Fine with me, I wasn't sure on the best procedure for things like
this. It's not something you plug / unplug at run time, you'd
tend to just always have this, or not. Is it best to just have
user space distributions handle selecting the overlay then? and
they maintain the overlay file?

I'd considered overlays something for _per user_ customization,
but I'm perfectly happy if it it's intended to be used for per
product customization too if that's the right method.

Sincerely,
Karl Palsson
