Editing ISO’s in Linux

May 29, 2009

I’m building a custom Live CD for a friend, it’s basically an automated custom Linux installer. Anyhow, after the disc has been created, I needed some files on the ISO filesystem (not inside the squashfs filesystem). There’s a program for windows called Power ISO I think, that can do this, but I wanted to do it in Linux.

Turns out, Andrew Smith has written an app called ISO Master. I guess it was originally Linux only, but he now offers a Windows port as well. Editing the ISO image using his application is a piece of cake. You can even edit text files inside the ISO on the fly (great for poking at the syslinux.cfg, for example). It’s the perfect open source app; it work well, does what it advertises, and doesn’t try to do a bunch of other things.

According to his web site, he charges $20 for the Windows version, but the Linux version is free of charge. If you’re in the market to muck around with ISO’s (putting your serial number on a CD, for example) I’d highly suggest you check ISO Master out.
