Re: Persistent=cryptsetup

["marcosestevesbarbosa@gmail.com" <marcosestevesbarbosa@gmail.com>]

I say you need to use (manually) the commands to format a encrypted partition (and set the password):
cryptsetup luksFormat <device>
mkfs.ext2 ...
Maybe is a good idea include this commands inside initramfs. The secret is use the command:

cryptsetup isLuks <device>
if the <device> is luks formated, return zero code. If not formated, return 234 code.
The basically idea is: If is the first use of the system, isLuks return 234 and system show a prompt to set the password. If not, isLuks return zero and just show prompt to enter the password and mount the device.

Understand?
Thanks.

I must admit I don't understand what your are meaning with "pre-format
the partition to work with cryptsetup". Do you really want to set the
encryption passphrase at image build time?
