Alright. It's basically making use of the programs yumdownloader, rpm, and
createrepo.
What I do is I have a machine that has the same setup as the other machines
in the isolated network. This machine has Internet access, so what I go to
some directory where I want to download the RPM packages into with
yumdownloader. In this directory, I run the following.
$ yumdownloader --resolve $(rpm -qa --qf
"%{NAME}-%{VERSION}-%{RELEASE}.%{ARCH} ")
Note that there is suppose to be a space after %{ARCH} in the formatting
string above. This takes a while, but eventually, all the packages get
downloaded. Once finished, I use createrepo to create a basic repository,
burn the new repo onto disc (the repo is about 1GB so I burn it to a DVD),
and then transfer the repo into a share directory in the isolated network.
Each machine has a .repo file under /etc/yum.repos.d/ which points to this
share, so to update each machine, it's simply a matter of running 'yum
update'.
