Matthew Kassawara 677d910899 [install] Fix environment structure 
Address various structure and consistency issues with
environment content.

This patch only addresses the critical structure and
consistency problems that impact usability. A future
patch should address the larger, but less obvious problems
that mostly appeared during the RST conversion.
