it's not at all obvious to me how to do this within a FAI hook/postinst
without breaking the rest of the current softupdate run.

How about this: if STDOUT is a terminal, prompt the user whether to rm
-rf, otherwise abort with an error? Of course we should also check for
the case of just an empty directory, which can be safely deleted.
