You really want to use XFS for an initrd??

<fx tests:>

# dd if=/dev/zero of=disk bs=1024 count=8192
# mkfs.xfs disk
# mount -oloop disk /mnt
# df /mnt
Filesystem           1k-blocks      Used Available Use% Mounted on
/root/disk                3392        32      3360   1% /mnt

OK you could tune that up a bit but I think ext2 is more approriate for an
initrd and the ext2 utils don't take up /that/ much space: probably much less
than your XFS journals in fact :-)
