OK, so I'll send a patch to implement this soilution.

Thanks! :-)

Yes, then we can update to a newer version of the distro.

There was also a wild suggestion that we provide more Docker images,
for each of the mainstream distros.

Because sometimes, build issues only occur on some distros and not
others, e.g. arch-linux, which uses musl, sometimes break the build of
some host packages, and it is difficult to diagnose and fix...

I was also looking into providing additional Dockerfiles for additional
distros. I'll get this in the same series. Soon. Sooooon.... ;-)
