This will get some more work, but I didn’t find much out there so this is a good starting point for someone

It appears straightforward enough, but feel free to ask any questions. You’ll need the rest of your operations platform pre-built, such as existing vmware hosts, pxe booting a debian install, etc.

I don’t think blogger is killing anything important. Some day I’ll setup an actual repository instead of using blogger for this crap. On the new server, next vacation. 🙂
