Recently I was surprised to see that a Puppet/Foreman installed server
with operating system SL6.4 would immediately switch to SL6.5.
I do not know if some people got bitten by the same thing but it took
me some time to realize that this was the consequence because of
yum-conf-sl6x being installed by default on SL6.4  and the
availability of SL6.5.
As I prefer to manage myself the version of SL used on production
servers, I looked for a way to prevent this and I chose to hack the
Kickstart file :
%packages --excludedocs --nobase
I do not know if there is a better way. Am I the only one to experience
this issue ?
