But! There are only about 13 results for "embedded theologian". So my status as a special snowflake is preserved, however tenuously, for the moment :-)
For your embedded hacking pleasure : Tiny Core Linux
A 10MB basic distribution based on BusyBox, TinyX, Fltk, and Linux 2.6. Apparently from the same guys who brought us Damn Small Linux, which is a porky 50MB in comparison.
I've seen Linux systems (kernel + root file system) that fit in under 2MB... but of course, they didn't include a functioning UI and X Windows. Still, it's fun to see how usably Linux is even in very small systems.
