This reverts commit c7220ca8025e8dbded36131b23a502d975c45754. The removal was done as a reaction to the messages from systemd: initrd-root-fs.target: Requested dependency OnFailure=emergency.target ignored (target units cannot fail). initrd.target: Requested dependency OnFailure=emergency.target ignored (target units cannot fail). initrd-root-device.target: Requested dependency OnFailure=emergency.target ignored (target units cannot fail). initrd-fs.target: Requested dependency OnFailure=emergency.target ignored (target units cannot fail). local-fs.target: Requested dependency OnFailure=emergency.target ignored (target units cannot fail). ... But it seems that the messages themselves are wrong, and the units were OK.
