Ah :-(

¿Is that a bug I should report in bugzilla?

And the missing "/sbin/mount.xfs"? What is that?

I have plain non encripted dvds, iso...something. They certainly work via 
normal plain mount. And the encripted ones work well via the crypto 
compatibility thing, which you know means that I can't use newly created 
crypto filesystems that use a diferent module (twofish256 vs 
CryptoAPI/twofish-cbc), using plain mount.

I also have a concoction of zisofs compressed and xfs encripted 
filesystems, but that one is complex to test (it worked last time I tried 
some months back).

I have no idea how to mount plain dvds using the device map thing, which 
is totally new stuff to me. Do you know a howto somewhere? Man pages 
assume you already know what you are looking for, too terse and useless in 
this case.
