|  | # 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. |
