I don't know how you build the stuff, but yes the above is a solution. Furthermore, apart from the initrd, both the kernel and the needed files will soon be available as .udeb, so you could add that to extract them and build the initrd, in a way similar to what the debian-installer does. Not sure if this approach would be usefull for you. The initrd is normally generated at kernel-image installation time, but you are going to generate it yourself.

How is /usr/lib/kernel-image-version generated? It is contained in the kernel-image, together with the modules and the kernel, so you just get them at the same time. Eventually, you unpack the kernel-imahe somewhere, and use it to get the kernel, to get the modules while building the initrd, and to run mkvmlinuz on it. > > Also, do you have also the sources of the modified powerpc packages ? > > What packages? The kernel is the Debian kernel. The Config is on the image.

Maybe, not sure. I am just saying that Apple is damn stupid to do frnech ibook keyboard without tilda, pipe or backslash (and i am probably missing a few others). It may still be a mkisofs problem, but i don't see how you could deduct that from the above three lines :) > > Why not add those modules to the initrd and have it loaded, like the > > mkinitrd generated initrd does ?

As I mentioned in another mail, I'd like to extend the initrd > until we can use standard Debian kernels. I think not much should be needed. A way to modprobe the modules with some minimal hardware detection, and putting the modules that John would builtin in the initrd. Friendly, Sven Luther
