So because the devkit is debian, and the prod image is apline we have a split in what ssh options are allowed ;(. I know originally the devkit was also alpine, but it got switched before opensourcing it due to bash vs sh-isms.

What would the feeling be to switch the devkit back to alpine and just make sure to install bash and set it as the default shell? This will make sure we are using the same base platform that the wrapper is, just with go and all the extra tools installed.
