Scenario: NOC with 30 machines.
We have our own yum mirror and debian mrirros. All config for apt-get and yum get files from one our machines.
- minor bandiwth and any tiem tiemout for overloaded mirrors .
- Update from original sites and checksum verification.
A great idea, Cpanel team work on this way. Rsync or any system for Hosting providers has a own mirror of cpnale updates.
A nice day.
