"Do you mind taking a minute to explain what you are doing?"
A link is a reference to another file, but it only contains the location of the other file so it's small. It's the Linux equivalent of a windows shortcut file.
I wanted to tell someone how to remaster dsl 0.8.0 using a minimum amount of drive space and RAM. So at first I thought copy everything you need into the newcd directory, change the things in the boot directory you need to, use mkisofs with the billion switches you need, and you're done. The problem is you wind up with a 50 Meg newcd directory and a 50 Meg iso file.
Then I realized that I'm copying a rather large file (/cdrom/KNOPPIX/KNOPPIX), and wouldn't it be better if I could put a link to the big file in the newcd directory, and when mkisofs needed to read it, it could read it from the cdrom. It does this if you use the -f switch. Since you use the KNOPPIX file on the cdrom, you only need about half the room.
It would also be a good technique for remasterings where you only want to add an optional directory, but didn't want to burn a multisession CD. It's not good when you actually want to change things in the KNOPPIX directory.
I posted the method here
