Hi,
I noticed that loop mounts are not automatically cleaned in my system. Is there any way that I can fix it?
How do you mount it (with "-o loop" or with losetup)? How do you unmount it (by giving the mountpoint, the image file or the loop device)? Is your /etc/mtab a file or is it a symbolic link to /proc/mounts?
The behaviour I know is that the loop device will *not* be freed if a) /etc/mtab is a link to /proc/mounts *or* b) you gave the loop device explicitly as umount argument *or* c) you mounted it with losetup explicitly *or* d) you used -n when mounting (so the mountpoint does not end up in mtab)
But different mount versions do it differently (busybox mount even has its own parameter for it, because embedded systems usually use the /mtab symlink).
You can always free your loop devices with losetup.
