This is exactly what I want to find out. :)

The main goal is this: If I install a package XYZ can I rebuild it 
locally and get the exact same output, bit-by-bit identical.

The build environment being as close to upstream build environment is a 
prerequisite to achieve that goal.
It does not necessarily mean it has to be 100% identical though, some 
differences may be forgiving.
