mount: make device timeout configurable

[thirdparty/systemd.git] / TODO

F15:

* swap units that are activated by one name but shown in the kernel under another are semi-broken

* NFS, networkmanager ordering issue (PENDING)

* NM should pull in network.target (PENDING)
  https://bugzilla.redhat.com/show_bug.cgi?id=692008

* bluetooth should be possible to disable (PENDING)

* add fstab fields to add wait timeouts, change Wants to Requires by local-fs.target

* bind mounts are ignored
  https://bugzilla.redhat.com/show_bug.cgi?id=682662

* 0595f9a1c182a84581749823ef47c5f292e545f9 is borked, freezes shutdown
    (path: after installing inotify watches, recheck file again to fix race)

* get writev() /dev/kmsg support into the F15 kernel
    https://lkml.org/lkml/2011/4/6/473
  patched merged into -mm

* fix sd_is_socket() invocation in dbus

* fix default timeout values mentioned in man page

* New CK release, with sysinit.target dropping and TTY loop

* New Avahi package, enable it by default

* don't trim empty cgroups
  https://bugzilla.redhat.com/show_bug.cgi?id=678555

Features:

* use pivot_root on shutdown so that we can unmount the root directory.

* fix alsa mixer restore to not print error when no config is stored

* show enablement status in systemctl status

* write blog stories about:
  - enabling dbus services
  - status update
  - you are a distro: why switch?

* allow port = 0 in .socket units

* rename systemd-logger to systemd-stdio-syslog-bridge

* introduce /usr/lib/binfmt.d/, /usr/lib/tmpfiles.d/

* take BSD file lock on tty devices when using them?

* avoid any flag files, or readahead files in /, we need to support r/o /
  or / on tmpfs like Android setups.

* move readahead files into /var, look for them with .path units

* teach dbus to activate all services it finds in /etc/systemd/services/org-*.service

* get process transport into dbus for systemctl -P/-H

* document default dependencies

* support systemd.whitelist=/systemd.blacklist= on the kernel command
  line.

* Find a way to replace /var/run, /var/lock directories with
  symlinks during an RPM package upgrade (filesystem.rpm or systemd.rpm).
  (lua code to create symlinks right away for new installations is in filesytem.rpm now)
  We soon want to get rid of var-run.mount var-lock.mount units:
    if mountpoint /run ; then
          umount /var/run || :
    else
          mount --move /var/run /run || mount --bind /var/run /run
    fi
    mv /var/run /var/.run.save
    ln -s /run /var/run
    echo "R /var/.run.save" > /etc/tmpfiles.d/remove-run-save.conf

* when key file cannot be found, read it from kbd in cryptsetup

* add switch to systemctl to show enabled but not running services. Or
  another switch that shows service that have been running since
  booting but aren't running anymore.

* reuse mkdtemp namespace dirs in /tmp?

* recreate systemd's D-Bus private socket file on SIGUSR2

* be more specific what failed:
    ...
    Unmounting file systems.
    Not all file systems unmounted, 1 left.
    Disabling swaps.
    Detaching loop devices.
    Detaching DM devices.
    Cannot finalize remaining file systems and devices, trying to kill remaining processes.
    Unmounting file systems.
    Not all file systems unmounted, 1 left.
    Cannot finalize remaining file systems and devices, giving up.
    ...

* check for compiled-in, but not active selinux, and don't print any warnings
  about policy loading. Probably check for available selinux in /proc/filesystems,
  and check for active selinux with getcon_raw() == "kernel"

* Support --test based on current system state

* systemctl enable as D-Bus call

* consider services with any kind of link in /etc/systemd/system enabled

* show failure error string in "systemctl status"

* make sure timeouts are applied to Type=oneshot services.

* Maybe implement "systemctl mask" and "systemctl unmask", but not
  document it? When doing that add switch to make this temporary by
  placing mask links in /dev.

* detect LXC environment

* invoke vhangup() before and after invoking getty
    http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=3c95c985fa91ecf6a0e29622bbdd13dcfc5ce9f1

* support "auto" and "comment=systemd.automount" at the same time for an fstab entry

* Maybe store in unit files whether a service should be enabled by default on package installation
  (belongs into a distro pattern though, not in an upstream package's service file)

* perhaps add "systemctl reenable" as combination of "systemctl disable" and "systemctl enable"

* need a way to apply mount options of api vfs from systemd unit files
  (or some other modern source?) instead of fstab?

* maybe introduce ExecRestartPre=

* figure out what happened to bluez patch

* Patch systemd-fsck to use -C and pass console fd to it

* configurable jitter for timer events

* Support ProcessNeededForShutdown=true to allow stuff like mdmon to
  be killed very late after the rootfs is read only? If implement pass
  this to shutdown binary via command line argument.

* Integrate "mdadm --wait-clean". Maybe just let SIGTERM to mdmon trigger the
  needed action

* dot output for --test showing the 'initial transaction'

* calendar time support in timer, iCalendar semantics for the timer stuff (RFC2445)
  - check timerfd() patch: http://lkml.org/lkml/2010/11/23/290

* systemd --user
  - get PR_SET_ANCHOR merged: http://lkml.org/lkml/2010/2/2/165

* add VT tracking:
  - provide CK functionality
  - start getty only when actual vt switch happens (same model as
    socket on-demand activation). allocate the next free tty and
    start a getty there. this way, pressing alt-f[1-12] will switch
    through running X and getty sessions, and any unallocated
    activated tty will start a new getty. the hardcoding of
    getty[1-6] will entirely go away.

* implicitly import "defaults" settings file into all types

* port over to LISTEN_FDS/LISTEN_PID:
   - uuidd    HAVEPATCH
   - rpcbind (/var/run/rpcbind.sock!) HAVEPATCH
   - cups     HAVEPATCH
   - postfix, saslauthd
   - apache/samba
   - libvirtd (/var/run/libvirt/libvirt-sock-ro)
   - bluetoothd (/var/run/sdp! @/org/bluez/audio!)
   - distccd

* fingerprint.target, wireless.target, gps.target, netdevice.target

* set_put(), hashmap_put() return values check. i.e. == 0 doesn't free()!

* io priority during initialization

* if a service fails too often, make the service enter failed mode, and the socket, too.

* systemctl list-jobs - show dependencies

* auditd service files

* add systemctl switch to dump transaction without executing it

* suspend, resume support?

* readahead: btrfs/LVM SSD detection

* add separate man page for [Install] settings

* allow runtime changing of log level and target

External:

* udisks should not use udisks-part-id, instead use blkid. also not probe /dev/loopxxx

* snd-seq should go, https://bugzilla.redhat.com/show_bug.cgi?id=676095

* gnome-shell python script/glxinfo/is-accelerated must die

* make cryptsetup lower --iter-time

* patch kernel for xattr support in /dev, /proc/, /sys and /sys/fs/cgroup.

* patch kernel for cpu feature modalias for autoloading aes/kvm/...
    http://git.kernel.org/?p=linux/kernel/git/ak/linux-misc-2.6.git;a=shortlog;h=refs/heads/cpuid-match
  (Rafael J. Wysocki's sysdev rework is on the way. After that CPUs can be exported a proper bus.)

* procps, psmisc, sysvinit-tools, hostname → util-linux-ng

Regularly:

* look for close() vs. close_nointr() vs. close_nointr_nofail()

* check for strerror(r) instead of strerror(-r)

* Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel

* %m in printf() instead of strerror();

* pahole

* CFLAGS="-Wl,--gc-sections -Wl,--print-gc-sections -ffunction-sections -fdata-sections"
