Reopening this because although the autopkgtests have managed to pass,
the test is still racy and we aren't correctly capturing the error
message; we were grepping for 'loop deleted:' but the actual message (as
shown in the bug log) is 'loop deleted : /dev/loop0'.

Fix is inbound.

** Changed in: livecd-rootfs (Ubuntu Zesty)
       Status: Fix Released => In Progress

** Also affects: livecd-rootfs (Ubuntu Xenial)
   Importance: Undecided
       Status: New

  [Impact]

  * Having a working autopkgtest simplifies testing of future changes including
    package SRUs thus backporting both the new autopkgtest test and the fix
    making it succeed on every architecture seems to be beneficial.
    (SRU-ing the test was suggested here: https://code.launchpad.net/~rbalint/livecd-rootfs/livecd-rootfs-autopkgtest/+merge/322322/comments/845316 )

  [Test Case]

  * Run the autopkgtest test itself. It also covers the parts needed to be
    changed for making the test pass, including the part changed in this bug.

  [Regression Potential]

  * Livecd-rootfs scripts had to be changed to make the autopkgtest test pass.
    The changes could make livecd-rootfs generate broken/invalid images, but
    this is highly unlikely because changes with regressions would also break
    the test.
