I've merged this in so we can continue from there.

I see you've added a cobbler settings attribute to just generate/clobber the TFTP configuration file (from a template) which seems sane, though I wanted to know if you could explain a bit more about why this was done and what options would be used? > 3) After doing an import, you must cabextract all inf/cab files in the i386 > directory to someplace binlserver can read them, and then run infparser.py > on them.

Ultimately we just need to turn TFTP on, right?

You could likely hash off of that or follow that example to create more persist windows-specific IDs.

Basically what you have above but with examples and command lines, etc?
