> Looks ok. I would commit update separately form dropping patches. Can you also change to `version=5.0.018` and derive rest of variables from it?

Initially, I reluctant to derive it since it would involve bashism somewhere, and we may run with `/bin/sh` point to something else on bootstrap.

Now, I've re-read the code, I think we'll be fine since we asked for `/bin/bash` directly.

I'll change in a minute.
