i agree with you, only it would be useful for providing a timeout
function in cryptdisks. but when the patch for cryptsetup is accepted by
clemens, that is quite a better solution.

ok, so either we should improve luksformat to support fs images, or
grml-crypt needs to be restricted to exactly that. i don't know what you
think, but i gues that luksformat is a cleaner implementation.

yes, it's a workaround. i'dd prefer a clean implementation, best would
be to have dm-crypt support in mount ;-)
nevertheless grml-crypt is a handy script, and i believe that it's very
useful for your grml distribution.
