If using a anaconda-based distribution, there are some scripts in
the
anaconda source that may provide some guidance.

Thanks for that - it doesn't *quite* do what I need (it expects a
cpio-based initrd, and mine is an ext2 FS). but that gave me enough ideas
to get things going. I'll let you know if it works :-)
