I would highly recommend you DON'T use "service network restart" if
you're using NM.  The two are not compatible in many areas.

I believe that's what's required if you do some manual reconfig of the
network behind NM's back.

I'm not sure they do.  I believe the idea is that NM would ONLY futz
with interfaces marked thus and leave the others alone.

With both classic and NM enabled, the normal startup sequence would
"service network start" at sequence 10, then "service NetworkManager 
start" at sequence 23  The way I read it, classic could play with all
the NICs and NM would only touch the ones marked "NM_CONTROLLED",
undoing what classic did to them.
