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!

b. Caldera OpenLinux 2.2
|
|
Use LISA to load the cmpci module.
|
|
|
|
c. RedHat 6.0 and S.u.S.E. 6.1
