Heya, Many new features, even more bugfixes!
http://www.freedesktop.org/software/systemd/systemd-217.tar.xz CHANGES WITH 217: * journalctl gained the new options -t/--identifier= to match on the syslog identifier (aka "tag"), as well as --utc to show log timestamps in the UTC timezone. journalctl now also accepts -n/--lines=all to disable line capping in a pager. * Services can notify the manager before they start a reload (by sending RELOADING=1) or shutdown (by sending STOPPING=1). This allows the manager to track and show the internal state of daemons and closes a race condition when the process is still running but has closed its D-Bus connection. * Services with Type=oneshot do not have to have any ExecStart commands anymore. * User units are now loaded also from $XDG_RUNTIME_DIR/systemd/user/. This is similar to the /run/systemd/user directory that was already previously supported, but is under the control of the user. * Job timeouts (i.e. time-outs on the time a job that is queued stays in the run queue) can now optionally result in immediate reboot or power-off actions (JobTimeoutAction= and JobTimeoutRebootArgument=). This is useful on ".target" units, to limit the maximum time a target remains undispatched in the run queue, and to trigger an emergency operation in such a case. This is now used by default to turn off the system if boot-up (as defined by everything in basic.target) hangs and does not complete for at least 15min. Also, if power-off or reboot hang for at least 30min an immediate power-off/reboot operation is triggered. This functionality is particularly useful to increase reliability on embedded devices, but also on laptops which might accidentally get powered on when carried in a backpack and whose boot stays stuck in a hard disk encryption passphrase question. * systemd-logind can be configured to also handle lid switch events even when the machine is docked or multiple displays are attached (HandleLidSwitchDocked= option). * A helper binary and a service have been added which can be used to resume from hibernation in the initramfs. A generator will parse the resume= option on the kernel command-line to trigger resume. * A user console daemon systemd-consoled has been added. Currently, it is a preview, and will so far open a single terminal on each session of the user marked as Desktop=systemd-console. * Route metrics can be specified for DHCP routes added by systemd-networkd. * The SELinux context of socket-activated services can be set from the information provided by the networking stack (SELinuxContextFromNet= option). * Userspace firmware loading support has been removed and the minimum supported kernel version is thus bumped to 3.7. * Timeout for udev workers has been increased from 1 to 3 minutes, but a warning will be printed after 1 minute to help diagnose kernel modules that take a long time to load. * Udev rules can now remove tags on devices with TAG-="foobar". * systemd's readahead implementation has been removed. In many circumstances it didn't give expected benefits even for rotational disk drives and was becoming less relevant in the age of SSDs. As none of the developers has been using rotating media anymore, and nobody stepped up to actively maintain this component of systemd it has now been removed. * Swap units can use Discard= to specify discard options. Discard options specified for swaps in /etc/fstab are now respected. * Docker containers are now detected as a separate type of virtualization. * The Password Agent protocol gained support for queries where the user input is shown, useful e.g. for user names. systemd-ask-password gained a new --echo option to turn that on. * The default sysctl.d/ snippets will now set: net.core.default_qdisc = fq_codel This selects Fair Queuing Controlled Delay as the default queuing discipline for network interfaces. fq_codel helps fight the network bufferbloat problem. It is believed to be a good default with no tuning required for most workloads. Downstream distributions may override this choice. On 10Gbit servers that do not do forwarding, "fq" may perform better. Systems without a good clocksource should use "pfifo_fast". * If kdbus is enabled during build a new option BusPolicy= is available for service units, that allows locking all service processes into a stricter bus policy, in order to limit access to various bus services, or even hide most of them from the service's view entirely. * networkctl will now show the .network and .link file networkd has applied to a specific interface. * sd-login gained a new API call sd_session_get_desktop() to query which desktop environment has been selected for a session. * UNIX utmp support is now compile-time optional to support legacy-free systems. * systemctl gained two new commands "add-wants" and "add-requires" for pulling in units from specific targets easily. * If the word "rescue" is specified on the kernel command line the system will now boot into rescue mode (aka rescue.target), which was previously available only by specifying "1" or "systemd.unit=rescue.target" on the kernel command line. This new kernel command line option nicely mirrors the already existing "emergency" kernel command line option. * New kernel command line options mount.usr=, mount.usrflags=, mount.usrfstype= have been added that match root=, rootflags=, rootfstype= but allow mounting a specific file system to /usr. * The $NOTIFY_SOCKET is now also passed to control processes of services, not only the main process. * This version reenables support for fsck's -l switch. This means at least version v2.25 of util-linux is required for operation, otherwise dead-locks on device nodes may occur. Again: you need to update util-linux to at least v2.25 when updating systemd to v217. * The "multi-seat-x" tool has been removed from systemd, as its functionality has been integrated into X servers 1.16, and the tool is hence redundant. It is recommended to update display managers invoking this tool to simply invoke X directly from now on, again. * Support for the new ALLOW_INTERACTIVE_AUTHORIZATION D-Bus message flag has been added for all of systemd's PolicyKit authenticated method calls has been added. In particular this now allows optional interactive authorization via PolicyKit for many of PID1's privileged operations such as unit file enabling and disabling. * "udevadm hwdb --update" learnt a new switch "--usr" for placing the rebuilt hardware database in /usr instead of /etc. When used only hardware database entries stored in /usr will be used, and any user database entries in /etc are ignored. This functionality is useful for vendors to ship a pre-built database on systems where local configuration is unnecessary or unlikely. * Calendar time specifications in .timer units now also understand the strings "semi-annually", "quarterly" and "minutely" as shortcuts (in addition to the preexisting "anually", "hourly", ...). * systemd-tmpfiles will now correctly create files in /dev at boot which are marked for creation only at boot. It is recommended to always create static device nodes with 'c!' and 'b!', so that they are created only at boot and not overwritten at runtime. * When the watchdog logic is used for a service (WatchdogSec=) and the watchdog timeout is hit the service will now be terminated with SIGABRT (instead of just SIGTERM), in order to make sure a proper coredump and backtrace is generated. This ensures that hanging services will result in similar coredump/backtrace behaviour as services that hit a segmentation fault.
