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			`# 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 21:35:14 +02:00			`Service=systemd-udevd.service`

units/systemd-{udevd,journald}*.socket: enable DeferTrigger= Refer to d766c75acdd825abe1bcfd45406ae2e609a008b6 for the rationale behind the udevd change. systemd-journald.service conflicts with soft-reboot.target, so make sure anything surviving soft-reboot and trying to log to journal doesn't fail the socket units. 2025-05-18 02:24:38 +02:00			`DeferTrigger=yes`
