That’s respectable! But yeah, the FHS is something that’s surprisingly hard to find in-depth information about if you don’t already know about it.
I think this page from systemd (or this page from the arch wiki, if you prefer formatting) has a decent description of not only the FHS, but also the more standard user/home structures.
Is that in relation to DHT? Never got quite into it, but if you’re using a tracker then I’d imagine the tracker would handle the peer2peer reverse NAT problem.
