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 17:12:18 +04:00			`# This file is part of systemd.`

units: Rename systemd-udev.service to systemd-udevd.service This naming convention is more inline with other systemd daemon unit names (systemd-logind.service, systemd-localed.service etc) The companion .socket units have also been renamed, however the -trigger and -settle units keep their current name as these are not directly related to daemon process itself. 2012-07-02 23:35:14 +04:00			`Service=systemd-udevd.service`

units: remove udev control socket when systemd stops the socket unit (#4039) Mere presence of the socket in the filesystem makes udev_queue_get_udev_is_active() return that udev is running. Note that, udev on exit doesn't unlink control socket nor does systemd. Thus socket stays around even when both daemon and socket are stopped. This causes problems for cryptsetup because when it detects running udev it launches synchronous operations that really require udev. This in turn may cause blocking and subsequent timeout in systemd-cryptsetup on reboot while machine is in a state that udev and its control socket units are stopped, e.g. emergency mode. Fixes #2477 2016-08-26 01:07:58 +03:00			`RemoveOnStop=yes`
