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
(path: after installing inotify watches, recheck file again to fix race)
* capability_bounding_set_drop not used
* rework syslog.service being up logic in PID 1
* rsyslog.service should hook itself into syslog.target?
* syslog.target should be pulled in by multi-user.target?
* pull in .service from meta .targers AND vice versa too. i.e. syslog.target ←→ rsyslog.service, rpcbind similarly
* drop Names= option? Symlinks only should be used. We don't want to need to read all service files.
Features:
* don't strip facility from kmsg log messages as soon as that is possible.

* recreate systemd'd 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"
* optionally create watched directories in .path units
* Support --test based on current system state
* 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.
Consider moving the actual fs operations into systemd behind a D-Bus
interface, to make namespaces/containers/remote connections work properly.
* 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
(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
* 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 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
* 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 support?
* 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 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"
