Subject: [PATCH] setup.sh: make sure initialPath goes at end of HOST_PATH
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We want initialPath to have lowest precedence.

In addition, unset _PATH and _HOST_PATH as they shouldn’t be needed
after final PATH and HOST_PATH are set.
