That's normal. It's a dbus-invoked service. You don't need to manually
enable it. It runs a command when it's invoked, and then terminates.
There isn't a daemon process associated with the service.

Not really. The log might tell you why it thinks an interface wasn't
successfully enabled.

Not generally. If you find the old network service works better for
your use case, it's available. I use it on a small number of hosts
where NM bugs interfere with normal operation, but I'm waiting for the
7.3 updates (where NM has been rebased to a newer version) to see if I
can stop doing that.
