Package: initscripts
Version: 2.86-5
Severity: wishlist
When a loop device is used implicitly by mounting a file with the loop
option, e.g.:
mount -o loop /path/to/filesystem /mnt
the loop device is automatically released when the filesystem is
unmounted. However, when a loop device is set up and mounted
manually, e.g.:
losetup /dev/loop0 /path/to/filesystem
mount /dev/loop0 /mnt
the device is not automatically released when the filesystem is
unmounted. It must be manually released:
losetup -d /dev/loop0
I use the loop device in this way fairly often, but often forget to
release the device after use. This causes a problem when I shut my
computer down: because the file attached to the loop device is open,
the filesystem in which it resides cannot be cleanly unmounted.
I think that there is a need for a shutdown script that automatically
unmounts and releases all loop devices. I have appended the script I
use for this purpose. I installed it as /etc/init.d/releaseloop, and
it is run in runlevels 0 and 6 immediately before umountfs. I make no
claims about its robustness or suitability for Debian, only that it
Works For Me.

This bug is being closed as part of a cleanup of the old bug
reports in the sysvinit package, in an attempt to make it easier
to address the bug reports which actually are fixable. Some
reasons:
- Not a bug and/or it's a patch which will not be applied
- It will not be fixed, ever for various reasons
- Problem is not fixable in sysvinit or not our responsibility
- A better solution has become available in the interim
- No activity or submitter response in over a decade or more
