- firewall.nix: allow DNS (UDP/TCP 53) from all podman bridge networks
(10.89.0.0/16); NixOS only auto-adds a rule for podman0 but docker-compose
arion stacks land on podman1/2/3 where container DNS was silently blocked
- vnc-desktop/start.sh: rm stale /tmp/.X1-lock on container start so
container restarts don't leave Xvnc unable to bind display :1
- linux.nix: TasksMax=infinity on arion-vnc-desktop so the systemd cgroup
doesn't cap KDE Plasma's thread count below the container pids limit
- arion-riverside/arion-compose.nix: add ADMIN_PASS env var required by
the riverside entrypoint
