Can i programmatically tell if user input is required?

It might require reinventing the logic used by the ports system Makefiles. Or maybe there's a way to run make config-recursive but get dialog to immediately cancel any config screens that appear (redirect input from /dev/null?). Detect whether the output of that is not empty.

'make config-recursive' was already mentioned, but portupgrade has the -c and -C options, and running all the config screens before starting a build is automatic for portmaster.
