[Unit] Description=Remove the Offline System Updates symlink Documentation=man:systemd.special(7) man:systemd.offline-updates(7) After=system-update.target DefaultDependencies=no Conflicts=shutdown.target Before=shutdown.target SuccessAction=reboot # system-update-generator uses laccess("/system-update"), while a plain # ConditionPathExists=/system-update uses access("/system-update"), so # we need an alternate condition to cover the case of a dangling symlink. # # This service is only invoked if /system-update exists, i.e. if the # condition tested by system-update-generator remains true and the system # would be diverted into system-update.target again after reboot. This way # we guard against being diverted into system-update.target again, which # works as a safety measure, but we will not step on the toes of the # update script if it successfully removed the symlink and scheduled a # reboot or some other action on its own.
