# a horribly funny script that shows how flexible udev can really be
# This is to be executed by udev with the following rules:
# CALLOUT, BUS="ide", PROGRAM="name_cdrom.pl %M %m", ID="good*", NAME="%2c", SYMLINK="cdrom"
# CALLOUT, BUS="scsi", PROGRAM="name_cdrom.pl %M %m", ID="good*", NAME="%2c", SYMLINK="cdrom"
#
# The scsi rule catches USB cdroms and ide-scsi devices.
