Well, after the previous discussions on how to find CD-ROMs, I figured I'd
post what I finally came up with. It works with IDE and SCSI CD's, which is
all I have to test with. It works correctly if there is more than one CD
present. It probably doesn't work with the old propriatery interface CD
drives.
no sed, no grep, nuttin' but sh...
# Locate an IDE or SSCI CD-ROM drive
unset CDDEV
for file in /proc/ide/hd?/media /proc/scsi/scsi; do
[ -r $file ] || continue
while read line ; do
case $line in
*CD-ROM*|*cdrom*)
CDDEV=${file#/proc/*/}
CDDEV=${CDDEV%/media}
[ "$CDDEV" = "scsi" ] && CDDEV=scd0
break 2
;;
esac
done <$file
done
[ -n "$CDDEV" ] && ln -sf /dev/$CDDEV /dev/cdrom
