I am currently running Scientific Linux 4.0.
I have noticed that /etc/yum.conf installed by the yum-conf-40-4.SL
package contains the line "distroverpkg=redhat-release".
There is no package called "redhat-release" installed on my system.
Shouldn't that be "distroverpkg=sl-release" ?
The yum.conf man page says:
distroverpkg
The package used by yum to determine the "version" of the
distribution.
This might be an issue if you try to do a "yum upgrade" instead of "yum
update".
