-----------------------------------
[~vinodkv] or [~jlowe] do you have any further feedback on this patch or am I

> When processing environment variables for a container context the code
> assumes that the value should be appended to any pre-existing value in the
> environment. This may be desired behavior for handling path-like environment
> variables such as PATH, LD_LIBRARY_PATH, CLASSPATH, etc. but it is a
> non-intuitive and harmful way to handle any variable that does not have
> path-like semantics.
