SCPM profile switch, at init.3 & after network, based on IP?

Hi, All!

In a nutshell, I want SCPM to switch to a profile based upon what (IP|network/netmask) is assigned before my laptop reaches init.5 and xorg.conf starts up. I use NetworkManager to manage network; SCPM for xorg.conf, cups, mounts, and other things.

I think I need to create a /etc/init.3/S99local or some such via the skeleton template.

How do I do it?

Is this the most effective method of doing this and are there alternatives?

See my post here for more details and background if needed.

Many TIA!
