The TUV's technical notes for 6.0 say:
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Technical_Notes/networking.html
5. Networking
NetworkManager
NetworkManager is enabled by default if it is installed. However,
NetworkManager is only installed by default in the client use cases.
NetworkManager is available to be installed for the server use cases,
but is not included in the default installation.
And that doesn't seem to be mentioned in the 6.1 notes, so I assume it is
the same. Does sl6 include it by default in all standard installs?
