man: document that logind's RemoveIPC= option excepts all system users Fixes #2324.

logind: update documentation for cf7d1a30e44

logind: change default to UserTasksMax= to 4096

logind: add a new UserTasksMax= setting to logind.conf This new setting configures the TasksMax= field for the slice objects we create for each user. This alters logind to create the slice unit as transient unit explicitly instead of relying on implicit generation of slice units by simply starting them. This also enables us to set a friendly description for slice units that way.

doc: correct orthography, word forms and missing/extraneous words

man: revert dynamic paths for split-usr setups 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.

man: generate configured paths in manpages 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.

man: fix a bunch of links All hail linkchecker!

login: make hold-off timeout configurable This introduces 'HoldoffTimeoutSec' to logind.conf to make IGNORE_LID_SWITCH_{SUSPEND,STARTUP}_USEC configurable. Background: If an external monitor is connected, or if the system is docked, we want to ignore LID events. This is required to support setups where a laptop is used with external peripherals while the LID is closed. However, this requires us to probe all hot-plugged devices before reacting to LID events. But with modern buses like USB, the standards do not impose any timeout on the slots, so we have no chance to know whether a given slot is used or not. Hence, after resume and startup, we have to wait a fixed timeout to give the kernel a chance to probe devices. Our timeout has always been generous enough to support even the slowest devices. However, a lot of people didn't use these features and wanted to disable the hold-off timer. Now we provide a knob to do that.

Do not advertise .d snippets over main config file For daemons which have a main configuration file, there's little reason for the administrator to use configuration snippets. They are useful for packagers which need to override settings, but we shouldn't advertise that as the main way of configuring those services. https://bugs.freedesktop.org/show_bug.cgi?id=89397

man: boilerplate unification

Reindent man pages to 2ch

man: Factor out a common snippet for .d directories and precedence Several manpages contain duplicate text describing a standard set of .d configuration directories, with the usual sorting, precedence, overrides, and so on. Factor this common text out using XInclude before proliferating it even further.

man/logind.conf.xml: Make "man logind.conf.d" work too

logind: Support logind.conf.d directories in the usual search paths This makes it possible to drop in logind configuration snippets from a package or other configuration management mechanism. Add documentation to the header of /etc/logind.conf pointing the user at /etc/logind.conf.d/*.conf. Introduce a new helper, conf_parse_many, to parse configuration files in a search path.

man/logind.conf.xml: make consistent with default logind.conf https://bugs.freedesktop.org/show_bug.cgi?id=86263

man: remove another gendered pronoun

logind: add HandleLidSwitchDocked= option to logind.conf + documentation https://bugs.freedesktop.org/show_bug.cgi?id=82485

man: logind.conf: fix grammar issues, unclear wording, and unclear default values

doc: comma placement corrections and word order Set commas where there should be some. Some improvements to word order.

logind: automatically remove SysV + POSIX IPC objects when the users owning them fully log out

logind: make $XDG_RUNTIME_DIR a per-user tmpfs This way each user allocates from his own pool, with its own size limit. This puts the size limit by default to 10% of the physical RAM size but makes it configurable in logind.conf.

logind: ignore lid switch if more than 1 display is connected Previously we expected the desktop environment to take an inhibitor lock, but this opened a race on boot-up where logind might already be running but no DE is active. Hence, let's move checking for additional displays into logind. This also opens up this logic for other DEs, given that only GNOME implemented the inhibitor logic so far.

logind: restore logic to kill user processes when session ends

man: improve word usage and grammar in logind.conf(5)

man: more grammar improvements - place commas - expand contractions (this is written prose :) - add some missing words

man: improve grammar and word formatting in numerous man pages Use proper grammar, word usage, adjective hyphenation, commas, capitalization, spelling, etc. To improve readability, some run-on sentences or sentence fragments were revised. [zj: remove the space from 'file name', 'host name', and 'time zone'.]

man: fix some typos

build-sys: do not install logind manpages when disabled The condition was wrong: HAVE_PAM -> ENABLE_LOGIND.

man: clarify how to configure default control group hierarchies for services and sessions

man: rename systemd.conf to systemd-system.conf Alias as systemd-user.conf is also provided. This should help users running systemd in session mode. https://bugzilla.redhat.com/show_bug.cgi?id=690868

build-sys: create Makefile-man.am automatically man rules were repeating the same information in too many places, which was error prone. Those rules can be easily generated from .xml files. For efficiency and because python is not a required dependency, Makefile-man.am is only regenerated when requested with make update-man-list If no metadata in man/*.xml changed, this file should not change. So only when a new man page or a new alias is added, this file should show up in 'git diff'. The change should then be committed. If the support for building from git without python was dropped, we could drop Makefile-man.am from version control. This would also increase the partial build time (since more stuff would be rebuild whenever sources in man/*.xml would be modified), so it would probably wouldn't be worth it.

man: document logind's IdleAction= and IdleActionSec=

logind: add 'lock' as possible choice for handling hw keys

man/logind.conf.xml: Add missing 'suspend' value for Handle*Key options.

logind: support for hybrid sleep (i.e. suspend+hibernate at the same time)

logind: split up HandleSleepKey= into HandleSuspendKey= and HandleHibernateKey= The kernel and X11 distuingish these two, and Thinkpad keys have both, hence we really should distinguish them too.

logind: rework power key/suspend key/lid switch handling http://lists.freedesktop.org/archives/systemd-devel/2012-September/006604.html https://bugzilla.gnome.org/show_bug.cgi?id=680689 This changes the meaning of the HandlePowerKey=/HandleSleepKey=/HandleLidSwitch= setting of logind.conf

logind: make sure there's always a getty available on TTY6 Previously, if X allocated all 6 TTYs (for multi-session for example) no getty would be available anymore to guarantee console-based logins. With the new ReserveVT= switch in logind.conf we can now choose one VT (6 by default) that will always be subject to autovt-style activation, i.e. we'll always have a getty on TTY6, and X will never take possession of it.

man: reword logind.conf.xml a bit

docs: typo fixes in logind.conf.xml and os-release.xml https://bugs.freedesktop.org/show_bug.cgi?id=54501

man: document systemd-journal

man: write man page for systemd-logind

logind: rework button setting semantics If a graphical session without full DE that handles power/suspend events is used this can now be controlled by logind instead, optionally.

logind: optionally handle power, sleep and lid switch events This takes handling of chassis power and sleep keys as well as the lid switch over from acpid. This logic is enabled by default for power and sleep keys, but not for the lid switch. If a graphical session is in the foreground no action is taken under the assumption that the graphical session does this.

logind: use "sleep" as generic term for "suspend", "hibernate", and later on "hybrid suspend"

logind: implement delay inhibitor locks in addition to block inhibitor locks This is useful to allow applications to synchronously save data before the system is suspended or shut down.

relicense to LGPLv2.1 (with exceptions) We finally got the OK from all contributors with non-trivial commits to relicense systemd from GPL2+ to LGPL2.1+. Some udev bits continue to be GPL2+ for now, but we are looking into relicensing them too, to allow free copy/paste of all code within systemd. The bits that used to be MIT continue to be MIT. The big benefit of the relicensing is that closed source code may now link against libsystemd-login.so and friends.

rename /etc/systemd/systemd-{login,journal}d.conf to {login,journal}d.conf
