I am working on an ubuntu iso personalization script based on the buggy uck ..
The uck team seemed to know what they were doing, they used the structure of the ubuntu iso image a lot ..

The problem is, There are several files I can't understand, like: ISO/casper/filesystem.squashfs , and rootfs .. These files seem to be really important for customizing the environment.

That said, I need a brief explanation of the structure of linux iso images in general, and ubuntu iso in specific. Thanks ..


The idea of answering myself isn't appealing, but I'm writing this for the sake of others who viewed this question hoping they'd get an answer.

After googling, I found some interesting pages discussing the topic ..

And for Live CDs specifically ..
