# PIDFile is worse than useless here: it embeds the container ID, so it goes
# stale every time a deploy recreates the container.

# own child, so the exit is seen and Restart=always fires.

# output on podman's stdout, which systemd would capture straight back into the

# Priority 4/5: query flood limiting.
#
# The original thresholds were 1/hour burst 2 per source IP, on the theory that
# only scanners send 53-byte query packets and that real players would first be
# marked verified by the priority-2 rule when they sent something else. That
# premise is inverted: a client's *first* contact is a 53-byte query, so nobody
# can be verified before they query, and nobody can query more than twice an
# hour without being dropped. The counters were unambiguous -- 5 packets ever
# matched the verified-accept rule against 30,563 drops -- and fail2ban then
# banned the dropped players for a week each, several an hour, all residential
# IPs. The server was unreachable for everyone.
#
# Remove the old rules so hosts carrying them converge, then re-add the same
# shape at a threshold no real client reaches. Opening the server browser sends
# a handful of queries; a flood sends thousands.
