Optimize the scripts reflecting the now more powerful rule logic,
cause we can combine all known fields now in any order:
The ide-devfs.sh is only executed if the kernel name matches with 'hd*':
BUS="ide", KERNEL="hd*", PROGRAM="/etc/udev/ide-devfs.sh %k %b %n", NAME="%k", SYMLINK="%1c %2c"
The name_cdrom.pl is only executed for ide and scsi devices, but not for a partition.
It exits with nonzero to skip the rule if the CD is not found:
KERNEL="[hs]d[a-z]", PROGRAM="name_cdrom.pl %M %m", NAME="%1c", SYMLINK="cdrom"
