Hi,

If I try to follow the upgrade procedure you
recommended, I get the message:
 package yum-conf-41-4.SL is already installed
Does this mean my yum is set up to update to sl41?

I did yum update, it updated only 7 packages. However,
I should note here that a couple of days ago I had
updated my system from the SL repos using up2date,
which had installed 143 packages... does this mean
that I have a complete system from SL repos?

Thanks,
--Vaibhav
