thanks it mount the iso file by adding the entry into the /etc/fstab. One last thing which i want to discuss is when we manually mount the iso file
# mount -o loop centos.iso /mnt/iso
then how can i unmount it ? To unmount it i always reboot the system.Is there any way to unmount it ?
If I use
umount -o loop centos.iso /mnt/iso
umount: invalid option -- o
How can I unmount it ?
