Unfortunately, this is not sufficiently reliable. Some idiot may
re-run it, and from some bitter experience, I don't trust the
system-config-network to behave well. NetworkManager is awkward to
rip out of RHEL 6. (Not modular enough: too many tools that don't
actually need it have RPM dependencies on it, so it winds up
re-installed anyway.)
The key to *keeping* it off in RHEL 6, and I assume in CentOS 6, is
the setting NM_CONTROLLED="no" in the
/etc/sysconfig/network-scripts/ifcfg-* files. This is a new setting in
RHEL 6, and I'm having difficulty finding documentation for it, but it
seems to work in keeping NetworkManager's greedy little paws off my
stable settings.
