I think nowadays one would prefer --keep-going, which automatically resumes on
failure (and recomputes the dependency tree!), and prints a list of failed
packages when it's finished. However its output is more verbose than just "ok"
and "failed" (it'll print the build.log if it's only one package, IIRC).
