			`[Unit]`
units: adjust Descriptions of various units In general, it's not very usuful to repeat the unit name as the description. Especially when the word is a common name and if somebody doesn't understand the meaning immediately, they are not going to gain anything from the repeat either, e.g. "halt", "swap". In the status-unit-format=combined output parentheses are used around Description, so avoid using parenthesis in the Description itself. 2021-06-29 09:47:53 +02:00			`Description=System Hibernation`
units: introduce new Documentation= field and make use of it everywhere This should help making the boot process a bit easier to explore and understand for the administrator. The simple idea is that "systemctl status" now shows a link to documentation alongside the other status and decriptionary information of a service. This patch adds the necessary fields to all our shipped units if we have proper documentation for them. 2012-05-21 15:12:18 +02:00			`Documentation=man:systemd.special(7)`

units: starting suspend.target should not fail when suspend is successful (#6678) and the same for hibernate.target and hybrid-sleep.target. Tested with both sucessful and unsuccessful suspends. The result of the start job was correct in both cases. Closes #6419 (a regression in v233 and v234). > suspend is unsual for a target, because it has to stop itself once it's > started. Otherwise you couldn't start it again, so you could only suspend > once! Currently that's implemented using BindsTo=systemd-sleep.service. > Meaning it pulls in systemd-sleep.service to do the actual suspend, and > then de-activates afterwards. But the behaviour of BindsTo was changed > recently (not without some issues during development) - maybe this bug > is caused by poettering/systemd@631b676 which I think was added in > release v233. > > sleep.target (see man systemd.special) has the same need, but it > implements it differently. It simply has StopWhenUnneeded=yes. This commit switches suspend.target etc. to the approach used by sleep.target. 2017-08-30 17:20:23 +01:00			`Requires=systemd-hibernate.service`
units: rename halt/hibernate/kexec/poweroff/reboot/suspend to systed-xxx These service units also execute our own code, hence rename the accordingly and prefix them with systemd- 2012-06-25 14:24:56 +02:00			`After=systemd-hibernate.service`
