# amountcd.sh
# A simple script for mounting cdrom disc automatically when insert disc.
# It poll cdrom every 2 seconds just like "HAL" and "Udisks" do.
# But it can't take advantage of newer SATA ATAPI hardware which
# supports Asynchronous Notification(AN), see: "man hal-disable-polling".
# Usage: copy it as "/usr/local/bin/amountcd.sh", and
# "chmod +x /usr/local/bin/amountcd.sh", add it into "/opt/bootlocal.sh"
# or some where else, for example: "/usr/local/bin/amountcd.sh &"
# I have tested it on tinycore-3.7.1 and tinycore-4.1 ok.

PATH="/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin"

# Read a list of CDROM/DVD Drives
CDROMS=""
CDROMSF=/etc/sysconfig/cdroms
[ -s "$CDROMSF" ] &&  read CDROMS < "$CDROMSF"

for cdrom in $CDROMS
do
  FSTYPE="$(fstype $cdrom)"
  devname=`echo $cdrom | sed "s@/dev/@@"`
  if [ -z $FSTYPE ]
  then
    eval sta_$devname="0"
  else
    eval sta_$devname="1"
  fi
  #eval echo "first sta_$devname=\${sta_$devname}"
done

while [ 1 ]
do
  sleep 2s
  #echo "******************"
  for cdrom in $CDROMS
  do
    FSTYPE="$(fstype $cdrom)"
    devname=`echo $cdrom | sed "s@/dev/@@"`
    if [ -z $FSTYPE ]
    then
      eval stb_$devname="0"
    else
      eval stb_$devname="1"
    fi
    #eval echo sta_$devname=\${sta_$devname}
    #eval echo stb_$devname=\${stb_$devname}
    eval sta=\${sta_$devname}
    eval stb=\${stb_$devname}
    if [[ "$sta" == "0" -a "$stb" == "1" ]]
    then
      mount $cdrom
      #echo "mount $cdrom ok"

Todo: It can't detect audio CD inserting and mount it with "-t cdfs", any idea?

Hi littlebat

If there is no disc in the drive, no file is created.
If there is an audio disc in the drive, an empty file is created.
If there is a data disc in the drive, a 512 byte file is created.
Or you can set of=/dev/null and parse the output of /bin/dd.

gerald_clark:
Try 'blkid /dev/sr0'

Rich:
Hi gerald_clark
He is also trying to detect if the disc is an audio CD. I tried that command and it doesn't return
anything for an audio CD.

gerald_clark:
You can't mount audio CDs, and I am not aware of any CDfs for core.
