  The analogy here isn't convincing, possibly because the pkg(1)
  invocations above are a small subset of those available.  pkg
  uninstall of an unknown package gives a non-zero exit status; pkg
  install of an unknown package gives a non-zero exit status.  At the
  completion of the pkg install invocation in both the cases above, the
  requested package is actually installed.
