Hi ,

Trying to clearly understand what you want to do.
Are you looking for an installer or something like a live CD ?

Debian and Ubuntu are much easier to make installers for.
The Gentoo installer uses squashfs. This is something that I never got into.
You would have to have an understanding of booting with the squashfs as well as a kernel with support for it as well as aufs support. also you would need to redo the boot initrd into a Uboot compatible ramdisk with any essential drivers (eg video) compiled as modules and embedded into the new ramdisk. Daz and Pat Wall may be able give you some pointers re squashfs .
The Sam440ep also has some size limitation in ramdisk size and the kernel has some restrictions in the size which can restrict some drivers from being builtin. If squashfs support needs to be built to work and results in the maximum kernel size being exceeded then you are stuck .

I have the kernel, the squashfs, ub2lb/parthenope, those are easier to create
what I need is the actual mkisofs command that will generate the actual bootable cd.
