When I do a
yum check-update on a CentOS machine, I see that some updates are from the base repo, and some from the updates repo. Can anyone tell me what the difference between the two are? I have found the repositories guide but that is only about non-standard repositories - it has nothing about the default repositories.
My best guess would be that the base repository would get updated when CentOS goes from (say) 5.5 to 5.6, while in between any new packages would go into the updates repository. But I can't find anything on the internet about it - the search terms are too general to zero in on it.
