I stand to be corrected, but as far as I know, files on a mounted loopback iso are only symlinks to the actual files. If this is the case, is there any way to copy the actual files onto a separate folder? There's a Mandrake howto here
http://www.theory.physics.ubc.ca/mandrake-update.html, but it's rather dated. I'm going to give it a try and I'm still searching on Google, but I would appreciate suggestions from anyone who's been able to copy files from a loopback iso before. Thanks.
