+# 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.
