Hi,

I modified this a little bit. What do you think? I know, you have found a better
solution already but with this you will get the exact device filename directly
and is "more secure":

loopdev=$(cryptsetup status "$dst"  | grep "device:" | sed -e 's/.*device: *//g'
| grep "^/dev/loop" || true)


Just an idea, use what you want. :-)
