A script to mount available CD/DVD Drive on system boot automatically ?

Now we will look how to mount a CD/DVD rom drive on Linux/Unix drive automatically on system reboot.

We can use the below command/script in /etc/profile or /etc/rc.sysinit or similar startup script in /etc/rc*/d.

[root@nglinux]# mkdir -p /tmp/cdrom; for i in hda sr0 scd0; 
do mount -t iso9660 /dev/$i /tmp/cdrom && break; done
mount: special device /dev/hda does not exist
mount: block device /dev/sr0 is write-protected, mounting read-only

Verify the mountpoint if it is mounted correctly.

[root@nglinux]# df -h /tmp/cdrom
Filesystem      Size  Used Avail Use% Mounted on
/dev/sr0        1.7G  1.7G     0 100% /tmp/cdrom
[root@nglinux ks]# 

Now you can observe that the cdrom is mounted.

The command tries to mount different drives in /dev/ directory and as soon it finds the correct drive, it breaks the loop and exit.

It will not mount other drives since they are not of iso9660 type.
