Since GNUnet is supposed to be available to unprivileged users via
‘gnunet-arm’, perhaps you could clarify a bit what this does and what
the tradeoffs are?

Prefer (file-append shadow "/sbin/nologin").

The .local, .share, and .config sub-directories here look fishy.  I’d
suggest reporting that as a bug upstream.  :-)

The rest LGTM!
