Subject: [PATCH] rootfs-block/module-setup.sh: add support for xfs / reiserfs
separate journal device
xfs and reiserfs (among other) supports storing journal data to a
separate device. Unfortunately, XFS requires this information to boot
properly (reiserfs can embed the information in its metadata but you
might want to override it).
