There are a few packages I always install directly from source, to avoid lagging. Golang is one of them.

If you're using Debian, or some similar system, chances are your package manager will never deploy something beneath /opt. So in my case I configure golang to install in /opt/golang/

On this particular host I have only three packages here:

      $ ls /opt/
      arduino-1.8.0
      calibre
      go-1.8
