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. 2013-03-05 02:01:05 +08:00			`# This file is part of systemd.`

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.
