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: bind udev control socket in systemd and split udev.service We should bind the udev socket from systemd, so we are sure that the abstract namespace socket is always bound by a root process and there is never a window during an update where an untrusted process can steal our socket. Also split the udev.service file, so that the daemon can be updated/restarted without triggering any coldplug events. 2011-03-23 15:40:23 +00:00			`[Unit]`

man: refer to udevd by its service name not binary name Since the binary name is now hidden away in /usr/lib/ the primary user handle for the udev service is the unit name, hence change the man page to be available under the unit name, and make the binary name an alias for it. 2012-06-22 08:38:40 +00:00			`Documentation=man:udev(7) man:systemd-udevd.service(8)`
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			`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 service(s) before udevd, not udev-trigger (coldplug) Since hotplugs happen as soon as udevd is started, there is not much sense in giving udev-trigger an After= dependency on any service. The device could be hotplugged before coldplug starts. This is intended to avoid the race window where we create the hwdb with the wrong selinux context (then fix it up afterwards). https://github.com/systemd/systemd/issues/3458#issuecomment-322444107 2017-08-15 13:22:44 +00:00			`After=systemd-udevd-kernel.socket systemd-udevd-control.socket`

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 trigger --type=subsystems --action=add`
