Ask the developers. Patches welcome.

Yes that's a risk so make sure to have the steps figured out before 
doing anything. Having direct access to a (serial) console comes in 
handy if things fall apart.

I'm not aware of an RDO guide on this subject. The steps on each node are:
- create appropriate ifcfg-XXX files
- stop NetworkManager
- disable NetworkManager
- enable network
- start network

You probably want to do the last 4 steps in one long command or else you 
will loose connectivity after stopping NetworkManager if you are not 
using a console.
