==== Add the host to the createrepo channel ====
Channels are a way to control which builders process which tasks. By default
hosts are added to the ''default'' channel. At least some build hosts also needs to be added
to the ''createrepo'' channel so there will be someone to process repo creation tasks initiated by kojira.
