If I change the content of the ext3fs.img can I put it back on the rw mounted squashfs.img and that in the iso?
Answering myself: no.
The procedure I used now is in short: unsquashfs the squashfs.img add a few files to the home dir on ext3fs.img, just for testing mksquashfs the new squashfs.img from the squashfs-root tree extract all stuff from the iso to a directory tree, replace the squashfs.img with the new one. Then mkisofs the directory to a new iso. Seems to has worked just fine. The resulting CD looks the same as the original one, just with additional translation tables and a slightly bigger squashfs.img.
Problem: at boot the kernel finally panics because of a problem with initrd. It "can't find root file system" and drops me to a shell. Why would I need a new initrd if I just add a few static files?
