Thanks for replying.  However, my point is that I don't want to have to run livecd-creator again (takes time) every time I change two or three files.  I am looking to have different versions of these two or three files for each user who will be using this Live CD, and to have to run livecd-creator every time, although it would work, would take lots of time.   That's why I am searching for a way to just change the ISO directly, to modify the handful of files I wish to change and be able to re-burn the CD and boot it.  The files I wish to change are on the Live CD file system (/mnt/live), not on the squashfs OS file system.   Thanks, Todd --- On Fri, 6/27/08, Pedro Silva <pedrofsilva(a)netcabo.pt&gt; wrote: From: Pedro Silva <pedrofsilva(a)netcabo.pt&gt; Subject: Re: [Fedora-livecd-list] Modifying ISO to include per-user files To: todd655495(a)yahoo.com, fedora-livecd-list(a)redhat.com Date: Friday, June 27, 2008, 11:41 AM Hi !
