Merged requested to merge work/dzahn/build-golang into main
This package requires at least golang 1.16 to build.
In buster and bullseye there is only 1.15 and with that version builds fail with "package io/fs is not in GOROOT".
With 1.16 this issue is gone.
The package could be built with DIST=bullseye-backports which pulled in 1.17.
This is to prevent this issue the next time we build.
