At some point a few years ago I explored a private testing pipeline that built VM with different combination of options. It worked, but there were so many issues that cropped up continuously that I scratched that off as the lost cause. I gave up even on building Minimal. Fixing the particular build configurations every once in a while -- like this PR -- seems to be a pragmatic compromise.
