As long as you use specific instructions to yum like "yum install
foo.1-3.386" and you have a clean and simple set of conf/repos files,
then yum will do a very specific thing. If you have multiple
repositories in your configuration and you just say "yum update" then
it might not behave exactly as you desire.
