Hi folks by accident I pasted umount ls -al /mnt/ into bash. My bad. AFAICT /proc was umounted immediately, the rest died slowly. Don't try this at home. Point is, according to the man page this command line should have triggered an error message. "umount ls -al" doesn't make sense. Do you think the command line parser could be fixed? util-linux is version 2.29.2-1+deb9u1, as included in Debian. Of course I checked the diff for umount.c between 2.29 and 3.34-rc2. Apparently the getopt code has been improved, but I did not notice a fix for this particular problem. Thanx in advance. Keep on your good work Harri
