Hi Trevor:

I've been looking at some other issues with respect to profiles.
Haven't gotten very far.  But as near as I understand it, it's
not done with shell scripts but rather with Python "scripts".
Unfortunately, I don't really read Python very well.  I think
that it is the "Python program"

/usr/share/system-config-network/netconf.py

along with other "programs" in that directory.  Note that
"Python" is a form of script (Python people don't shoot me!)
in the sense that these "programs" are ASCII text files
"executed" by the interpreter "/usr/bin/python".
