Hey Daniel,

If at all, your request needs to be implemented in gdm. It's not only
out of cryptsetups scope to submit/forward a passphrase, it even would
be a grave security hole if it was supported.

I cannot imagine a secure implementation for your requested
functionality at all. maybe you can do something with libpam-mount.

sorry, the wishlist request is not valid for cryptsetup, thus I'm
closing the bugreport.
