Hi.

What's ugly about that? According to my losetup manpage:
---snip---
Print name of first unused loop device:

   losetup -f
---snap---
That's a clean solution for going through all /dev/loop* /dev/loop/* files
manually.

blindcoder@ceres:~$ mine -q util-linux
util-linux 2.12p 0

Alternatively, you can use the following bash code:

unset tmpdev
for x in /dev/loop* /dev/loop/* ; do
	[ -e ${x} ] || continue
	losetup $x 2>&1 >/dev/null || tmpdev="$x"
	[ -n "${tmpdev}" ] && break
done

Greetings,
