Hosts which are managed by satellite may wish to be "locked" so that no changes are accidently made. This lock should ensure that:

1) No new content is consumed by the host
2) No configuration changes are made to the host
3) No remote execution commands are sent to the host

This was a feature of satellite 5 which can be read about at https://access.redhat.com/documentation/en-US/Red_Hat_Network/5.0.0/html/Reference_Guide/s3-sm-system-details.html.

There are some old bugs aroudn locking which should be included when implementing this RFE:
