Unmount Daemon for Fedora automatically unmounts the removable media that Fedora automatically mounts, such as CDs, DVDs, and USB disks. The daemon periodically scans for mounted devices. It ignores the mount points that are listed in /etc/fstab as well as those whose device name does not start with a slash. All other devices are unmounted. The configuration file allows you to set other devices that must not be unmounted by the daemon.
