Issue

• Looking for a command line way to create a child channel following the instructions in https://access.redhat.com/site/solutions/308983
• This doc describes the steps of creating a channel via UI, but looking for a 'space-walk' command to create one from command line. I can use the 'space-walk'command to sync the custom channel once its crated.
• Here is the message I get If I run the spacewalk-repo-sync command(below) before explicitly creating the channel.

1# spacewalk-repo-sync -c securityfirst -u http://yum.example.com/repos/rhel6/
Channel does not exist or is not custom.
