There have been few cases where v3 key file and v2 losetup/mount were used
to set up a file system, and after upgrade to v3 losetup/mount, mounting the
file system failed. There is a warning about this problem in loop-AES README
file, but not everyone reads README files.

May I suggest adding a check that losetup is recent enough. Something like
this:

    strings /sbin/losetup | grep -q -s multi-key-v3
    if [ $? != 0 ] ; then
        echo "too old losetup version"
    fi
