Ferruh and Thinh,

Yes, that will also work and should trigger the rebuild to the tip of the
current git repo / branch.  Apologizes for forgetting that behavior is
built into the runner.

All,

That raises the question, for the planned work to allow triggering rebuilds
/ reruns through patchwork, what is the expected behavior, rerun exactly
what was run before, or move to the current pointer (assuming it's moved
on) and build/run on top of that?  What best aligns with everyone's
expectations, so we don't get confusion, etc.?

Cheers,
Lincoln
