I, too, am looking for a way to make little “tweaks” to the finished product.


I have tried mounting the ISO as loop, but after I unsquash the root filesystem to a temporary directory, I can’t seem to figure out what to do with the ext3.img file.  It seems like I should be able to mount that as a loop device, but I get an error when I try.   Does anyone have the secret decoder ring for that file?


Many thanks,

Rhonda Kern

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.
