I just wanted to extract the USB boot image from the
.iso of the CentOS DVD image that i downloaded.
Now i mounted it by
[root@localhost ~]# mkdir /mnt/iso [root@localhost ~]# mount /home/dloads/CentOS-5.2-i386-bin-DVD.iso /mnt/iso/ -t iso9660 -o loop,ro
ro mounts it read only so that we dont accidentally make no changes.
loop is required to mount it as a loop device (so as to access the file as a block device).
