That's all great information. Thank you.

I do know about some issues regarding upgrading, and that's next on my roadmap to clean up.

Since there are some issues with older versions and 'unconfig', in the installer, I'm just going to check if there's a berrybrew installed, warn the user on what to do so they can proceed. I'm not going to make changes to the system; I'm going to let the user do that if necessary. Better safe than sorry.
