Bugfixes:
* remove MS_SHARED from src/core/execute.c and src/test/test-ns.c. They are always combined
with MS_REMOUNT, which currently does nothing in the kernel, but might which fail in the
future; https://bugzilla.redhat.com/show_bug.cgi?id=813563
* check systemd-tmpfiles for selinux context hookup for mknod(), symlink() and similar
* swap units that are activated by one name but shown in the kernel under another are semi-broken
* make anaconda write timeout=0 for encrypted devices
* Dangling symlinks of .automount unit files in .wants/ directories, set up
automount points even when the original .automount file did not exist
anymore. Only the .mount unit was still around.
* make polkit checks async
* properly handle .mount unit state tracking when two mount points are stacked one on top of another on the exact same mount point.
* we pull src/core/manager.h into src/shared/src/shared/path-lookup.c which is the wrong direction
rename enum "ManagerRunningAs" to "SystemdRunningAs" and move it to shared/
* crash happens when running a service as forking and then changing it to simple and reloading.

Features:
* compile libsystemd-journal statically into journalctl so that we can share util.c and suchlike
* replace BindTo= by BindsTo=, but keep old name for compat
* switch-root: sockets need relabelling
* switch-root: handle journald restart
* segfault in journalctl during /var migration
* systemd-analyze post-boot is broken for initrd
* man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
* journalctl should complain if run with uid != 0 and no persistant logs exist
* .device aliases need to be implemented with the "following" logic, probably.
* refuse taking lower-case variable names in sd_journal_send() and friends.
* when running as user instance: implicitly default to WorkingDirectory=$HOME for all services.
* Merge KillUnit()'s mode and who params into one
* load-fragment: when loading a unit file via a chain of symlinks
verify that it isn't masked via any of the names traversed.
* journald: _BOOT_ID triggers too many collisions.
* journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
* reexec journald across initrd transition
* nspawn: bind mount /var/log/journal from the host
* The current Storage=auto logic is borked, since people cannot mount
/var/log/journal via NFS since the mount point has to exist and we
already take that as signal to store our stuff there.
* Document:
- PID 1 D-Bus API
- Journal C API manual pages
- scheduled shutdown API
* wiki: document logind's PreparingForShutdown, PreparingForSleep
* introduce Type=pid-file
* systemctl list-unit-files appears to be broken for symlinked units in /usr/lib
* maybe allow services with ExecStop= set, but no ExecStart=?
* efi: implement /forcefsck as uefi variables thus not requiring file system altering to trigger a file system check
* efi: honour language efi variables for default language selection
* efi: honour timezone efi variables for default timezone selection
* efi: automatically mount EFI partition to /boot if no such entry exists in /boot
* new dependency type to "group" services in a target
* change Requires=basic.target to RequisiteOverride=basic.target
* exclude processes marked with argv[0][0]=@ from the normal service killing too
* support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
* systemctl: when stopping a service which has triggres and warning about it actually check the TriggeredBy= deps fields
* journal: hook up with EFI firmware log, new kmsg logic
* handle C-A-Del in logind, like the power/suspend buttons?
* nspawn: make use of device cgroup contrller by default
* journalctl /dev/sda, journalctl --device=b12:8 (--device=n12, --device=+usb:1-1)
* make use of /sys/power/wake_lock in inhibitors
* drop accountsservice's StandardOutput=syslog and Type=dbus fields
* make sure show-logs checks for utf8 validity, not ascii validity
* when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
* readahead: when bumping /sys readahead variable save mtime and compare later to detect changes
* (attempt to) make Debianites happy:
- implement .d/ auto includes for unit files
- add syntax to reset ExecStart= lists (and similar)
* manipulate CPU governor during boot, set it to performance
* steal SBF management from the kernel
* delay journal /var writeout to after boot if SBF is clean
* move passno parsing to fstab generator
* improve !/proc/*/loginuid situation: make /proc/*/loginuid less dependent on CONFIG_AUDIT,
or use the users cgroup information when /proc/*/loginuid is not available.
* pam_systemd: try to get old session id from cgroup, if audit sessionid cannot be determined
* pam: when leaving a session explicitly exclude the ReleaseSession() caller process from the killing spree
* maybe introduce ~/.config/locale.conf and apply it within PAM
* readahead: make use of EXT4_IOC_MOVE_EXT, as used by http://e4rat.sourceforge.net/
* automount: implement expire
* logind: auto-suspend, auto-shutdown:
IdleAction=(none|suspend|opportunistic|hibernate|poweroff)
IdleActionDelay=...
SessionIdleMode=(explicit|ignore|login)
ForceShutdown=(yes|no)
* services which create their own subcgroups break cgroup-empty notification (needs to be fixed in the kernel)

* ExecOnFailure=/usr/bin/foo
* fedora: make sshd and pam_loginuid work in nspawn containers
* fix utmp for console logins in containers
* Add pretty name for seats in logind
* nspawn wants dev_setup() for /dev/fd/ and friends?
* selinux: merge systemd selinux access controls (dwalsh)
* ConditionSecurity= should learn about IMA
* Auke: merge Auke's bootchart
* udev: move to LGPL
* udev systemd unify:
- strpcpy(), strpcpyl(), strscpy(), strscpyl()
- utf8 validator code
- now() vs. now_usec()
* udev: remove network interface renaming, sleep and retry logic, we do
no support renaming of interfaces in the conflicting kernel
namespace
* udev: find a way to tell udev to not cancel firmware requests when running in initramfs
* udev: scsi_id -> sg3_utils -> kill scsi_id
* udev: add trigger --subsystem-match=usb/usb_device device
* allow configuration of console width/height in vconsole.conf
* cleanup syslog 'priority' vs. 'level' wording
* journal: if mmap() fails for mapping window try to unmap a a few older maps
* dbus upstream still refers to dbus.target and shouldn't
* 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
* support container_ttys=
* introduce mix of BindTo and Requisite
* journalctl: show multiline log messages sanely, expand tabs, and show all valid utf8 messages
* add DeleteSocketsOnStop=yes|no option to socket units
* journal: store euid in journal if it differs from uid
* There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
* journal: sanely deal with entries which are larger than the individual file size, but where the componets would fit
* add command to systemctl to plot dependency graph as tree (see rhbz 795365)
* make logind reserve tty9 or so for text logins, so that gdm never picks it up
* add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
* default unix qlen is too small (10). bump sysctl? add sockopt?
* Possibly, detect whether SysV init scripts can do reloading by looking for "echo Usage:" lines
* figure out whether we should leave dbus around during shutdown
* dbus: in fedora, make the machine a symlink to /etc/machine-id

* save coredump in Windows/Mozilla minidump format
* support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
* clean up session cgroups that remain after logout (think sshd), but eventually run empty
* support "systemctl stop foobar@.service" to stop all units matching a certain template
* logind: allow showing logout dialog from system
* document that %% can be used to write % in a string that is specifier extended
* when an instanced service exits, remove its parent cgroup too if possible.
* if we can not get user quota for tmpfs, mount a separate tmpfs instance
for every user in /run/user/$USER with a configured maximum size
* default to actual 32bit PIDs, via /proc/sys/kernel/pid_max
* add an option to make mounts private/shareable and so on, enable this for root by default
* be able to specify a forced restart of service A where service B depends on, in case B
needs to be auto-respawned?
* Something is wrong with symlink handling of "autovt@.service" in "systemctl list-unit-files"
* when a bus name of a service disappears from the bus make sure to queue further activation requests
* something like ConditionExec= or ExecStartPre= without failure state
* tmpfiles: apply "x" on "D" too (see patch from William Douglas)
* don't set $HOME in services unless requested
* hide PAM/TCPWrap options in fragment parser when compile time disabled
* when we automatically restart a service, ensure we restart its rdeps, too.
* allow Type=simple with PIDFile=

in Avahi, RPC and other socket registration services.
* make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
* readahead: use BTRFS_IOC_DEFRAG_RANGE instead of BTRFS_IOC_DEFRAG ioctl, with START_IO
* readahead: check whether a btrfs volume includes ssd by checking mount flag "ssd"
* support sd_notify() style notification when reload begins (RELOADING=1), reload is finished (READY=1), and add ReloadSignal= then to use in combination
* support sd_notify() style notification when shutting down, to make auto-exit bus services work (STOPPING=1)
* verify that the AF_UNIX sockets of a service in the fs still exist
when we start a service in order to avoid confusion when a user
assumes starting a service is enough to make it accessible

* and a dbus call to generate target from current state
* drop /.readahead on bigger upgrades with yum
* add support for /bin/mount -s
* GC unreferenced jobs (such as .device jobs)
* when failing to start a service due to ratelimiting, try again later, if restart=always is set
* write blog stories about:
- enabling dbus services
- status update
- how to make changes to sysctl and sysfs attributes
- remote access
- how to pass throw-away units to systemd, or dynamically change properties of existing units
- how to integrate cgconfig and suchlike with systemd
- resource control in systemd
- inhibiting
- testing with Harald's awesome test kit
* allow port=0 in .socket units

* recreate systemd's D-Bus private socket file on SIGUSR2
* Support --test based on current system state
* investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
* maybe introduce ExecRestartPre=
* configurable jitter for timer events
* timer events with system resume
* timer events on calendar time
* dot output for --test showing the 'initial transaction'
* calendar time support in timer, iCalendar semantics for the timer stuff (RFC2445)

* implicitly import "defaults" settings file into all types
* exec settings override
* writable cgroups dbus properties for live changes
* read config fragments for all units from /lib/systemd/system/foobar.service.d/ to override/extend specific settings
* port over to LISTEN_FDS/LISTEN_PID:
- 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
* auditd service files
* fingerprint.target, wireless.target, gps.target, netdevice.target
* io priority during initialization
* systemctl list-jobs - show dependencies
* add systemctl switch to dump transaction without executing it
* drop cap bounding set in readahead and other services
External:
* dbus:
- dbus --user
- natively watch for dbus-*.service symlinks (PENDING)
- allow specification of socket mode/umask when allocating DBusServer
- allow disabling of fd passing when connecting a AF_UNIX connection
- allow disabling of UID passing for AUTH EXTERNAL
- always pass cred data along each message
* fix alsa mixer restore to not print error when no config is stored
* 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?
* NTP: the kernel's 11-minutes-mode syncs the system time to the RTC, but only
in an ~30 minutes window. It does not adjust larger differences. Find a way
to tell the kernel, to always do a full time sync when the RTC is in UTC and
we are in 11-minutes-mode. When we trust the system time to NTP we also want
the RTC to sync up.
* kernel: add device_type = "fb", "fbcon" to class "graphics"
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
* set_put(), hashmap_put() return values check. i.e. == 0 doesn't free()!
Scheduled for removal (or fixing):
* xxxOverridable dependencies
* journald.conf: ImportKernel=
* prefdm.service
