Thanks for that explanation.

Ah, I haven't tried it with the one that was uploaded to unstable
yet.... will give it a try later.


Another thing. Perhaps you've seen my post where I've unfortunately
overridden an (important ;) ) ext3 fs with mkfs, instead of doing fsck.

Of course this is my fault but do you see any chance to add checks to
mke2fs whether any known fs/partition type/other containter like
luks/mdadm/etc. is on the device? (And of course require a
--force=I-really-know-what-I-do™ parameter to the evil.)

Cheers,
Chris.
