Hello Sven,

Thank you for your comments on the state of yum-conf-sl6x.

yum-conf-sl6x-1-2.noarch.rpm does not have any conflicts set.

$ rpm -qpi --conflicts yum-conf-sl6x-1-2.noarch.rpm

So I'm not sure what you mean by 'conflicts with sl-release'.

As for the the inclusion of yum-conf-sl6x in the default install, this was 
discussed at HEPiX Beijing (Oct 2012) in the presentation Connie and I 
wrote.[1]  When I solicited comments at that conference, no one expressed concern.

The 'x' repo configs were added to the default install of 5.9 Alpha on Jan 
10th (though my initial announcement could have been clearer).  And they were 
added to the default install of 6.4 Beta on March 1st.  This behavior was 
present for the entire pre-release cycle of both 5.9 and 6.4.

Up until now no one expressed any concerns over this change, and I've received 
a few off list emails expressing gratitude for this new behavior.

If yum-conf-sl{5,6}x is not suitable for your systems the rpms have been 
designed to be simple to remove without any additional labor. While these are 
'by default' they are not mandated by any parts of the system.  That was a 
core requirement of this change in default behavior.

I hope this has been a helpful clarification of how yum-conf-sl6x was added to 
the comps.
