd-tmpfiles for selinux context hookup for mknod(), symlink() and similar
18 * swap units that are activated by one name but shown in the kernel under another are semi-broken
20 * make anaconda write timeout=0 for encrypted devices
22 * Dangling symlinks of .automount unit files in .wants/ directories, set up
23 automount points even when the original .automount file did not exist
24 anymore. Only the .mount unit was still around.
26 * make polkit checks async
28 * properly handle .mount unit state tracking when two mount points are stacked one on top of another on the exact same mount point.
30 * we pull src/core/manager.h into src/shared/src/shared/path-lookup.c which is the wrong direction
31 rename enum "ManagerRunningAs" to "SystemdRunningAs" and move it to shared/
33 * crash happens when running a service as forking and then changing it to simple and reloading.

45 * support *static* (/run) hibernate inhibitors. All rpm -i actions should completely prevent any
46 sort of hibernate action until the next reboot. If the kernel or any other base tool is replaced
47 by rpm, the resume path might fail, the for resume needed kernel might even be uninstalled, and
48 the whole situation leads directly to data loss.
52 * There's something wrong with escaping unit names: http://lists.freedesktop.org/archives/systemd-devel/2012-August/006292.html
54 * cleanup ellipsation for log output in journalctl and systemctl status: have a sane way to disable ellipsation, and disable it by default when invoked in less/more
56 * enforce limits on fds openened by socket units
58 * proper service failure code for services which hit the restart limit
60 * explore multiple service instances per listening socket idea
62 * testing tool for socket activation: some binary that listens on a socket and passes it on using the usual socket activation protocol to some server.
64 * journald: add symlinks and device names to kernel messages
66 * maybe make systemd-detect-virt suid? or use fscaps?
68 * consider using __secure_getenv() instead of getenv() in libs
70 * journald: automatic rekeying with no log messages doesn't appear to work
72 * man: document in ExecStart= explicitly that we don't take shell command lines, only executable names with arguments
74 * shutdown: don't read-only mount anything when running in container
76 * nspawn: --read-only is not applied recursively to submounts
78 * MountFlags=shared acts as MountFlags=slave right now.
80 * ReadOnlyDirectories= is not applied recursively to submounts
82 * drop PID 1 reloading, only do reexecing (difficult: Reload()
83 currently is properly synchronous, Reexec() is weird, because we
84 can't delay the response properly until we are back, so instead of
85 being properly synchronous we just keep open the fd and close it
86 when done. That means clients don't get a succesful method reply,
87 but much rather a disconnect on success.
89 * document that service reload may be implemented as service reexec
91 * add option to reconfigure success exit codes/signals for services
93 * remember which condition failed for services, not just the fact that something failed
95 * use opterr = 0 for all getopt tools
97 * properly handle loop back mounts via fstab, especially regards to fsck/passno
99 * allow services with no ExecStart= but with an ExecStop=
101 * add proper journal support to "systemctl --user status ..."
103 * add _SYSTEMD_USER_UNIT= field to journal entries
105 * remove Fedora /dev/null logic from localed.c, now that system-config-keyboard is gone
106 delete /etc/X11/xorg.conf.d/00-system-setup-keyboard.conf from spec file
108 * journal: expose current disk usage
110 * dracut-shutdown needs to be ordered before unmounting /boot
112 * wiki: document new logind LockSessions() call
114 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
116 * logind: different policy actions for idle, suspend, shutdown blockers: allow idle blockers by default, don't allow suspend blockers by default
118 * install README to /etc/rc.d/init.d (if support for that is enabled) helping people who use "ls" there to figure out which services exist.
120 * logind: ignore inactive login screens when checking whether power key should be handled
122 * rename "userspace" to "core-os"
124 * systemctl: "Journal has been rotated since unit was started." message is misleading
126 * syscall filter: add knowledge about compat syscalls
128 * syscall filter: don't enforce no new privs?
130 * syscall filter: option to return EPERM rather than SIGSYS?
132 * syscall filter: port to libseccomp
134 * logind: wakelock/opportunistic suspend support
136 * switch-root: sockets need relabelling
138 * segfault in journalctl during /var migration
140 * systemd-analyze post-boot is broken for initrd
142 * man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
144 * journalctl should complain if run with uid != 0 and no persistent logs exist
146 * .device aliases need to be implemented with the "following" logic, probably.
148 * refuse taking lower-case variable names in sd_journal_send() and friends.
150 * load-fragment: when loading a unit file via a chain of symlinks
151 verify that it isn't masked via any of the names traversed.
153 * journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
158 * introduce Type=pid-file
160 * systemctl list-unit-files appears to be broken for symlinked units in /usr/lib
162 * maybe allow services with ExecStop= set, but no ExecStart=?
164 * efi: implement /forcefsck as uefi variables thus not requiring file system altering to trigger a file system check
166 * efi: honour language efi variables for default language selection
168 * efi: honour timezone efi variables for default timezone selection
170 * efi: automatically mount EFI partition to /boot if no such entry exists in /etc/fstab and /boot is empty
171 gummiboot exports the EFI system partion (ESP) device:
172 /sys/firmware/efi/vars/LoaderDeviceIdentifier-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
173 Acpi(PNP0A03,0)/Pci(1F|2)/?/HD(Part1,Sig1FCBC57F-4BFC-4C2B-91A3-9C84FBCD9AF1)
174 '/' is the separator for the device path list
175 HD(Part1,Sig1FCBC57F-4BFC-4C2B-91A3-9C84FBCD9AF1) contains the GPT UUID of the ESP
177 * read the bootloader performance data (raw TSC) in systemd-analyze
178 /sys/firmware/efi/vars/LoaderTicksExec-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
180 /sys/firmware/efi/vars/LoaderTicksInit-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
182 /sys/firmware/efi/vars/LoaderTicksStartMenu-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
183 (only set if the menu was active)
185 * change Requires=basic.target to RequisiteOverride=basic.target
187 * support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
189 * systemctl: when stopping a service which has triggres and warning about it actually check the TriggeredBy= deps fields
191 * journal: hook up with EFI firmware log, new kmsg logic
193 * handle C-A-Del in logind, like the power/suspend buttons?
195 * nspawn: make use of device cgroup contrller by default
197 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
199 * when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
201 * readahead: when bumping /sys readahead variable save mtime and compare later to detect changes
203 * (attempt to) make Debianites happy:
204 - implement .d/ auto includes for unit files
205 - add syntax to reset ExecStart= lists (and similar)
207 * manipulate CPU governor during boot, set it to performance
209 * steal SBF management from the kernel
211 * delay journal /var writeout to after boot if SBF is clean
213 * move passno parsing to fstab generator
215 * improve !/proc/*/loginuid situation: make /proc/*/loginuid less dependent on CONFIG_AUDIT,
216 or use the users cgroup information when /proc/*/loginuid is not available.
218 * pam_systemd: try to get old session id from cgroup, if audit sessionid cannot be determined
220 * pam: when leaving a session explicitly exclude the ReleaseSession() caller process from the killing spree
222 * maybe introduce ~/.config/locale.conf and apply it within PAM
224 * readahead: make use of EXT4_IOC_MOVE_EXT, as used by http://e4rat.sourceforge.net/
226 * automount: implement expire
228 * logind: auto-suspend, auto-shutdown:
229 IdleAction=(none|suspend|opportunistic|hibernate|poweroff)
231 SessionIdleMode=(explicit|ignore|login)
232 ForceShutdown=(yes|no)
234 * services which create their own subcgroups break cgroup-empty notification (needs to be fixed in the kernel)
236 * don't delete /tmp/systemd-namespace-* before a process is gone down
238 * vconsole: implement setterm -store -foreground xxx --background zzz
240 * ExecOnFailure=/usr/bin/foo
242 * fedora: make sshd and pam_loginuid work in nspawn containers
244 * fix utmp for console logins in containers
246 * Add pretty name for seats in logind
248 * nspawn wants dev_setup() for /dev/fd/ and friends?
250 * selinux: merge systemd selinux access controls (dwalsh)
252 * ConditionSecurity= should learn about IMA
254 * Auke: merge Auke's bootchart
258 * udev systemd unify:
259 - strpcpy(), strpcpyl(), strscpy(), strscpyl()
260 - utf8 validator code
261 - now() vs. now_usec()
263 * udev: remove network interface renaming, sleep and retry logic, we do
264 no support renaming of interfaces in the conflicting kernel
267 * udev: find a way to tell udev to not cancel firmware requests when running in initramfs
269 * udev: scsi_id -> sg3_utils -> kill scsi_id
271 * udev: add trigger --subsystem-match=usb/usb_device device
273 * allow configuration of console width/height in vconsole.conf
275 * cleanup syslog 'priority' vs. 'level' wording
277 * dbus upstream still refers to dbus.target and shouldn't
279 * 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
281 * support container_ttys=
283 * introduce mix of BindTo and Requisite
285 * journalctl: show multiline log messages sanely, expand tabs, and show all valid utf8 messages
287 * add DeleteSocketsOnStop=yes|no option to socket units
289 * journal: store euid in journal if it differs from uid
291 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
293 * journal: sanely deal with entries which are larger than the individual file size, but where the componets would fit
295 * add command to systemctl to plot dependency graph as tree (see rhbz 795365)
297 * make logind reserve tty9 or so for text logins, so that gdm never picks it up
299 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
301 * default unix qlen is too small (10). bump sysctl? add sockopt?
303 * Possibly, detect whether SysV init scripts can do reloading by looking for "echo Usage:" lines
305 * figure out whether we should leave dbus around during shutdown
307 * dbus: in fedora, make the machine a symlink to /etc/machine-id
309 * journald: reuse XZ context
311 * logind: add equivalent to sd_pid_get_owner_uid() to the D-Bus API
313 * journal: API for looking for retrieving "all values of this field"
315 * journal: deal nicely with byte-by-byte copied files, especially regards header
317 * journal: local deserializer of export mode, http server
319 * journal: message catalog
321 * document the exit codes when services fail before they are exec()ed
323 * systemctl journal command
325 * journalctl: --cursor support
327 * systemctl status: show coredumps
329 * save coredump in Windows/Mozilla minidump format
331 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
333 * clean up session cgroups that remain after logout (think sshd), but eventually run empty
335 * support "systemctl stop foobar@.service" to stop all units matching a certain template
337 * logind: allow showing logout dialog from system
339 * document that %% can be used to write % in a string that is specifier extended
341 * when an instanced service exits, remove its parent cgroup too if possible.
343 * if we can not get user quota for tmpfs, mount a separate tmpfs instance
344 for every user in /run/user/$USER with a configured maximum size
346 * default to actual 32bit PIDs, via /proc/sys/kernel/pid_max
348 * be able to specify a forced restart of service A where service B depends on, in case B
349 needs to be auto-respawned?
351 * Something is wrong with symlink handling of "autovt@.service" in "systemctl list-unit-files"
353 * when a bus name of a service disappears from the bus make sure to queue further activation requests
355 * something like ConditionExec= or ExecStartPre= without failure state
357 * tmpfiles: apply "x" on "D" too (see patch from William Douglas)
359 * don't set $HOME in services unless requested
361 * hide PAM/TCPWrap options in fragment parser when compile time disabled
363 * when we automatically restart a service, ensure we restart its rdeps, too.
365 * allow Type=simple with PIDFile=
366 https://bugzilla.redhat.com/show_bug.cgi?id=723942
368 * move PAM code into its own binary
370 * warn if the user stops a service but not its associated socket
372 * logind: spawn user@..service on login
374 * logind: non-local X11 server handling
376 * implement Register= switch in .socket units to enable registration
377 in Avahi, RPC and other socket registration services.
379 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
381 * readahead: use BTRFS_IOC_DEFRAG_RANGE instead of BTRFS_IOC_DEFRAG ioctl, with START_IO
383 * readahead: check whether a btrfs volume includes ssd by checking mount flag "ssd"
385 * support sd_notify() style notification when reload begins (RELOADING=1), reload is finished (READY=1), and add ReloadSignal= then to use in combination
387 * support sd_notify() style notification when shutting down, to make auto-exit bus services work (STOPPING=1)
389 * verify that the AF_UNIX sockets of a service in the fs still exist
390 when we start a service in order to avoid confusion when a user
391 assumes starting a service is enough to make it accessible
393 * Make it possible to set the keymap independently from the font on
394 the kernel cmdline. Right now setting one resets also the other.
396 * move nss-myhostname into systemd
398 * and a dbus call to generate target from current state
400 * drop /.readahead on bigger upgrades with yum
402 * add support for /bin/mount -s
404 * GC unreferenced jobs (such as .device jobs)
406 * when failing to start a service due to ratelimiting, try again later, if restart=always is set
408 * write blog stories about:
409 - enabling dbus services
411 - how to make changes to sysctl and sysfs attributes
413 - how to pass throw-away units to systemd, or dynamically change properties of existing units
414 - how to integrate cgconfig and suchlike with systemd
415 - resource control in systemd
417 - testing with Harald's awesome test kit
420 * allow port=0 in .socket units
422 * move readahead files into /var, look for them with .path units
424 * teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
426 * support systemd.mask= on the kernel command line.
428 * when key file cannot be found, read it from kbd in cryptsetup
430 * reuse mkdtemp namespace dirs in /tmp?
432 * recreate systemd's D-Bus private socket file on SIGUSR2
434 * Support --test based on current system state
436 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
438 * maybe introduce ExecRestartPre=
440 * configurable jitter for timer events
442 * timer events with system resume
444 * timer events on calendar time
446 * dot output for --test showing the 'initial transaction'
448 * calendar time support in timer, iCalendar semantics for the timer stuff (RFC2445)
449 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=99ee5315dac6211e972fa3f23bcc9a0343ff58c4
451 * implicitly import "defaults" settings file into all types
453 * writable cgroups dbus properties for live changes
455 * read config fragments for all units from /lib/systemd/system/foobar.service.d/ to override/extend specific settings
457 * port over to LISTEN_FDS/LISTEN_PID:
458 - rpcbind (/var/run/rpcbind.sock!) HAVEPATCH
462 - libvirtd (/var/run/libvirt/libvirt-sock-ro)
463 - bluetoothd (/var/run/sdp! @/org/bluez/audio!)
466 * auditd service files
468 * fingerprint.target, wireless.target, gps.target, netdevice.target
470 * io priority during initialization
472 * systemctl list-jobs - show dependencies
474 * add systemctl switch to dump transaction without executing it
476 * drop cap bounding set in readahead and other services
482 - natively watch for dbus-*.service symlinks (PENDING)
483 - allow specification of socket mode/umask when allocating DBusServer
484 - allow disabling of fd passing when connecting a AF_UNIX connection
485 - allow disabling of UID passing for AUTH EXTERNAL
486 - always pass cred data along each message
488 * fix alsa mixer restore to not print error when no config is stored
490 * gnome-shell python script/glxinfo/is-accelerated must die
492 * make cryptsetup lower --iter-time
494 * patch kernel for xattr support in /dev, /proc/, /sys and /sys/fs/cgroup?
496 * NTP: the kernel's 11-minutes-mode syncs the system time to the RTC, but only
497 in an ~30 minutes window. It does not adjust larger differences. Find a way
498 to tell the kernel, to always do a full time sync when the RTC is in UTC and
499 we are in 11-minutes-mode. When we trust the system time to NTP we also want
502 * kernel: add device_type = "fb", "fbcon" to class "graphics"
506 * look for close() vs. close_nointr() vs. close_nointr_nofail()
508 * check for strerror(r) instead of strerror(-r)
510 * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
512 * %m in printf() instead of strerror(errno);
516 * set_put(), hashmap_put() return values check. i.e. == 0 doesn't free()!
518 Scheduled for removal (or fixing):
520 * xxxOverridable dependencies
