* man: explain allowed values for /sys/power/{disk,state}Zbigniew Jędrzejewski-Szmek2023-05-171-24/+31
| | | | | | | Also fix the grammar: "neither" can only be used with two values, and here we have an inderminate number >= 1. Fixes #26460.

* sleep: introduce SuspendEstimationSec=Yu Watanabe2023-01-271-28/+30
| | | | | | | | | | | | | | | | | | | Before v252, HibernateDelaySec= specifies the maximum timespan that the system in suspend state, and the system hibernate after the timespan. However, after 96d662fa4c8cab24da57523c5e49e6ef3967fc13, the setting is repurposed as the default interval to measure battery charge level and estimate the battery discharging late. And if the system has enough battery capacity, then the system will stay in suspend state and not hibernate even if the time passed. See issue #25269. To keep the backward compatibility, let's introduce another setting SuspendEstimationSec= for controlling the interval to measure battery charge level, and make HibernateDelaySec= work as of v251. This also drops implementation details from the man page. Fixes #25269.

| | | | | | | For users, the square brackets already serve as markup and clearly delineate the section name from surrounding text. Putting additional markup around that only adds clutter. Also, we were very inconsistent in using the quotes. Let's just drop them altogether.

* man: move all config file options to one sectionZbigniew Jędrzejewski-Szmek2019-02-131-1/+1
| | | | | | We had "SYSTEM MANAGER DIRECTIVES" which was a misnomer already, because it also listed user manager stuff. Let's make this a more general section and move the items for other services there too (from "MISCELANENOUS").
* shared/sleep-config: add switches to kill specific sleep modesZbigniew Jędrzejewski-Szmek2018-10-081-0/+18
| | | | | | | | | | | | /etc/systemd/sleep.conf gains four new switches: AllowSuspend=, AllowHibernation=, AllowSuspendThenHibernate=, AllowHybridSleep=. Disabling specific modes was already possible by masking suspend.target, hibernate.target, suspend-then-hibernate.target, or hybrid-sleep.target. But this is not convenient for distributions, which want to set some defaults based on what they want to support. Having those available as configuration makes it easy to put a config file in /usr/lib/systemd/sleep.conf.d/ that overrides the defaults and gives instructions how to undo that override.

| | | | | | | | | | | | | | | | | | | | | | | | Docbook styles required those to be present, even though the templates that we use did not show those names anywhere. But something changed semi-recently (I would suspect docbook templates, but there was only a minor version bump in recent years, and the changelog does not suggest anything related), and builds now work without those entries.

* tree-wide: beautify remaining copyright statementsLennart Poettering2018-06-141-1/+1
| | | | | | Let's unify an beautify our remaining copyright statements, with a unicode ©. This means our copyright statements are now always formatted the same way. Yay.
* tree-wide: drop 'This file is part of systemd' blurbLennart Poettering2018-06-141-2/+0
| | | | | | | | | | | | | | | | This part of the copyright blurb stems from the GPL use recommendations: https://www.gnu.org/licenses/gpl-howto.en.html The concept appears to originate in times where version control was per file, instead of per tree, and was a way to glue the files together. Ultimately, we nowadays don't live in that world anymore, and this information is entirely useless anyway, as people are very welcome to copy these files into any projects they like, and they shouldn't have to change bits that are part of our copyright header for that. hence, let's just get rid of this old cruft, and shorten our codebase a bit.
* man: add a new page with a general description of common syntaxZbigniew Jędrzejewski-Szmek2018-04-181-1/+4
| | | | | | | | We have a common parser, but for the user it might be completely unobvious that the same general rules apply to all those files. Let's add a page about the basic syntax so that the more specific pages don't have to repeat those details.
* tree-wide: drop license boilerplateZbigniew Jędrzejewski-Szmek2018-04-061-13/+0
| | | | | | | | | | Files which are installed as-is (any .service and other unit files, .conf files, .policy files, etc), are left as is. My assumption is that SPDX identifiers are not yet that well known, so it's better to retain the extended header to avoid any doubt. I also kept any copyright lines. We can probably remove them, but it'd nice to obtain explicit acks from all involved authors before doing that.
* Rename suspend-to-hibernate to suspend-then-hibernateMario Limonciello2018-03-281-5/+5
| | | | | Per some discussion with Gnome folks, they would prefer this name as it's more descriptive of what's happening.
* Introduce suspend-to-hibernate (#8274)Mario Limonciello2018-03-081-5/+28
| | | | | | | | | | | | | | Suspend to Hibernate is a new sleep method that invokes suspend for a predefined period of time before automatically waking up and hibernating the system. It's similar to HybridSleep however there isn't a performance impact on every suspend cycle. It's intended to use with systems that may have a higher power drain in their supported suspend states to prevent battery and data loss over an extended suspend cycle.

* man: revert dynamic paths for split-usr setupsTom Gundersen2015-06-181-8/+5
| | | | | | | | | | | | | | | | | | | | | | | 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 manpagesFilipe Brandenburger2015-05-281-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | 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

* systemd-sleep: add support for freeze and standbyZbigniew Jędrzejewski-Szmek2013-05-061-0/+181
A new config file /etc/systemd/sleep.conf is added. It is parsed by systemd-sleep and logind. The strings written to /sys/power/disk and /sys/power/state can be configured. This allows people to use different modes of suspend on systems with broken or special hardware. Configuration is shared between systemd-sleep and logind to enable logind to answer the question "can the system be put to sleep" as correctly as possible without actually invoking the action. If the user configured systemd-sleep to only use 'freeze', but current kernel does not support it, logind will properly report that the system cannot be put to sleep. https://bugs.freedesktop.org/show_bug.cgi?id=57793 https://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=7e73c5ae6e7991a6c01f6d096ff8afaef4458c36 http://lists.freedesktop.org/archives/systemd-devel/2013-February/009238.html SYSTEM_CONFIG_FILE and USER_CONFIG_FILE defines were removed since they were used in only a few places and with the addition of /etc/systemd/sleep.conf it becomes easier to just append the name of each file to the dir name.
