My experiences with Angstrom were very bad. I've been using Debian since the mid 90's off and on, and I did not know where anything was on Angstrom. Couple that with the the fact that stuff like dropbear would get a corrupted file related to ssh and not let you in . . .yeah I just got rid of it so . . .
After I shook my Debian "rust" off, I was able to very quickly use Roberts instructions to cross compile my own kernel, used his barefs rootfs, and had a system running in less than 100M size. Now days, I'm up to around 180M size ( a little less ) running Nodejs + express + socket.io for a web appliance type application. So now that I am familiar with Debian again, my workflow is rather fluid. Not many problems, and when they do arise, I am more able to deal with them quickly. Without, my own system fighting against me every step of the way . . . Anyway, everyone uses what they like best, and that has been my own personal experiences. You mileage may vary.
