The other suggestions would work to remove an item from the run_list
but if I understand you correctly, your dns cookbook isn't on the
run_list directly, it's in a role. So that won't work. You can remove
the role, but that isn't what you want. You can edit the role to
remove the recipe, but then the next time you spin up a node it won't
be in the role. If the recipe is idempotent, why do you care if its
removed? Typically you'd want to leave it there so that it will
continue to revalidate the intended state on future chef runs.

If you really do need a one-time recipe, you'd need to put it on the
run_list directly (not in a role) but then I believe there's a way
that you can make a recipe remove itself from the run_list so it could
make itself one-time. Alternatively, there was talk about override run
list and one shot recipe features a while back. I think some of that
was implemented and maybe could help but I don't know the details.
