If anyone is interested, I've being doing exactly this recently, i.e.
building a cf based linux distribution. Its built around the cqure
linux wireless access point distribution/build system. I've gotten to
the stage where I think I know what I'm doing, so I've stopped and I'm
documenting how I got this far. Its for work so I'm being paid to do it
:) I'm using M10000 boards.
