While lappy was gone I spent some time working to set up an embedded linux environment. I compiled up a kernel, built busybox, and installed bash on a little compact flash card.
It's pretty cool. The goal is to get an embedded erlang environment running on it.
It didn't take too long. Once I rememberd that you can only open /dev/console when /dev/console exists things really came together. It only took an evening to compile the kernel and get the other utilities in place.
It's hard to get much more basic than this when running linux.
This all reminds me of the days when I worked at Century Software. Embedded linux can be fun. I hope to have time to do more of it.
