  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.
