systemd/TODO

F15:

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

* dep cycle basic → udev-retry → auditd → iptables → basic

* isolate multi-user.target doesn't start a getty@tty1 if we run it from graphical.target

* NFS, networkmanager ordering issue (PENDING)

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

* hook emergency.target into local-fs.target in some way as OnFailure with isolate

* drop SIGHUP handling from rsyslog.service upstream (PENDING)

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

* save/restore tool for SysV as requested by FPC (PENDING)

* bind mounts are ignored

* 0595f9a1c182a84581749823ef47c5f292e545f9 is borked, freezes shutdown

Features:

* optionally create watched directories in .path units

* consider services with no [Install] section and stored in /lib enabled by "systemctl is-enabled"

* 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

* 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

* 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

* support remote/ssh systemctl/systemadm, and local privileged access

* configurable jitter for timer events

* Support ProcessNeededForShutdown=true to allow stuff like mdmon
  to be killed very late after the rootfs is read only (?)

* 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    DONE
   - dbus     DONE
   - rsyslog  DONE
   - rpcbind (/var/run/rpcbind.sock!) DONE
   - cups     DONE

   - apache/samba
   - libvirtd (/var/run/libvirt/libvirt-sock-ro)
   - bluetoothd (/var/run/sdp! @/org/bluez/audio!)
   - distccd

* fingerprint.target, wireless.target, gps.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

* accountsservice is borked

* auditd service files

* add systemctl switch to dump transaction without executing it

* suspend, resume

* readahead: btrfs/LVM SSD detection

* add separate man page for [Install] settings

* only add quotacheck deps to .mount units which mention grpquota/usrquota in the mount flags

* systemctl condrestart should return 0 if service isn't running

* 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 wech

* 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

device: do not merge devices Don't try to merge devices that have been created via dependencies when they appear in the system and can be recognized as the same. Instead, simply continue to maintain them independently of each other, however with the same state cycle. Why? Because otherwise we'd have a hard time to seperate the dependencies after the devices are unplugged again and we hence cannot be sure anymore that next time the device is plugged in it will carry the same names. Example: if one depndency refers to dev-sda.device and another one to dev-by-id-xxxyyy.device we only learn at time of plug in of the device that it is actually the same device that was ment. In the moment the device is unplugged again we won't know anymore their relation to each other and the next time the harddisk is plugged it might even appear as dev-by-id-xxxyyy.device and dev-sdb.service. To ensure the dependencies continue to have the meaning they were intended to have let's hence keep the .device objects seperate all the time, even when they are plugged in. This patch also introduces a new Following= property which points from the various .device units of a specific device to the main .device unit for it. This can be used by the client side to figure out the relation of the .device units to each other and even filter units from display. 2010-07-21 02:33:19 +08:00
