Thanks for looking into this! Unfortunately, it's not that easy to generate proper version bumps for most of the stuff in the Makefiles. I'd like to start with something really simple first, and then add more and more stuff to it. How about starting with just Alpine (as I think this is the only one that can be done by solely incrementing stuff in the Makefile), so that we have the skeleton and a simple example, and then add other stuff to it in individual PRs? I imagine that we need to restructure things a bit on a case by case basis for automatic version bumps to be working reliably.

Thanks @twz123, I'll update the PR to focus on Renovate on-boarding and Alpine only. Once that's in place, we can add other dependencies gradually in separate PRs. Appreciate the guidance!
