So there's no way e-v-e-r "it just works", especially docker, you have the feeling because you kind of used to it and might never seen a fast, responsive and reliable system (on the long run). I had the same kind of setup on several jobs and nope, nope-nope, noooope.

But hey, kudos if you succeed to do your job in such condition without hurting yourself, good sign of resilience. :)
