Channel subscription from command-line support added to the Unbreakable Linux Network(ULN)

Until recently, to add channels to a server or to register a server as a yum-repository server, one had to log into ULN and manually do this. First a server had to be tagged as a yum server and then any channels that would be included, would have to be added to this server. While this is an easy task, it does involve logging into the website, and manually following a few steps and it could not be automated.

We provided an updated rhn-setup RPM that now adds a new tool called uln-channel which allows users with ULN access to enable a server as a yum server and also add/remove/list channels for this server. This will allow for easy automation.

The latest version of the rhn-setup rpm is rhn-setup-1.0.0.1-16.0.9.el6.noarch. The uln-channel rpm is currently only supported with Oracle Linux version 6.
