We should probably collect profiles of ~ (a personal home directory) and /
(the cross-user filesystem root) separately. Operating system files tend to
show up only in the latter, whereas things I've created or downloaded show up
in both. Each will have a different set of convergence statistics.

Zooko, is there an argument to specify the root directory that gets used?

A note for potential dupfilefind-installers: if you install with
--single-version-externally-managed (to use GNU stow), you'll forego the
setuptools dependency management, and then you'll need to manually install
the 'argparse' package as well:
