Hi all,
systemd v202 should be landed in Factory soon. It contains a lot of
changes (and bug fixes) compared to v195 we had in 12.3, like (this is
an extract from the .changes I wrote):
+ udev now supports different naming policies for network
interface for predictable names (this one is disabled
by /usr/lib/tmpfiles.d/network.conf until network team had a chance to
look at it and test it). This should be enabled by default in Factory
soon (see
http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterface... )
This can be also be turned off with kernel command line switch:
net.ifnames=0 (when the tmpfiles.d is removed in the near future)
+ udev gained support for loading additional device properties
from an indexed database. %udev_hwdb_update macro should be
used by packages adding entries to this database.
+ Journal gained support for "Message Catalog", indexed database
to link up additional information with journal entries.
%journal_catalog_update macro should be used by packages adding
%entries to this database.
+ New rpm macros has been added: %udev_rules_update(),
%_udevhwdbdir, %_udevrulesdir, %_journalcatalogdir,
%_tmpfilesdir, %_sysctldir.
+ "age" field for tmpfiles entries can be set to 0, forcing
removal of files matching this entry.
+ coredumpctl gained "gdb" verb to invoke gdb on selected
coredump.
+ In service files, %U can be used for configured user name of
the service.
+ nspawn can be invoked without a controlling TTY.
+ systemd and nspawn can accept socket file descriptors when
started for socket activation. This allow socket activated
nspawn containers.
+ logind can now automatically suspend/hibernate/shutdown system
on idle.
+ ConditionACPower can be used in unit file to detect if AC power
source is connected or if system is on battery power.
+ EnvironmentFile= in unit files supports file globbing.
+ Behaviour of PrivateTmp=, ReadWriteDirectories=,
ReadOnlyDirectories= and InaccessibleDirectories= has
changed. The private /tmp and /var/tmp directories are now
shared by all processes of a service (which means
ExecStartPre= may now leave data in /tmp that ExecStart= of
the same service can still access). When a service is
stopped its temporary directories are immediately deleted
(normal clean-up with tmpfiles is still done in addition to
this though).
+ Resource limits (as exposed by cgroup controlers) can be
controlled dynamically at runtime for all units, using
"systemctl set-cgroup-attr foobar.server cgroup.attribute
value". Those settings are stored persistenly on disk.
+ systemd-vconsole-setup will now copy all fonts settings to all
allocated VTs.
+ timedated now exposes CanNTP property to indicate if a local
NTP service is available.
+ pstore file system is mounted by default, if available.
+ SMACK policies are loaded at early boot, if available.
+ Timer units now support calendar time events.
+ systemd-detect-virt detect xen PVs.
+ Some distributions specific LSB targets has been dropped:
$x-display-manager, $mail-transfer-agent,
$mail-transport-agent, $mail-transfer-agent, $smtp, $null. As
well mail-transfer-agent.target and syslog.target has been
removed.
+ systemd-journal-gatewayd gained SSL support and now runs as
unprivileged user/group
"systemd-journal-gateway:systemd-journal-gateway"
+ systemd-analyze will read, when available, boot time
performance from EFI variable from boot loader supporting it.
+ A new generator for automatically mounting EFI System Partition
(ESP) to /boot (if empty and no other file system has been
configured in fstab for it).
+ logind will now send out PrepareForSleep(false) out
unconditionally, after coming back from suspend.
+ tmpfiles gained a new "X" line type, that allows
configuration of files and directories (with wildcards) that
shall be excluded from automatic cleanup ("aging").
+ udev default rules set the device node permissions now only
at "add" events, and do not change them any longer with a
later "change" event.
+ A new bootctl tool has been added that is an interface for
certain EFI boot loader operations.
+ A new tool kernel-install has been added to install kernel
images according to Boot Loader Specification.
+ A new tool systemd-activate can be used to test socket
activation.
+ A new group "systemd-journal" is now owning journal files,
replacing "adm" group.
+ journalctl gained "--reverse" to show output in reverse order,
"--pager-end" to jump at the end of the journal in the
pager (only less is supported) and "--user-unit" to filter for
user units.
+ New unit files has been addedto ease for systemd usage in
initrd.
+ "systemctl start" now supports "--irreversible" to queue
operations which can be reserved. It is now used to make
shutdown requests more robust.
+ Auke Kok's bootchart has been merged and relicensed to
LGPLv2.1+.
+ nss-myhostname has been merged in systemd codebase.
+ some defaults sysctl values are now set by default: the safe
sysrq options are turned on, IP route verification is turned
on, and source routing disabled. The recently added hardlink
and softlink protection of the kernel is turned on.
+ journald will now explicitly flush journal files to disk at the
latest 5 min after each write and will mark file offline until
next read. This should increase reliability in case of crash.
+ remote-fs-setup.target target has been added to pull in
specific services when at least one remote file system is to be
mounted.
+ timers.target and paths.target have been added as canonical
targets to pull user timer and path units, similar to
sockets.targets.
+ udev daemon now sets default number of worker processes in
parallel based on number of CPUs instead of RAM.
+ Most unit file settings which takes likst of items can now be
reset by assigning empty string to them, using drop-in.
+ Add support for drop-in configuration file for units.
+ Most unit file settings which takes likst of items can now be
reset by assigning empty string to them, using drop-in.
+ 'hostnamectl set-hostname' allows setting FQDN hostnames.
+ fractional time intervals are now parsed properly.
+ localectl can list available X11 keymaps.
+ systemd-analyze dot can filter for specific units and has been
rewritten in C.
+ systemctl gained "list-dependencies" command.
+ Inhibitors are now honored no only in GNOME.
+ 'systemctl list-jobs' got some polishing. '--type=' argument
may now be passed more than once. 'systemctl list-sockets' has
been added.
+ systemd gained a new unit 'systemd-static-nodes.service'
that generates static device nodes earlier during boot, and
can run in conjunction with udev.
+ systemd-nspawn now places all containers in the new /machine
top-level cgroup directory in the name=systemd hierarchy.
+ bootchart can now store its data in the journal.
+ journactl can now take multiple --unit= and --user-unit=
switches.
+ The cryptsetup logic now understands the "luks.key=" kernel
command line switch. If a configured key file is missing, it
will fallback to prompting the user.
