2016-06-13core: parse `rd.rescue` and `rd.emergency` as initrd-specific shorthands (#3488)Ivan Shapovalov
Typing `rd.rescue` is easier than `rd.systemd.unit=rescue.target`.
2016-04-26core: set start job timeout from the kernel commandline (#3112)tblume
Add the boot parameter: systemd.default_timeout_start_sec to allow modification of the default start job timeout at boot time.
2016-01-12core: Add machine-id settingNils Carlson
Allow for overriding all other machine-ids which may be present on the system using a kernel command line systemd.machine_id or --machine-id= option. This is especially useful for network booted systems where the machine-id needs to be static, or for containers where a specific machine-id is wanted.

2015-09-29core: rework crash handlingLennart Poettering
This introduces a new systemd.crash_reboot=1 kernel command line option that triggers a reboot after crashing. This also cleans up crash VT handling. Specifically, it cleans up the configuration setting, to be between 1..63 or a boolean. This is to replace the previous logic where "-1" meant disabled. We continue to accept that setting, but only document the boolean syntax instead. This also brings the documentation of the default settings in sync with what actually happens. The CrashChVT= configuration file setting is renamed to CrashChangeVT=, following our usual logic of not abbreviating unnecessarily. The old setting stays support for compat reasons. Fixes #1300
2015-06-18man: revert dynamic paths for split-usr setupsTom Gundersen
This did not really work out as we had hoped. Trying to do this upstream introduced several problems that probably makes it better suited as a downstream patch after all. At any rate, it is not releaseable in the current state, so we at least need to revert this before the release. * by adjusting the path to binaries, but not do the same thing to the search path we end up with inconsistent man-pages. Adjusting the search path too would be quite messy, and it is not at all obvious that this is worth the effort, but at any rate it would have to be done before we could ship this. * this means that distributed man-pages does not make sense as they depend on config options, and for better or worse we are still distributing man pages, so that is something that definitely needs sorting out before we could ship with this patch. * we have long held that split-usr is only minimally supported in order to boot, and something we hope will eventually go away. So before we start adding even more magic/effort in order to make this work nicely, we should probably question if it makes sense at all.
2015-05-28man: generate configured paths in manpagesFilipe Brandenburger
In particular, use /lib/systemd instead of /usr/lib/systemd in distributions like Debian which still have not adopted a /usr merge setup. Use XML entities from man/custom-entities.ent to replace configured paths while doing XSLT processing of the original XML files. There was precedent of some files (such as systemd.generator.xml) which were already using this approach. This addresses most of the (manual) fixes from this patch: http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/patches/Fix-paths-in-man-pages.patch?h=experimental-220 The idea of using generic XML entities was presented here: http://lists.freedesktop.org/archives/systemd-devel/2015-May/032240.html This patch solves almost all the issues, with the exception of: - Path to /bin/mount and /bin/umount. - Generic statements about preference of /lib over /etc. These will be handled separately by follow up patches. Tested: - With default configure settings, ran "make install" to two separate directories and compared the output to confirm they matched exactly. - Used a set of configure flags including $CONFFLAGS from Debian: http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/rules Installed the tree and confirmed the paths use /lib/systemd instead of /usr/lib/systemd and that no other unexpected differences exist. - Confirmed that `make distcheck` still passes.

2014-08-26hibernate-resume-generator: add a generator for instantiating the resume unit.Ivan Shapovalov
hibernate-resume-generator understands resume= kernel command line parameter and instantiates the systemd-resume@.service accordingly if it is passed. This enables resume from hibernation using device specified on the kernel command line, and it may be specified either as "/dev/disk/by-foo/bar" or "FOO=bar", not only "/dev/sdXY" which is understood by the in-kernel implementation. So now resume= is brought on par with root= in terms of possible ways to specify a device.
2014-07-07man: add a mapping for external manpagesZbigniew Jędrzejewski-Szmek
It is annoying when we have dead links on fd.o. Add project='man-pages|die-net|archlinux' to <citerefentry>-ies. In generated html, add external links to http://man7.org/linux/man-pages/man, http://linux.die.net/man/, https://www.archlinux.org/. By default, pages in sections 2 and 4 go to man7, since Michael Kerrisk is the autorative source on kernel related stuff. The rest of links goes to linux.die.net, because they have the manpages. Except for the pacman stuff, since it seems to be only available from archlinux.org. Poor gummiboot gets no link, because gummitboot(8) ain't to be found on the net. According to common wisdom, that would mean that it does not exist. But I have seen Kay using it, so I know it does, and deserves to be found. Can somebody be nice and put it up somewhere?

2014-05-16fsck: Allow to specify the fsck repair option in the cmdlineHolger Hans Peter Freyther
Some unattended systems do not have a console attached and entering the default rescue mode will not be too helpful. Allow to specify the "-y" option to attempt to fix all filesystem errors. Manually verified by downloading an image.gz of e2fsprogs, using losetup and running systemd-fsck on the loop device and varying the fsck.repair=preen|yes|no option.
2014-03-14journald: add support for wall forwardingSebastian Thorarensen
This will let journald forward logs as messages sent to all logged in users (like wall). Two options are added: * ForwardToWall (default yes) * MaxLevelWall (default emerg) 'ForwardToWall' is overridable by kernel command line option 'systemd.journald.forward_to_wall'. This is used to emulate the traditional syslogd behaviour of sending emergency messages to all logged in users.

2013-10-19kerne-command-line: introduce option 'systemd.restore_state'Tom Gundersen
When set to 0 this will stop tools like the backlight and rfkill tools to restore state from previous boot. This is useful in case the stored state is bogus to the extent that it is preventing you from resetting it (e.g., the backlight settings cause the screen to be off on boot on a system where the backlight can not be adjusted directly from the keyboard).

2013-01-26man: extend systemd.directives(7) to all manual pagesZbigniew Jędrzejewski-Szmek
New sections are added: PAM options, crypttab options, commandline options, miscellaneous. The last category will be used for all untagged <varname> elements. Commandline options sections is meant to be a developer tool: when adding an option it is sometimes useful to be able to check if similarly named options exist elsewhere.

2012-06-25units: rename fsck@.service to systemd-fsck@.serviceLennart Poettering
The rule is that units that encapsulate our own code are prefixed with "systemd-". Since the fsck units invoke our own code, hence add the missing prefix. Since a long long time the fsck units didn't invoke the naked fsck binaries anymore, and it is unlikely that this well ever change. On the opposite: the code in systemd-fsck will probably get more complex over time to handle fsck progress to plymouth forwarding. Same for quotacheck (but not quotaon!)

2012-06-22core: remove sysv_console optionLennart Poettering
This option never made much sense. It was originally intended to make sure that the usual startup output of sysv scripts goes to the terminal. However, since SysV scripts started from a terminal would not output to that terminal, but rather /dev/console this effect was more often than not actually taking place. Nowadays systemd has much nicer boot time status output than SysV which makes the sysv output redundant. Finally, all output of services goes to the journal anyway, and is not lost. Hence, let's drop this option, and simplify things a bit.
