Hi, Trying to umount it.
util-linux is acting weird, while busybox is doing fine.
tc@box:/tmp$ sudo su
root@box:/tmp# umount /mnt/sr0/
umount: /mnt/sr0: must be superuser to unmount.
root@box:/tmp# echo $?
32
root@box:/tmp# df | grep sr0
/dev/loop166 27698 27698 0 100% /mnt/sr0
root@box:/tmp# busybox.suid umount /mnt/sr0/
root@box:/tmp# echo $?
0
P.S. mounted with both version, both can be umounted with busybox, but not util-linux.
