Previously, if X allocated all 6 TTYs (for multi-session for example) no getty would be available anymore to guarantee console-based logins. With the new ReserveVT= switch in logind.conf we can now choose one VT (6 by default) that will always be subject to autovt-style activation, i.e. we'll always have a getty on TTY6, and X will never take possession of it.

Bugfixes:
|
|
* always open() tty6 to keep X from using it; move debug shell to tty6
|
|
|
|
* there is nothing to warn about here :)
|

$ systemctl stop systemd-udevd.service systemd-udevd-kernel.socket systemd-udevd-control.socket
|
|
Warning: Stopping systemd-udevd.service, but it can still be activated by:
|
|
systemd-udevd-control.socket
|
|
systemd-udevd-kernel.socket
|
|
|
|
* 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.

* support *static* (/run) hibernate inhibitors. All rpm -i actions should completely prevent any
|
|
sort of hibernate action until the next reboot. If the kernel or any other base tool is replaced
|
|
by rpm, the resume path might fail, the for resume needed kernel might even be uninstalled, and
|
|
the whole situation leads directly to data loss.
|
|
|
|
F18:
|
|
|
|
* journald: warn if we drop messages we forward to the syslog socket
|
|
|
|
* refuse automount triggers when automount is queued for stop, much like we refuse socket triggers when sockets are queued for stop
|
|
|
|
* perfomance messages for selinux are gone from debug log?
|
|
|
|
* There's something wrong with escaping unit names: http://lists.freedesktop.org/archives/systemd-devel/2012-August/006292.html
|
|
|
|
* logind: different policy actions for idle, suspend, shutdown blockers: allow idle blockers by default, don't allow suspend blockers by default
|
|
|
|
* selinux: merge systemd selinux access controls (dwalsh)
|
|
|
|
Features:
|
|
|
|
* move cryptsetup key caching into kernel keyctl?
|
|
|
|
* make nspawn work without terminal
|
|
|
|
* hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
|
|
|
|
* after deserializing sockets in socket.c we should reapply sockopts and things
|
|
|
|
* does vasprintf advance the struct vaargs? http://pastie.org/pastes/4712773/text
|
|
|
|
* do shutdown audit/utmp msgs inside of PID 1, get rid of systemd-update-utmp-runlevel
|
|
|
|
* make timer units go away after they elapsed
|
|
|
|
* http://lists.freedesktop.org/archives/systemd-devel/2012-September/006502.html
|
|
|
|
* don't use writev() in tmpfiles for sake of compat with sysfs?
|
|
|
|
* come up with a nice way to write queue/read_ahead_kb for a block device without interfering with readahead
|
|
|
|
* journald: add kernel cmdline option to disable ratelimiting for debug purposes
|
|
|
|
* Add a way to reference the machine/boot ID from ExecStart= and similar command lines
|
|
|
|
* move PID 1 segfaults to /var/lib/systemd/coredump?
|
|
|
|
* Document word splitting syntax for ExecStart= and friends
|
|
|
|
* when writing journal entries order field items by their address to improve speed on rotating media
|
|
|
|
* create /sbin/init symlinks from the build system
|
|
|
|
* Query Paul Moore about relabelling socket fds while they are open
|
|
|
|
* move keymaps to /usr/lib/... rather than /usr/lib/udev/...
|
|
|
|
* journald: check whether it is OK if the client can still modify delivered journal entries
|
|
|
|
* json: use jensson
|
|
|
|
* json: properly serialize multiple fields with the same name per entry
|
|
|
|
* journal live copy, based on libneon (client) and libmicrohttpd
|
|
|
|
* document in wiki json serialization
|
|
|
|
* system-wide seccomp filter
|
|
|
|
* securityfs: don't mount in container
|
|
|
|
* slave/shared remount root fs in container might clash with CAP_SYS_MOUNTS
|
|
|
|
* ability to pass fds into systemd
|
|
|
|
* system.conf should have controls for cgroups
|
|
|
|
* bind mount read-only the cgroup tree higher than than nspawn
|
|
|
|
* currently system services appear not to generate core dumps...
|
|
|
|
* wall messages for shutdown should move to logind
|
|
|
|
* allow writing multiple conditions in unit files on one line
|
|
|
|
* 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
|
|
|
|
* enforce limits on fds openened by socket units
|
|
|
|
* explore multiple service instances per listening socket idea
|
|
|
|
* 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.
|
|
|
|
* maybe make systemd-detect-virt suid? or use fscaps?
|
|
|
|
* shutdown: don't read-only mount anything when running in container
|
|
|
|
* nspawn: --read-only is not applied recursively to submounts
|
|
|
|
* MountFlags=shared acts as MountFlags=slave right now.
|
|
|
|
* ReadOnlyDirectories= is not applied recursively to submounts
|
|
|
|
* drop PID 1 reloading, only do reexecing (difficult: Reload()
|
|
currently is properly synchronous, Reexec() is weird, because we
|
|
can't delay the response properly until we are back, so instead of
|
|
being properly synchronous we just keep open the fd and close it
|
|
when done. That means clients don't get a succesful method reply,
|
|
but much rather a disconnect on success.
|
|
|
|
* document that service reload may be implemented as service reexec
|
|
|
|
* remember which condition failed for services, not just the fact that something failed
|
|
|
|
* use opterr = 0 for all getopt tools
|
|
|
|
* properly handle loop back mounts via fstab, especially regards to fsck/passno
|

|
|
* allow services with no ExecStart= but with an ExecStop=
|
|
|
|
* add proper journal support to "systemctl --user status ..."
|
|
|
|
* add _SYSTEMD_USER_UNIT= field to journal entries
|
|
|
|
* dracut-shutdown needs to be ordered before unmounting /boot
|
|
|
|
* initialize the hostname from the fs label of /, if /etc/hostname does not exist?
|
|
|
|
* 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.
|
|
|
|
* logind: ignore inactive login screens when checking whether power key should be handled
|
|
|
|
* rename "userspace" to "core-os"
|
|
|
|
* systemctl: "Journal has been rotated since unit was started." message is misleading
|
|
|
|
* syscall filter: add knowledge about compat syscalls
|
|
|
|
* syscall filter: don't enforce no new privs?
|
|
|
|
* syscall filter: option to return EPERM rather than SIGSYS?
|
|
|
|
* syscall filter: port to libseccomp
|
|
|
|
* logind: wakelock/opportunistic suspend support
|
|
|
|
* 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
|
|
|
|
* .device aliases need to be implemented with the "following" logic, probably.
|
|
|
|
* refuse taking lower-case variable names in sd_journal_send() and friends.
|
|
|
|
* 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: we currently rotate only after MaxUse+MaxFilesize has been reached.
|
|
|
|
* Document:
|
|
- PID 1 D-Bus API
|
|
|
|
* 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 /etc/fstab and /boot is empty
|

|
|
|

|
|

|
|
|
* 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)
|
|
|
|
* 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:

|
|
IdleActionDelay=...
|
|
SessionIdleMode=(explicit|ignore|login)
|
|
ForceShutdown=(yes|no)
|
|

|
|
|

|
|
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

|
|
|

|
|
|
|
* 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)

|
|
|
|
* add command to systemctl to plot dependency graph as tree (see rhbz 795365)
|
|
|
|
* add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
|
|
|
|

|
|
|
|
* 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)

|
|
|
|
* hide PAM/TCPWrap options in fragment parser when compile time disabled
|

|
|
* when we automatically restart a service, ensure we restart its rdeps, too.

|
* 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
|
|
|
|
* Make it possible to set the keymap independently from the font on
|
|
the kernel cmdline. Right now setting one resets also the other.

|
* 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(errno);
|
|
|
|
* pahole
|
|
|
|
* set_put(), hashmap_put() return values check. i.e. == 0 doesn't free()!
|
|
|
|
* use secure_getenv() instead of getenv() where appropriate
