[systemd-devel] [ANNOUNCE] systemd 213

Heya! http://www.freedesktop.org/software/systemd/systemd-213.tar.xz Some new features, lots of bugfixes. CHANGES WITH 213: * A new "systemd-timesyncd" daemon has been added for synchronizing the system clock across the network. It implements an SNTP client. In contrast to NTP implementations such as chrony or the NTP reference server this only implements a client side, and does not bother with the full NTP complexity, focusing only on querying time from one remote server and synchronizing the local clock to it. Unless you intend to serve NTP to networked clients or want to connect to local hardware clocks this simple NTP client should be more than appropriate for most installations. The daemon runs with minimal privileges, and has been hooked up with networkd to only operate when network connectivity is available. The daemon saves the current clock to disk every time a new NTP sync has been acquired, and uses this to possibly correct the system clock early at bootup, in order to accommodate for systems that lack an RTC such as the Raspberry Pi and embedded devices, and make sure that time monotonically progresses on these systems, even if it is not always correct. To make use of this daemon a new system user and group "systemd-timesync" needs to be created on installation of systemd. * The queue "seqnum" interface of libudev has been disabled, as it was generally incompatible with device namespacing as sequence numbers of devices go "missing" if the devices are part of a different namespace. * "systemctl list-timers" and "systemctl list-sockets" gained a --recursive switch for showing units of these types also for all local containers, similar in style to the already supported --recursive switch for "systemctl list-units". * A new RebootArgument= setting has been added for service units, which may be used to specify a kernel reboot argument to use when triggering reboots with StartLimitAction=. * A new FailureAction= setting has been added for service units which may be used to specify an operation to trigger when a service fails. This works similarly to StartLimitAction=, but unlike it controls what is done immediately rather than only after several attempts to restart the service in question. * hostnamed got updated to also expose the kernel name, release, and version on the bus. This is useful for executing commands like hostnamectl with the -H switch. systemd-analyze makes use of this to properly display details when running non-locally. * The bootchart tool can now show cgroup information in the graphs it generates. * The CFS CPU quota cgroup attribute is now exposed for services. The new CPUQuota= switch has been added for this which takes a percentage value. Setting this will have the result that a service may never get more CPU time than the specified percentage, even if the machine is otherwise idle. * systemd-networkd learned IPIP and SIT tunnel support. * LSB init scripts exposing a dependency on $network will now get a dependency on network-online.target rather than simply network.target. This should bring LSB handling closer to what it was on SysV systems. * A new fsck.repair= kernel option has been added to control how fsck shall deal with unclean file systems at boot. * The (.ini) configuration file parser will now silently ignore sections whose name begins with "X-". This may be used to maintain application-specific extension sections in unit files. * machined gained a new API to query the IP addresses of registered containers. "machinectl status" has been updated to show these addresses in its output. * A new call sd_uid_get_display() has been added to the sd-login APIs for querying the "primary" session of a user. The "primary" session of the user is elected from the user's sessions and generally a graphical session is preferred over a text one. * A minimal systemd-resolved daemon has been added. It currently simply acts as a companion to systemd-networkd and manages resolv.conf based on per-interface DNS configuration, possibly supplied via DHCP. In the long run we hope to extend this into a local DNSSEC enabled DNS and mDNS cache. * The systemd-networkd-wait-online tool is now enabled by default. It will delay network-online.target until a network connection has been configured. The tool primarily integrates with networkd, but will also make a best effort to make sense of network configuration performed in some other way. * Two new service options StartupCPUShares= and StartupBlockIOWeight= have been added that work similarly to CPUShares= and BlockIOWeight= however only apply during system startup. This is useful to prioritize certain services differently during bootup than during normal runtime. * hostnamed has been changed to prefer the statically configured hostname in /etc/hostname (unless set to 'localhost' or empty) over any dynamic one supplied by dhcp. With this change the rules for picking the hostname match more closely the rules of other configuration settings where the local administrator's configuration in /etc always overrides any other settings.
