I setup a virtual CD-ROM server following the instructions found here. It works great, however the ISO's that are mounted never unmount automatically. In the auto.master file I've had --timeout=60 (as shown in the instructions) and --timeout 60 (as I've see on other web sites). I even removed timeout completely thinking mounts would unmount automatically after five minutes of unuse (as I've read is the default timeout). I can't figure out why the images don't unmount. This hasn't caused any problems yet, and everything else is working fine, but i would like to know if there is something I did wrong or something the instructions did not cover for my distro. Anyone have any ideas?
