Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+ If you say N here, the kernel will run on single and multiprocessor

+ the process as file descriptors supporting the read/write
+ syscalls, it's possible to isolate those applications in
