mkreiserfs seems not to work on plain files, which is pretty bad if you want to make a loopback-file with reiserfs.
# dd if=/dev/zero of=loopfile count=100k
# mkreiserfs -f loopfile
mkreiserfs, 2001 - reiserfsprogs 3.x.0jmkreiserfs: loopfile is not a block
special device.
Forced to continue, but please confirm (y/n)y
# mkdir mountpoint
# mount loopfile mountpoint -oloop -t reiserfs
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
or too many mounted file systems
