 # This script is able to disable and enable automounting for a device.
 # It's usage is as follows:
 #
 #   k3b_automount disable /dev/cdrom
 # or
 #   k3b_automount enable /dev/cdrom
 #
 # /dev/cdrom needs to have an entry in /etc/fstab.
 # 
 # The supported automounting systems are subfs and supermount.
 #
 # Exit codes:
 #   0 - success
 #   1 - wrong usage
 #   2 - device not configured with subfs/supermount in /etc/fstab
 #   X - failed to mount/umount
 #

 # fix the problem with DVD+RW burning which may be mounted once the burning has
 # been started.

 # So we unmount the device in case it is mounted with iso9660 or udf (just to add
 # some security to this suid script. :(
