I successfully ran the test case with the packages from -proposed. The VM also still boots successfully and shows no other sign of trouble.

This feature was introduced in Linux 3.1 already (i. e. before precise even). This is a showstopper for backporting snappy as that needs a lot of loop mounts. Support for loop-control got introduced later util-linux versions, but backporting full support for it (for losetup) is too intrusive. We only need a partial backport for "mount -o loop". SRU TEST CASE: First, use up all default 8 loop devices: $ for i in `seq 8`; do echo $i; sudo losetup --find /etc/issue; done Now try to use a 9th: $ dd if=/dev/zero of=/tmp/img bs=1M count=50 $ mkfs.ext2 -F /tmp/img $ sudo mount -o loop /tmp/img /mnt With current trusty's "mount" package this will fail with "could not find any free loop device". With the proposed version, this should succeed, and "sudo losetup -a" should show "/dev/loop8: ... (/tmp/img)". Now, reboot, disable loop-control with sudo mv /dev/loop-control{,.disabled} and run the test case again. Now "mount -o loop" should fail with "could not find any free loop device" (as before). Ensure that there are no hangs, infinite loops, etc. REGRESSION POTENTIAL: /dev/loop-control and the corresponding util- linux support has exited for a long time without known/major issues, so this should be fairly safe. Also, the patch falls back to the previous "iterate over loop0 to loop7" behaviour if loop-control is not available.
