I mean through a "normal" upgrade via the installer, booting from the
media (CD or DVD), I knew about getting a local yum repository with the
createrepo, I use it on intranet to update several installation with a
local mirror when updates for relases are available.
I did not think of extracting packages from CD, I rather use the CD, and
to be honest, even if I knew before, I still would have gone with the CD
direct option.
