Linux : Creating virtual disks from .iso files

Just picked this up from the fedora guide and and thought I might put it here for reference.

Suppose you have a .ISO file whose contents you wish to examine or even need to copy some data out of. The fedora-guide suggests the following approach.

mkdir ~/your_disc/
su -c 'mount file.iso ~/your_disc -t iso9660 -o loop'

then to unmount it

su -c 'umount ~/your_disc/'
