+# This is to be executed by udev with the following rules:
+# CALLOUT, BUS="ide", PROGRAM="name_cdrom.pl %M %m", ID="good*", NAME="%1c", SYMLINK="cdrom" 
+# CALLOUT, BUS="scsi", PROGRAM="name_cdrom.pl %M %m", ID="good*", NAME="%1c", SYMLINK="cdrom" 
+#
+# The scsi rule catches USB cdroms and ide-scsi devices.
