This is almost exactly how I put together my uwoody stuff with uClibc. For stage 1 I used buildroot. For stage 2 I hacked up a _ton_ of packages to break circular dependancies until I had built a sufficient core of stuff that the system became usable. I built everything by hand so stage 2 was very labor intensive. By stage 3 I was able to rebuild almost everything (including the packages I had formerly hacked) using stock debian source. > How do you plan to compile coreutils for example?

The single most difficult task I had during stage 2 was trying to satisfy the dependancies of and build roughly 100 different documentation utility packages. This proved to be a surprisingly large amount of work. I consider separating documentation from binaries an essential task to get debian embedded bootstrapped from source, -Erik -- Erik B.
