I know that you could spend a year or so digging into what files need to be removed, but I can't find them all so in the interest of time, I just start over.

Stuart that does not answer the question. IE fresh install mythtv-setup - ooops

I've got a new machine I want to play with.
I don't want that machine messing up my master db.
I don't want that frontend talking to or displaying recordings from the 'real' master backend
I don't want that backend to be a slave.

Great Myth: I do not have any fire wall in my network. The only port forward is ssh. Bad Guys can reach my modem then do nothing. It violates RFC to route private IPs.
So every router between bad guys and me needs to be broken AND my modem need to be broken for Bad Guys to get to me. So a flaw allows them to get to me, why is a fire wall going to help.
[firewalls do stop infected windows machines from calling OUT]

The only solution that works for me is to firewall the play machine (and you can do wonderous stuff eg a play frontend machine and a play backend. With ssh tunnels you can create magic,

As an alternative to Stuarts MYTHCONFDIR suggestion I use a .mythtv_a .mythtv_b and an alias (a mv .mythtv_a .mythtv) to switch a front end (same version) from real to play.

I've not tried, and mac with their bundle system make it trivally easy, to run 2 frontends say a 31 and a 32,

Building mythtv with different PREFIX would work together with the alias solution
