      # we should put "nix:/nix:ro but it is not supported by
      # drone-runner-docker because the dependency envconfig does
      # not support having two colons (:) in the same stanza.
      # Without the RO flag (or using docker userns), build isolation
      # is broken.

      # https://github.com/kelseyhightower/envconfig/pull/153
      #
      # A workaround for isolation is to configure docker with a userns,
      # so even if the folder is writable to root, it is not to any non
      # privileged docker daemon ran by drone!
