I think we should work on making this possible. A program might set all
sorts of parameters before (dynamically) requiring a Planet path. Those
settings should apply while loading the package's modules after it's
installed, but they shouldn't affect installation of the package.
Installation should always act the same --- as if a completely new
OS-level process was started to install the package.

I don't immediately know how to make that work (without actually
starting a process), but that seems like the right path.
