Ghosting The Machine

This is a short but potentially extremely handy guide to ghosting
one Linux box to another (or simply making a full backup of a
desktop/server). You might have a small office where you customise one desktop
just how you like it and need to roll this out to N other PC’s or
simply want a backup of a server or desktop to another machine or even
to an image file. The main tool here is netcat which is extremely powerful and has a
multitude of other great uses that won’t be covered here.
