| 15 | # system-update-generator uses laccess("/system-update"), while a plain | |
| 16 | # ConditionPathExists=/system-update uses access("/system-update"), so | |
| 17 | # we need an alternate condition to cover the case of a dangling symlink. | |
| 18 | # | |
| 19 | # This service is only invoked if /system-update exists, i.e. if the | |
| 20 | # condition tested by system-update-generator remains true and the system | |
| 21 | # would be diverted into system-update.target again after reboot. This way | |
| 22 | # we guard against being diverted into system-update.target again, which | |
| 23 | # works as a safety measure, but we will not step on the toes of the | |
| 24 | # update script if it successfully removed the symlink and scheduled a | |
| 25 | # reboot or some other action on its own. | |
