How Small Can Linux Be?
Taco Cowboy asks: "In the embedded market, the smaller the better, and I've scoured the Net in my own personal search for the tiniest Linux kernel available for the embedded market, and so far, the best I can come up with is one that claims to have a 143K footprint! (Sorry, I have NOT tested that product, so I won't know if the claim is valid or not). Is there anyone out there who knows anything smaller?"
If you remove all the functionality from a linux kernel, is it still a linux kernel?
I'd say that the question you should be asking is "what is the smallest kernel which will do what I want?"
