[bitbake-devel] [RFC PATCH 1/1] lib/bb: preserve a copy of the initial environment variables

[Joshua Lock]

We are gradually introducing code which wants to be able to modify the
initial environment of BitBake. The os.environ map is created on first
import of the os module so create a copy early on and store it for future
use.
