Hi,

I followed the following steps to set up encrypted volumes with LUKS and it
works fine:

I'd like to use keyfile to automount a luks encrypted volume.  I tried to
added the line "lvmcrypt /dev/vda2 /etc/mykeyfile luks" to /etc/crypttab,
then run "mkinitfs" to regenerate initramfs, but it doesn't work.
Still prompts for passphrase :(  Anyone has idea to how to?  Thanks.

Regards,
Dave
