[systemd-devel] [ANNOUNCE] systemd 206

Heya! After introducing all those new concepts in 205 this release fixes a few issues in that new code, and adds pretty much all missing documentation for it. Also, lots of bits and pieces that waited to be merged got merged, so we have some new features as well. http://www.freedesktop.org/software/systemd/systemd-206.tar.xz CHANGES WITH 206: * The documentation has been updated to cover the various new concepts introduced with 205. * Unit files now understand the new %v specifier which resolves to the kernel version string as returned by "uname -r". * systemctl now supports filtering the unit list output by load state, active state and sub state, using the new --state= parameter. * "systemctl status" will now show the results of the condition checks (like ConditionPathExists= and similar) of the last start attempts of the unit. They are also logged to the journal. * "journalctl -b" may now be used to look for boot output of a specific boot. Try "journalctl -b -1" for the previous boot, but the syntax is substantially more powerful. * "journalctl --show-cursor" has been added which prints the cursor string the last shown log line. This may then be used with the new "journalctl --after-cursor=" switch to continue browsing logs from that point on. * "journalctl --force" may now be used to force regeneration of an FSS key. * Creation of "dead" device nodes has been moved from udev into kmod and tmpfiles. Previously, udev would read the kmod databases to pre-generate dead device nodes based on meta information contained in kernel modules, so that these would be auto-loaded on access rather then at boot. As this doesn't really have much to do with the exposing actual kernel devices to userspace this has always been slightly alien in the udev codebase. Following the new scheme kmod will now generate a runtime snippet for tmpfiles from the module meta information and it now is tmpfiles' job to the create the nodes. This also allows overriding access and other parameters for the nodes using the usual tmpfiles facilities. As side effect this allows us to remove the CAP_SYS_MKNOD capability bit from udevd entirely. * logind's device ACLs may now be applied to these "dead" devices nodes too, thus finally allowing managed access to devices such as /dev/snd/sequencer whithout loading the backing module right-away. * A new RPM macro has been added that may be used to apply tmpfiles configuration during package installation. * systemd-detect-virt and ConditionVirtualization= now can detect User-Mode-Linux machines (UML). * journald will now implicitly log the effective capabilities set of processes in the message metadata. * systemd-cryptsetup has gained support for TrueCrypt volumes. * The initrd interface has been simplified (more specifically, support for passing performance data via environment variables and fsck results via files in /run has been removed). These features were non-essential, and are nowadays available in a much nicer way by having systemd in the initrd serialize its state and have the hosts systemd deserialize it again. * The udev "keymap" data files and tools to apply keyboard specific mappings of scan to key codes, and force-release scan code lists have been entirely replaced by a udev "keyboard" builtin and a hwdb data file. * systemd will now honour the kernel's "quiet" command line argument also during late shutdown, resulting in a completely silent shutdown when used. * There's now an option to control the SO_REUSEPORT socket option in .socket units. * Instance units will now automatically get a per-template subslice of system.slice unless something else is explicitly configured. For example, instances of sshd at .service will now implicitly be placed in system-sshd.slice rather than system.slice as before. * Test coverage support may now be enabled at build time.
