But it's not working for me, the --types option does not limit umount in any way. In the man page it says: "Indicate that the actions should *only* be taken on filesystems of the specified type." But, for example, here Suse is of type ext4 and gets mounted: # ./mount -t ext4 /suse # ./mount | grep suse /dev/sda2 on /suse type ext4 (rw,noatime,noexec,nosuid,nodev,user) Now I want to unmount all btrfs systems: # ./umount -t btrfs /suse /zero /other # ./mount | grep suse It just unmounts everything that is mentioned, the -t has no limiting effect. So it is useful only with -a.
