CHANGES WITH 182:
|
|
* udev: all udev sources are merged into the systemd source tree now.
|
|
All future udev development will happen in the systemd tree. It
|
|
is still fully supported to use the udev daemon and tools without
|
|
systemd running, like in initramfs or other init systems. Building
|
|
udev though, will require the *build* of the systemd tree, but
|
|
udev can be properly *run* without systems.
|
|
|
|
* udev: /lib/udev/devices/ are not read anymore; systemd-tmpfiles
|
|
should be used to create dead device nodes as workarounds for broken
|
|
subsystems.
|
|
|
|
* udev: RUN+="socket:..." and udev_monitor_new_from_socket() is
|
|
no longer supported. udev_monitor_new_from_netlink() needs to be
|
|
used to subscribe to events.
|
|
|
|
* udev: when udevd is started by systemd, processes which are left
|
|
behind by forking them off of udev rules, are unconditionally cleaned
|
|
up and killed now after the event handling has finished. Services or
|
|
daemons must be started as systemd services. Services can be
|
|
pulled-in by udev to ge started, but they can no longer be directly
|
|
forked by udev rules.
|
|
|
|
* udev: the daemon binary is called systemd-udevd now and installed
|
|
in /usr/lib/systemd/. Standalone builds or non-systemd systems need
|
|
to adapt to that, create symlink, or rename the binary after building
|
|
it.
|
|
|
|
* Libudev does no longer provide these symbols:
|
|
udev_monitor_from_socket()
|
|
udev_queue_get_failed_list_entry()
|
|
udev_get_{dev,sys,run}_path()
|
|
The verions number was bumped and symbol versioning introduced.
|
|
|
|
* systemd-logingctl and systemd-journalctl have been renamed
|
|
to logingctl and journalctl to match systemctl.
|
|
|
|
* The config files: /etc/systemd/systemd-logind.conf and
|
|
/etc/systemd/systemd-journald.conf have been renamed to
|
|
logind.conf and journald.conf. Package updates should rename
|
|
the files to the new names on upgrade.
|
|
|
|
CHANGES WITH 44:
|
|
* This is mostly a bugfix release
|
|
|
|
* Support optional initialization of the machine ID from the
|
|
KVM or container configured UUID.
|
|
|
|
* Support immediate reboots with "systemctl reboot -ff"
|
|
|
|
* Show /etc/os-release data in systemd-analyze output
|
|
|
|
* Many bugfixes for the journal, including endianess fixes and
|
|
ensuring that disk space enforcement works
|
|
|
|
* sd-login.h is C++ comptaible again
|
|
|
|
* Extend the /etc/os-release format on request of the Debian
|
|
folks
|
|
|
|
* We now refuse non-UTF8 strings used in various configuration
|
|
and unit files. This is done to ensure we don't pass invalid
|
|
data over D-Bus or expose it elsewhere.
|
|
|
|
* Register Mimo USB Screens as suitable for automatic seat
|
|
configuration
|
|
|
|
* Read SELinux client context from journal clients in a race
|
|
free fashion
|
|
|
|
* Reorder configuration file lookup order. /etc now always
|
|
overrides /run in order to allow the administrator to always
|
|
and unconditionally override vendor supplied or
|
|
automatically generated data.
|
|
|
|
* The various user visible bits of the journal now have man
|
|
pages. We still lack man pages for the journal API calls
|
|
however.
|
|
|
|
* We now ship all man pages in HTML format again in the
|
|
tarball.

CHANGES WITH 43:
|
|
* This is mostly a bugfix release
|
|
|
|
* systems lacking /etc/os-release are no longer supported.
|
|
|
|
* Various functionality updates to libsystemd-login.so
|
|
|
|
* Track class of PAM logins to distuingish greeters from
|
|
normal user logins.

CHANGES WITH 42:
|
|
* This is an important bugfix release for v41.
|
|
|
|
* Building man pages is now optional which should be useful
|
|
for those building systemd from git but unwilling to install
|
|
xsltproc.
|
|
|
|
* Watchdog support for supervising services is now usable. In
|
|
a future release support for hardware watchdogs
|
|
(i.e. /dev/watchdog) will be added building on this.
|
|
|
|
* Service start rate limiting is now configurable and can be
|
|
turned off per service. When a start rate limit is hit a
|
|
reboot can automatically be triggered.
|
|
|
|
* New CanReboot(), CanPowerOff() bus calls in systemd-logind.

|
CHANGES WITH 41:
|
|
* The systemd binary is installed /usr/lib/systemd/systemd now;
|
|
An existing /sbin/init symlink needs to be adapted with the
|
|
package update.
|
|
|
|
* The code that loads kernel modules has been ported to invoke
|
|
libkmod directly, instead of modprobe. This means we do not
|
|
support systems with module-init-tools anymore.
|
|
|
|
* Watchdog support is now already useful, but still not
|
|
complete.
|
|
|
|
* A new kernel command line option systemd.setenv= is
|
|
understood to set system wide environment variables
|
|
dynamically at boot.
|
|
|
|
* We now limit the set of capabilities of systemd-journald.
|
|
|
|
* We now set SIGPIPE to ignore by default, since it only is
|
|
useful in shell pipelines, and has little use in general
|
|
code. This can be disabled with IgnoreSIPIPE=no in unit
|
|
files.

CHANGES WITH 40:
|
|
* This is mostly a bugfix release
|
|
|
|
* We now expose the reason why a service failed in the
|
|
"Result" D-Bus property.
|
|
|
|
* Rudimentary service watchdog support (will be completed over
|
|
the next few releases.)
|
|
|
|
* When systemd forks off in order execute some service we will
|
|
now immediately changes its argv[0] to reflect which process
|
|
it will execute. This is useful to minimize the time window
|
|
with a generic argv[0], which makes bootcharts more useful
|

CHANGES WITH 39:
|
|
* This is mostly a test release, but incorporates many
|
|
bugfixes.
|
|
|
|
* New systemd-cgtop tool to show control groups by their
|
|
resource usage.
|
|
|
|
* Linking against libacl for ACLs is optional again. If
|
|
disabled, support tracking device access for active logins
|
|
goes becomes unavailable, and so does access to the user
|
|
journals by the respective users.
|
|
|
|
* If a group "adm" exists, journal files are automatically
|
|
owned by them, thus allow members of this group full access
|
|
to the system journal as well as all user journals.
|
|
|
|
* The journal now stores the SELinux context of the logging
|
|
client for all entries.
|
|
|
|
* Add C++ inclusion guards to all public headers
|
|
|
|
* New output mode "cat" in the journal to print only text
|
|
messages, without any meta data like date or time.
|
|
|
|
* Include tiny X server wrapper as a temporary stop-gap to
|
|
teach XOrg udev display enumeration. This is used by display
|
|
managers such as gdm, and will go away as soon as XOrg
|
|
learned native udev hotplugging for display devices.
|
|
|
|
* Add new systemd-cat tool for executing arbitrary programs
|
|
with STDERR/STDOUT connected to the journal. Can also act as
|
|
BSD logger replacement, and does so by default.
|
|
|
|
* Optionally store all locally generated coredumps in the
|
|
journal along with meta data.
|
|
|
|
* systemd-tmpfiles learnt four new commands: n, L, c, b, for
|
|
writing short strings to files (for usage for /sys), and for
|
|
creating symlinks, character and block device nodes.
|
|
|
|
* New unit file option ControlGroupPersistent= to make cgroups
|
|
persistent, following the mechanisms outlined in
|
|
http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups
|
|
|
|
* Support multiple local RTCs in a sane way
|
|
|
|
* No longer monopolize IO when replaying readahead data on
|
|
rotating disks, since we might starve non-file-system IO to
|
|
death, since fanotify() will not see accesses done by blkid,
|
|
or fsck.
|
|
|
|
* Don't show kernel threads in systemd-cgls anymore, unless
|
|
requested with new -k switch.

CHANGES WITH 38:
|
|
* This is mostly a test release, but incorporates many
|
|
bugfixes.
|
|
|
|
* The git repository moved to:
|
|
git://anongit.freedesktop.org/systemd/systemd
|
|
ssh://git.freedesktop.org/git/systemd/systemd
|
|
|
|
* First release with the journal
|
|
http://0pointer.de/blog/projects/the-journal.html
|
|
|
|
* The journal replaces both systemd-kmsg-syslogd and
|
|
systemd-stdout-bridge.
|
|
|
|
* New sd_pid_get_unit() API call in libsystemd-logind
|
|
|
|
* Many systemadm clean-ups
|
|
|
|
* Introduce remote-fs-pre.target which is ordered before all
|
|
remote mounts and may be used to start services before all
|
|
remote mounts.
|
|
|
|
* Added Mageia support
|
|
|
|
* Add bash completion for systemd-loginctl
|
|
|
|
* Actively monitor PID file creation for daemons which exit in
|
|
the parent process before having finished writing the PID
|
|
file in the daemon process. Daemons which do this need to be
|
|
fixed (i.e. PID file creation must have finished before the
|
|
parent exits), but we now react a bit more gracefully to them.
|
|
|
|
* Add colourful boot output, mimicking the well-known output
|
|
of existing distributions.
|
|
|
|
* New option PassCredentials= for socket units, for
|
|
compatibility with a recent kernel ABI breakage.
|
|
|
|
* /etc/rc.local is now hooked in via a generator binary, and
|
|
thus will no longer act as synchronization point during
|
|
boot.
|
|
|
|
* systemctl list-unit-files now supports --root=.
|
|
|
|
* systemd-tmpfiles now understands two new commands: z, Z for
|
|
relabelling files according to the SELinux database. This is
|
|
useful to apply SELinux labels to specific files in /sys,
|
|
among other things.
|
|
|
|
* Output of SysV services is now forwarded to both the console
|
|
and the journal by default, not only just the console.
|
|
|
|
* New man pages for all APIs from libsystemd-login.
|
|
|
|
* The build tree got reorganized and a the build system is a
|
|
lot more modular allowing embedded setups to specifically
|
|
select the components of systemd they are interested in.
|
|
|
|
* Support for Linux systems lacking the kernel VT subsystem is
|
|
restored.
|
|
|
|
* configure's --with-rootdir= got renamed to
|
|
--with-rootprefix= to follow the naming used by udev and
|
|
kmod
|
|
|
|
* Unless specified otherwise we'll now install to /usr instead
|
|
of /usr/local by default.
|
|
|
|
* Processes with '@' in argv[0][0] are now excluded from the
|
|
final shut-down killing spree, following the logic explained
|
|
in:
|
|
http://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons
|
|
|
|
* All processes remaining in a service cgroup when we enter
|
|
the START or START_PRE states are now killed with
|
|
SIGKILL. That means it is no longer possible to spawn
|
|
background processes from ExecStart= lines (which was never
|
|
supported anyway, and bad style).
|
|
|
|
* New PropagateReloadTo=/PropagateReloadFrom= options to bind
|
|
reloading of units together.
