I think there is another angle here, which is that this command's output
has the possibility of triggering an "oh ----" (fill in your preferred
colorful metaphor here) moment, followed up by a panicked Ctrl-C. That
reaction has the possibility of causing its own problems (i.e. not sure if
mmafmctl touches CCR, but aborting it midway could leave CCR inconsistent).
I'm with Jonathan here: the command should fail with an informative
message, and the admin can correct the problem (just cd somewhere else).
