That's great, thanks!

I don't know if this is really necessary. After all, it just a static 
conf and initscripts can just check if an interface is already up?

Anyway, the syntax to use on the commandline is ip=... See 
http://apps.sourceforge.net/trac/dracut/wiki/commandline for more 
information.

As for a file format, why not ask the NetworkManager people what they'd 
like to have?

Hope that helps
