Our friend piper once taught me how to use pyfll to build a custom aptosid ISO, using a current kernel, whichever DE I wanted, and selected current packages, and I wrote out the procedure as I learned it, for future use. But I only used it a couple of times -- I have good Internet service (for an American ....) and just haven't needed to do that again. I would be happy to share the procedure, but I don't know if it still works like it did in 2010.
