Er, could you do an ls -ld /etc/mtab? That looks like /proc/mounts, not
the userland created /etc/mtab.
-rw-r--r-- 1 root root 371 2007-06-27 14:29 /etc/mtab
It's just an ordinary file.
Or it could be that the fuse wrapper doesn't do the right thing, I
haven't tested any fuse filesystem, just standard iso.
You're right again! When unmounting a standard iso, the loop device gets freed.
