You see, for all of our testing we've been booting the kernel off a floppy disk with an initrd and using the hard disk to store all of our files (applications, config, etc). However, that approach doesn't quite work so well when we don't actually have a Pedigree-ready system state.
So I sat down and whipped up some ISO generation scripts, which means we now have Pedigree installer CDs. However, we don't have any method to read CD disks in Pedigree yet. What started as a simple concept (Python installer) has now developed into developing drivers for the CD drive and the on-disk filesystem format.
There's nothing wrong with that, of course, but it is slightly frustrating to not be able to jump straight into testing my installation scripts on Pedigree. If you're really interested, you can check out the progress of the installation side of Pedigree.
For all those excited about the concept of a Python + ncurses installer (highly customisable too :) ), you can see the most up-to-date scripts here. Keep in mind Pedigree has some unique requirements, and I haven't documented anything at the time of posting, so you're totally on your own if you do try them out.
