Accessing more than one channel

Hello all,

I have a current install on a Redhat 7.3 machine, and I'm testing from a
Redhat 8.0 client.

Here is my valid_channels entry in my /etc/current/current.conf file:

valid_channels = redhat-8.0-i386 8.0-updates-i386

I have run cadmin -v create for each one of these entries, and get no
errors.  In fact, separately I can see each of these channels from my
client.

The problem I'm having is that I never see the channels together, only
the first channel is shown on the client.  For example, with the 
valid_channels line above, I will only see redhat-8.0-i386 channel when
I run up2date from the client.  If I reorder the valid_channels line so
that 8.0-updates-i386 is first, then I will only see the 
8.0-updates-i386 channel and not the redhat-8.0-i386 channel.

Both the redhat-8.0-i386 and 8.0-updates-i386 channels  work on 
their own, but I can't figure out why it won't list all valid_channels.

Any ideas?

Thanks!
