I've had it up and running without problems. It's a little brain-bending
at times, but seems to work well.

# dd if=/dev/zero bs=1M count=1 seek=1000 of=reiser4test
# losetup /dev/loop1 reiser4test
# /usr/local/sbin/mkfs.reiser4 /dev/loop1
# mount -t reiser4 /dev/loop1 /mnt/tmp

I wouldn't keep real data on it or run my root FS off it or anything
yet, though. It could also use some more documentation on getting ACLs,
xattrs, streams (yes, streams) etc working.

Of course, most of the "interesting" bits are currently accessed via the
reiser4() syscall.
