TODO

   1 Bugfixes:
   2 * check systemd-tmpfiles for selinux context hookup for mknod(), symlink() and similar
   3
   4 * swap units that are activated by one name but shown in the kernel under another are semi-broken
   5
   6 * make anaconda write timeout=0 for encrypted devices
   7
   8 * Dangling symlinks of .automount unit files in .wants/ directories, set up
   9   automount points even when the original .automount file did not exist
  10   anymore. Only the .mount unit was still around.
  11
  12 * make polkit checks async
  13
  14 * properly handle .mount unit state tracking when two mount points are stacked one on top of another on the exact same mount point.
  15
  16 F18:
  17
  18 * Retest multi-seat
  19
  20 Features:
  21
  22 * deal with sendmail/postfix exclusivity
  23
  24 * systemctl enable: improve the success messages
  25
  26 * systemctl enable: fail if target to alias into doesn't exist? maybe show how many units are enabled afterwards?
  27
  28 * on shutdown: move utmp, wall, audit logic all into PID 1 itsel
  29
  30 * add "provisioning" instructions to setup an empty /etc + /var
  31     - used to setup a new container from a shared /usr
  32     - superset of tmpfiles model
  33     - instructions shipped by packages and stored in /usr/lib/
  34     - compose /etc/passwd and /etc/group, copy files
  35     - able to create uid + gid used by packages, for file ownership
  36
  37 * make repeated alt-ctrl-del presses printing a dump, or even force a reboot without
  38   waiting for the timeout
  39
  40 * make sure that the journal output from the initrd is always merged into the journalctl output even if -m is not passed.
  41
  42 * add time seeks to journalctl
  43
  44 * high level net_prio setting in execution context
  45
  46 * Introduce journalctl -b <nr> to show journal messages of a previous boot
  47
  48 * systemctl should be able to show log messages from certain privileged 3rd party daemons such as setroubleshoot
  49
  50 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
  51
  52 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab isn't
  53
  54 * WorkingDirectory: support env var replacements like in ExecStart= so that people can use $HOME
  55
  56 * refuse boot if /etc/machine-id is not useful
  57
  58 * nspawn: consider changing users for -u with su, so that NSS resolving works correctly
  59
  60 * nspawn: implement personality changes a la linux32(8)
  61
  62 * nspawn: reset all aux groups
  63
  64 * cryptsetup-generator: warn if the password files are world-readable
  65
  66 * cryptsetup-generator: add RequiresMountsFor= to cryptseup service files referencing a file, similar for devices
  67
  68 * cryptsetup-generator: allow specification of passwords in crypttab itself
  69
  70 * document that deps in [Unit] sections ignore Alias= fileds in
  71   [Install] units of other units, unless those units are disabled
  72
  73 * need to update LGPL2.1 text to newest version (with updated FSF address)
  74
  75 * allow users from "wheel" to start/stop services
  76
  77 * systemctl: when powering down/suspending check for inhibitors, and warn.
  78
  79 * instantiated [Install] for target units
  80   https://bugs.freedesktop.org/show_bug.cgi?id=54377
  81
  82 * support *static* (/run) hibernate inhibitors. All rpm -i actions should completely prevent any
  83   sort of hibernate action until the next reboot. If the kernel or any other base tool is replaced
  84   by rpm, the resume path might fail, the for resume needed kernel might even be uninstalled, and
  85   the whole situation leads directly to data loss.
  86
  87 * move debug shell to tty6 and make sure this doesn't break the gettys on tty6
  88
  89 * move cryptsetup key caching into kernel keyctl?
  90   https://bugs.freedesktop.org/show_bug.cgi?id=54982
  91
  92 * make nspawn work without terminal
  93
  94 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
  95   https://bugs.freedesktop.org/show_bug.cgi?id=54712
  96
  97 * after deserializing sockets in socket.c we should reapply sockopts and things
  98
  99 * does vasprintf advance the struct vaargs? http://pastie.org/pastes/4712773/text
 100
 101 * do shutdown audit/utmp msgs inside of PID 1, get rid of systemd-update-utmp-runlevel
 102
 103 * make timer units go away after they elapsed
 104
 105 * http://lists.freedesktop.org/archives/systemd-devel/2012-September/006502.html
 106
 107 * come up with a nice way to write queue/read_ahead_kb for a block device without interfering with readahead
 108
 109 * journald: add kernel cmdline option to disable ratelimiting for debug purposes
 110
 111 * move PID 1 segfaults to /var/lib/systemd/coredump?
 112
 113 * Document word splitting syntax for ExecStart= and friends
 114
 115 * when writing journal entries order field items by their address to improve speed on rotating media
 116
 117 * create /sbin/init symlinks from the build system
 118
 119 * Query Paul Moore about relabelling socket fds while they are open
 120
 121 * move keymaps to /usr/lib/... rather than /usr/lib/udev/...
 122
 123 * journald: check whether it is OK if the client can still modify delivered journal entries
 124
 125 * json: use jensson
 126
 127 * json: properly serialize multiple fields with the same name per entry
 128
 129 * journal live copy, based on libneon (client) and libmicrohttpd
 130
 131 * document in wiki json serialization
 132
 133 * system-wide seccomp filter
 134
 135 * ability to pass fds into systemd
 136
 137 * system.conf should have controls for cgroups
 138
 139 * bind mount read-only the cgroup tree higher than than nspawn
 140
 141 * currently system services appear not to generate core dumps...
 142
 143 * wall messages for shutdown should move to logind
 144
 145 * allow writing multiple conditions in unit files on one line
 146
 147 * 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
 148
 149 * explore multiple service instances per listening socket idea
 150
 151 * 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.
 152
 153 * maybe make systemd-detect-virt suid? or use fscaps?
 154
 155 * shutdown: don't read-only mount anything when running in container
 156
 157 * nspawn: --read-only is not applied recursively to submounts
 158
 159 * MountFlags=shared acts as MountFlags=slave right now.
 160
 161 * ReadOnlyDirectories= is not applied recursively to submounts
 162
 163 * drop PID 1 reloading, only do reexecing (difficult: Reload()
 164   currently is properly synchronous, Reexec() is weird, because we
 165   can't delay the response properly until we are back, so instead of
 166   being properly synchronous we just keep open the fd and close it
 167   when done. That means clients don't get a succesful method reply,
 168   but much rather a disconnect on success.
 169
 170 * document that service reload may be implemented as service reexec
 171
 172 * remember which condition failed for services, not just the fact that something failed
 173
 174 * use opterr = 0 for all getopt tools
 175
 176 * properly handle loop back mounts via fstab, especially regards to fsck/passno
 177
 178 * allow services with no ExecStart= but with an ExecStop=
 179
 180 * add proper journal support to "systemctl --user status ..."
 181
 182 * add _SYSTEMD_USER_UNIT= field to journal entries
 183
 184 * dracut-shutdown needs to be ordered before unmounting /boot
 185
 186 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
 187
 188 * 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.
 189
 190 * rename "userspace" to "core-os"
 191
 192 * systemctl: "Journal has been rotated since unit was started." message is misleading
 193
 194 * syscall filter: add knowledge about compat syscalls
 195
 196 * syscall filter: don't enforce no new privs?
 197
 198 * syscall filter: option to return EPERM rather than SIGSYS?
 199
 200 * syscall filter: port to libseccomp
 201
 202 * logind: wakelock/opportunistic suspend support
 203
 204 * systemd-analyze post-boot is broken for initrd
 205
 206 * man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
 207
 208 * .device aliases need to be implemented with the "following" logic, probably.
 209
 210 * refuse taking lower-case variable names in sd_journal_send() and friends.
 211
 212 * load-fragment: when loading a unit file via a chain of symlinks
 213   verify that it isn't masked via any of the names traversed.
 214
 215 * journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
 216
 217 * Document:
 218         - PID 1 D-Bus API
 219
 220 * introduce Type=pid-file
 221
 222 * systemctl list-unit-files appears to be broken for symlinked units in /usr/lib
 223
 224 * maybe allow services with ExecStop= set, but no ExecStart=?
 225
 226 * efi: implement /forcefsck as uefi variables thus not requiring file system altering to trigger a file system check
 227
 228 * efi: honour language efi variables for default language selection
 229
 230 * efi: honour timezone efi variables for default timezone selection
 231
 232 * efi: automatically mount EFI partition to /boot if no such entry exists in /etc/fstab and /boot is empty
 233   gummiboot exports the EFI system partion (ESP) device:
 234   /sys/firmware/efi/vars/LoaderDeviceIdentifier-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
 235   Acpi(PNP0A03,0)/Pci(1F|2)/?/HD(Part1,Sig1FCBC57F-4BFC-4C2B-91A3-9C84FBCD9AF1)
 236   '/' is the separator for the device path list
 237   HD(Part1,Sig1FCBC57F-4BFC-4C2B-91A3-9C84FBCD9AF1) contains the GPT UUID of the ESP
 238
 239 * read the bootloader performance data (raw TSC) in systemd-analyze
 240   /sys/firmware/efi/vars/LoaderTicksExec-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
 241   19066159288
 242   /sys/firmware/efi/vars/LoaderTicksInit-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
 243   17442940316
 244   /sys/firmware/efi/vars/LoaderTicksStartMenu-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f/data
 245   (only set if the menu was active)
 246
 247 * change Requires=basic.target to RequisiteOverride=basic.target
 248
 249 * support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
 250
 251 * systemctl: when stopping a service which has triggres and warning about it actually check the TriggeredBy= deps fields
 252
 253 * nspawn: make use of device cgroup contrller by default
 254
 255 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
 256
 257 * when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
 258
 259 * readahead: when bumping /sys readahead variable save mtime and compare later to detect changes
 260
 261 * (attempt to) make Debianites happy:
 262         - implement .d/ auto includes for unit files
 263         - add syntax to reset ExecStart= lists (and similar)
 264
 265 * move passno parsing to fstab generator
 266
 267 * improve !/proc/*/loginuid situation: make /proc/*/loginuid less dependent on CONFIG_AUDIT,
 268   or use the users cgroup information when /proc/*/loginuid is not available.
 269
 270 * pam_systemd: try to get old session id from cgroup, if audit sessionid cannot be determined
 271
 272 * pam: when leaving a session explicitly exclude the ReleaseSession() caller process from the killing spree
 273
 274 * maybe introduce ~/.config/locale.conf and apply it within PAM
 275
 276 * readahead: make use of EXT4_IOC_MOVE_EXT, as used by http://e4rat.sourceforge.net/
 277
 278 * automount: implement expire
 279
 280 * logind: auto-suspend, auto-shutdown:
 281         IdleAction=(none|suspend|opportunistic|hibernate|poweroff)
 282         IdleActionDelay=...
 283         SessionIdleMode=(explicit|ignore|login)
 284         ForceShutdown=(yes|no)
 285
 286 * services which create their own subcgroups break cgroup-empty notification (needs to be fixed in the kernel)

 309   - now() vs. now_usec()
 310

 319 * udev: add trigger --subsystem-match=usb/usb_device device
 320
 321 * allow configuration of console width/height in vconsole.conf
 322
 323 * cleanup syslog 'priority' vs. 'level' wording
 324
 325 * dbus upstream still refers to dbus.target and shouldn't
 326
 327 * 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
 328
 329 * support container_ttys=
 330
 331 * introduce mix of BindTo and Requisite
 332
 333 * journalctl: show multiline log messages sanely, expand tabs, and show all valid utf8 messages

 335 * add DeleteSocketsOnStop=yes|no option to socket units
 336
 337 * journal: store euid in journal if it differs from uid
 338
 339 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
 340
 341 * journal: sanely deal with entries which are larger than the individual file size, but where the componets would fit
 342
 343 * add command to systemctl to plot dependency graph as tree (see rhbz 795365)
 344
 345 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
 346
 347 * default unix qlen is too small (10). bump sysctl? add sockopt?
 348
 349 * Possibly, detect whether SysV init scripts can do reloading by looking for "echo Usage:" lines
 350
 351 * figure out whether we should leave dbus around during shutdown
 352
 353 * dbus: in fedora, make the machine a symlink to /etc/machine-id
 354
 355 * dbus: move dbus to early boot
 356
 357 * journald: reuse XZ context
 358
 359 * logind: add equivalent to sd_pid_get_owner_uid() to the D-Bus API
 360
 361 * journal: API for looking for retrieving "all values of this field"

 390
 391 * be able to specify a forced restart of service A where service B depends on, in case B
 392   needs to be auto-respawned?
 393
 394 * Something is wrong with symlink handling of "autovt@.service" in "systemctl list-unit-files"
 395
 396 * when a bus name of a service disappears from the bus make sure to queue further activation requests
 397
 398 * something like ConditionExec= or ExecStartPre= without failure state
 399
 400 * tmpfiles: apply "x" on "D" too (see patch from William Douglas)
 401
 402 * don't set $HOME in services unless requested

 425
 426 * readahead: check whether a btrfs volume includes ssd by checking mount flag "ssd"
 427
 428 * support sd_notify() style notification when reload begins (RELOADING=1), reload is finished (READY=1), and add ReloadSignal= then to use in combination
 429
 430 * support sd_notify() style notification when shutting down, to make auto-exit bus services work (STOPPING=1)
 431
 432 * verify that the AF_UNIX sockets of a service in the fs still exist
 433   when we start a service in order to avoid confusion when a user
 434   assumes starting a service is enough to make it accessible
 435
 436 * Make it possible to set the keymap independently from the font on
 437   the kernel cmdline. Right now setting one resets also the other.
 438
 439 * move nss-myhostname into systemd
 440
 441 * and a dbus call to generate target from current state
 442
 443 * drop /.readahead on bigger upgrades with yum
 444
 445 * add support for /bin/mount -s
 446

 464
 465 * teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
 466
 467 * support systemd.mask= on the kernel command line.
 468
 469 * when key file cannot be found, read it from kbd in cryptsetup

 474
 475 * Support --test based on current system state
 476
 477 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
 478
 479 * maybe introduce ExecRestartPre=
 480
 481 * configurable jitter for timer events
 482
 483 * timer events with system resume
 484
 485 * dot output for --test showing the 'initial transaction'
 486
 487 * calendar time support in timer:
 488     https://docs.google.com/document/pub?id=1bAMyFAjWLpzR3GTDYdgj5FWRMxoZiWw5zmUHEtvdHKA

 491
 492 * writable cgroups dbus properties for live changes
 493
 494 * read config fragments for all units from /lib/systemd/system/foobar.service.d/ to override/extend specific settings
 495
 496 * port over to LISTEN_FDS/LISTEN_PID:
 497    - rpcbind (/var/run/rpcbind.sock!) HAVEPATCH
 498    - cups     HAVEPATCH
 499    - postfix, saslauthd
 500    - apache/samba
 501    - libvirtd (/var/run/libvirt/libvirt-sock-ro)
 502    - bluetoothd (/var/run/sdp! @/org/bluez/audio!)
 503    - distccd
 504
 505 * fingerprint.target, wireless.target, gps.target, netdevice.target
 506
 507 * io priority during initialization
 508
 509 * systemctl list-jobs - show dependencies
 510
 511 * add systemctl switch to dump transaction without executing it
 512
 513 * drop cap bounding set in readahead and other services
 514
 515 External:
 516

 518    - dbus --user
 519    - natively watch for dbus-*.service symlinks (PENDING)
 520    - allow specification of socket mode/umask when allocating DBusServer
 521    - allow disabling of fd passing when connecting a AF_UNIX connection
 522    - allow disabling of UID passing for AUTH EXTERNAL
 523    - always pass cred data along each message
 524
 525 * fix alsa mixer restore to not print error when no config is stored
 526

 528
 529 * make cryptsetup lower --iter-time
 530
 531 * patch kernel for xattr support in /dev, /proc/, /sys and /sys/fs/cgroup?
 532
 533 * NTP: the kernel's 11-minutes-mode syncs the system time to the RTC, but only
 534   in an ~30 minutes window. It does not adjust larger differences. Find a way
 535   to tell the kernel, to always do a full time sync when the RTC is in UTC and
 536   we are in 11-minutes-mode. When we trust the system time to NTP we also want
 537   the RTC to sync up.
 538
 539 * kernel: add device_type = "fb", "fbcon" to class "graphics"
 540
 541 Regularly:
 542
 543 * look for close() vs. close_nointr() vs. close_nointr_nofail()
 544
 545 * check for strerror(r) instead of strerror(-r)
 546
 547 * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
 548
 549 * %m in printf() instead of strerror(errno);
 550
 551 * pahole
 552
 553 * set_put(), hashmap_put() return values check. i.e. == 0 doesn't free()!
 554
 555 * use secure_getenv() instead of getenv() where appropriate
 556
 557 Scheduled for removal or fixing:
 558
 559 * xxxOverridable dependencies (probably: fix)
 560
 561 * support for early-boot SysV services (definitely: remove)
