Commit https://github.com/dry-dock/u14/commit/3d1c2515493d1491ff732773fde28ab0b7e6e4e4 introduced an unexpected behavior of $PATH.
$PATH
Normally $PATH can be expanded this way:
$ docker run --rm -it ubuntu:16.04 $ root@aa190d3433ca:/# PATH="$PATH:/test" bash -c 'echo $PATH' /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/test
The change above introduced an unexpected behavior (notice missing :/test at the end):
:/test
$ docker run --rm -it drydock/u16 $ root@d248ceeef5de:/# PATH="$PATH:/test" bash -c 'echo $PATH' /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/lib/jvm/java-11-oraclejdk-amd64/bin
The consequence is that basically if anything adds something to $PATH the change is not propagated to any script calls, causing erroneous and very unexpected behavior. We noticed it when bats stopped working with the latest version of your images.
