Dear Dag.
People may blame us for deviating from RHEL, which is what we will keep on doing if we leave the RHN libraries/client out.
Although I don't think I will be changing your mind, Marcus, because for your use-case there is no benefit.
And I personally see no benifits in including them and loosing flexibility without any real benefits (besides for mrepo users).
So let's end this thread (before we reiterate for the 7th time) with words from Miroslav Suchÿ, one of the Red Hat Spacewalk developers who stays out of this thread, likely intimidated by it :-)
Wasn't it Miroslav who also wanted to include these in EPEL, making it completly useless for managed RHEL systems? But anyhow, I have said what needs to be said.
Best Regards Marcus
