Just to let you know: when /etc/mtab is a symlink to /proc/mounts, loop devices aren't freed by umount and the system may run out of loop devices (which makes things worse than they were with old-style mtab). Apparently, it's not a bug, as it's documented in mount(8):
If you are not so unwise as to make /etc/mtab a symbolic link to /proc/mounts then any loop device allocated by mount will be freed by umount. You can also free a loop device by hand, using `losetup -d', see losetup(8). -- /Dmitry <ledes...@gmail.com> -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
