9e5f0f9291 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.

                             (normal startup)
                                    :

700e07ffd5 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.

cf84347794 initrd: add unit files needed for basic systemd-in-initrd support
This will:
 * mount all configured filesystems (typically the rootfs on /sysroot)
 * reload the configuration to pick up anything from the mounted fs (typically
   /sysroot/etc/fstab)
 * mount any newly configured filesystems (typically /usr on /sysroot/usr, if
   applicable)
 * shut-down and clean-up any daemons running in the initramfs (typically udevd)
 * switch-root to /sysroot and start the real init

For an example of what files should be included in an initramfs based on this
