Ah so, yep, that's not correct. Interesting that it write error on my
gentoo system but not on other distros...

I think attached patch could be merged to upstream too?

Anyway, the Live CD supporting cryptsetup probably should load dm_mod too
by default (target modules, like dm_crypt, are then loaded automagically).
