dual boot test

The 1st OS will be the os that gets run, it's the "master".. However
if I detect that it's hacked, I want to be able to reinstall the OS.

Noramlly, you'd do that with a cd, and do it manually, but if you
don't have access to the box, then what?

My approach is to have a 2nd minimal system/OS that has the only
function to invoke a complete/fresh netinstall to restore/refresh the
OS on the 1st system.

This allows the 1st OS/system to be completely restored, wiping out
any remnants of the hacked process.

At the same time, the master/2nd OS will periodically update/restore
the minimal/1st OS by the 2nd OS/system. This process allows the
system to be able to be refreshed as required, with a clean OS..

If you have a better approach, I'm open for discussion.
