Hi.
Redhat 7.2 ISOs (and files) are available on
db.ilu-bom.org.in
The URL is
http://db.ilug-bom.org.in/redhat/
You can download the ISO, burn and use, or get individual packages you
wish to upgrade and install them.
There might be some changes in the directory structure over time, but that
shouldn't really be a problem. A nice web-interface is also being worked
upon.
cheers!
