Yes. > If you want to modify files don't you have to create a whole new > image? Yes. "Edit an ISO image" comprises the following steps. 1. Mount the ISO image[*]. 2. Copy the tree of files to a read-write filesystem. 3. Change the files in the read-write filesystem. 4. Create a new ISO image from the read-write filesystem. [*] IIRC, there are utilities that allow you to combine steps 1-2 into a single step: "Extract files from ISO image into a read-write filesystem". But, I can't ever remember how to do that, so I just do the two steps. -- Grant Edwards grant.b.edwards Yow!
