A GUI and a registry; and I agree with that assessment.

There is a CLI to manage (but not edit) connections with NetworkManager 
in C6.  EL7 is supposed to improve the CLI functionality of NM, but that 
remains to be seen (meaning I've not taken the time to try it, as it's 
not really high on my list of priorities).  The command is nmcli, and it 
takes a bit of reading to see what it is doing.  It also takes a bit of 
thought, since NM is connection, rather than interface, oriented.

Earlier versions do seem to be more opaque than they probably should be, 
which is probably one of the primary reasons NM is in the Desktop group, 
and you get the Traditional networking if you don't install that group, 
or NM on its own, at least in C6.

I understand your pain, and your needs.  Many days my production 
environment feels that way.
