the defs file. Re-arranged some of the existing snippets to make it
somewhat more cohesive, though it could still use a lot more work in
this area. Also, moved all of the remaining stuff about what to copy
from an old boss node (which was the original purpose of the document)
to the end, so that it's more geared toward people setting up their
own boss.

Still needs some documentation (and probably a script for auto-generating)
DNS config files.
