Timeline of a Master

The timeline

When a new version of the OS is ready (Redhat 6, ubuntu X.4/X.10,...) we must choose between installing a news computer, upgrade the system, or installing a new version of the OS but keeping the data

Upgrading the master

If we consider Debian or Redhat, its easy, we have to update the kickstart config or debconf setup.

Updating the master

It's just about updating the mirror or create additional mirror of our distrib.
