let me show what i think could be easily and cleanly done.

we just check for some file, like /etc/crypttab, and if it 
exists, read it and call cryptsetup...we only support luks 
encrypted filesystems and we dont support encrypted root 
either. (who wants his root partition to be encrypted 
anyway? not much to hide here).
it wouldnt be very generic, as it doesnt support the older 
cryptoloop or something...or root encryption, but it would 
be a start, at least we support the cool stuff.

people could setup their dm-crypt stuff, edit one file 
(/etc/crypttab) and lunar will handle these at bootup.

what do you think? we could have a nice "dm-crypt on your 
lunar laptop" (whatever) howto too.

its like 20 lines of code, that just aint working....yet :P
