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 13:12:18 +00:00			`# This file is part of systemd.`

systemd: do not enable udev-settle.service by default This barrier service is usually not enabled by default. If enabled, it acts as a barrier for basic.target -- so all later services will wait for udev completely finishing its coldplug run. It might be enabled just unconditionally, or pulled-in on-demand by broken or non-hotplug-aware services that assume a fully populated /dev at startup. 2011-03-28 23:14:53 +00:00

systemd: update service files for newly introduced DefaultDependencies= option This new option has been introduced very recently in systemd and needs to be unset for udev, since udev is supposed to be run on early boot. 2010-07-04 02:16:14 +00:00			`DefaultDependencies=no`
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 19:35:14 +00:00			`Wants=systemd-udevd.service`

units: order all udev services before sysinit.target, too Not that it would matter much, but let's make things a bit more systematic: early boot services shall order themselves before sysinit.target, and nothing else. 2013-03-25 20:22:52 +00:00			`Before=sysinit.target`

units: drop full paths for utilities in $PATH This makes things a bit simpler and the build a bit faster, because we don't have to rewrite files to do the trivial substitution. @rootbindir@ is always in our internal $PATH that we use for non-absolute paths, so there should be no functional change. 2019-12-18 08:14:57 +00:00			`ExecStart=udevadm settle`
