add initrd-fs.target and root-fs.target Instead of using local-fs*.target in the initrd, use root-fs.target for sysroot.mount and initrd-fs.target for /sysroot/usr and friends. Using local-fs.target would mean to carry over the activated local-fs.target to the isolated initrd-switch-root.target and thus in the real root. Having local-fs.target already active after deserialization causes ordering problems with the real root services and targets. We better isolate to targets for initrd-switch-root.target, which are only available in the initrd.

Description=Initrd Default Target
add initrd-fs.target and root-fs.target Instead of using local-fs*.target in the initrd, use root-fs.target for sysroot.mount and initrd-fs.target for /sysroot/usr and friends. Using local-fs.target would mean to carry over the activated local-fs.target to the isolated initrd-switch-root.target and thus in the real root.

We better isolate to targets for initrd-switch-root.target, which are only available in the initrd.

Documentation=man:systemd.special(7)
Revert "units: drop OnFailure= from .target units" 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.

Make initrd.target the default target in the initrd First, rename root-fs.target to initrd-root-fs.target to clarify its usage. Mount units with "x-initrd-rootfs.mount" are now ordered before initrd-root-fs.target. As we sometimes construct /sysroot mounts in /etc/fstab in the initrd, we want these to be mounted before the initrd-root-fs.target is active. initrd.target can be the default target in the initrd.

Requires=basic.target
Create initrd-root-device.target synchronization point (#3239) Add a synchronization point so that custom initramfs units can run after the root device becomes available, before it is fsck'd and mounted. This is useful for custom initramfs units that may modify the root disk partition table, where the root device is not known in advance (it's dynamically selected by the generators).
