Hi,
no :) loop2 is the decrypted device.
A small example:
/dev/sda1 is encrypted. Then you run losetup with some options and /dev/sda1, enter
the password and after that /dev/loop1 will be created.
>From now on you're using /dev/loop1 as your device node, e.g.
fdisk -l /dev/loop1
If you would use /dev/sda1 instead you would just see garbage, because of the
encryption :)
Regards,
Felix
