NM will look in /etc/sysconfig/network-scripts/ for ifcfg files that are
there, and use those if found.  However, the files must not have
NM_CONTROLLED=no in them, because that tells NM not to manage the
interface.  At least at one point, system-config-network would add
NM_CONTROLLED=no by default when it edited a configuration that didn't
have that tag in it already, which caught a few people by surprise.
