The reverse proxy runs on a different host than the game server, so it cannot
alias the share directly — serving the pack needs an HTTP server on the game
server itself.
packwiz-http.py is a threaded static server over an allowlist: mods/, packs/,
and setup-*.html. Everything else 404s, since the same directory holds
server.properties, ops.json, whitelist.json, logs and the world. Threading
matters because installing a pack is one request per mod and a single-threaded
server serialises a whole lobby behind one download. pack.toml and index.toml
are sent no-cache so a proxy cannot serve a stale pack.
Installed as packwiz-http.service on port 18080 by default, configurable with
-H/-B, skippable with --no-http, and read-only via ReadOnlyPaths.
packwiz-setup.sh gains -S/--scheme, for when the pack is built against a mirror
reachable only over plain HTTP but clients must be handed the public HTTPS URL.

Deriving the site URL by reducing the mirror URL to its origin discarded any
base path, so a mirror at https://host/abdelpakDelta/mods produced a pack URL
of https://host/packs/<slug> — a location nothing serves. Strip the last path
segment instead, which gives the right answer with or without a base path.
The server address derivation also only stripped scheme and port, so a site URL
carrying a path leaked it into the address shown to players. Strip the path too.

Re-running previously died at step 2, because packwiz-setup.sh refused to
overwrite an existing pack.toml — so a run that failed partway, or any later
change to port or heap, could not be applied by simply running it again.
deploy.sh now snapshots the dataset, stops the server if it was running,
redeploys, and restarts it only if it had been up. packwiz-setup.sh gains
--force, which moves an existing pack to <pack>.bak.<timestamp> rather than
deleting it, since the directory may hold hand-edited .pw.toml files or git
history. deploy.sh passes --force unless --keep-pack is given.
World data and the server's mods directory are untouched throughout.
Also replaces the hardcoded sed line ranges in every usage() with an awk that
prints the leading comment block, so help text stops drifting out of sync when
the header changes.

Threads a port through all three scripts. mc-service-setup.sh writes
server-port into server.properties (updating in place so a generated file keeps
its other settings) and opens the port in firewalld. packwiz-setup.sh renders it
into the player guides.
The guides print a bare hostname on 25565 and host:port otherwise — Minecraft
assumes the default, and a needless ":25565" in the address reliably confuses
players.

13G left roughly 1G for the OS once the ZFS ARC cap is accounted for. 10G plus
a 2G ARC leaves comfortable headroom on a 16G host.

mktemp -d creates a 0700 directory owned by root, so handing the downloaded
installer jar to the minecraft user via runuser failed with "Unable to access
jarfile". Relax the temp path to 0755/0644 — the installer is a public
download and holds nothing sensitive.
Also set HOME explicitly for the runuser invocation, since it otherwise
inherits root's and the installer writes a cache alongside it.

deploy.sh previously required -N and failed outright without it. It now passes
-N latest by default, and mc-service-setup.sh resolves the newest stable build
in the series matching the Minecraft version from the NeoForged maven
(1.21.1 -> 21.1.x, 1.21 -> 21.0.x), excluding betas. Pin a version with -N to
opt out.
Heap defaults raised to 13G for both Xms and Xmx. README documents capping the
ZFS ARC alongside it, since ARC defaults to half of RAM and would otherwise
contend with a heap this size on the same box.

Deploys a self-hosted NeoForge server whose modpack clients pull automatically
on launch, with mods served from an HTTP mirror of the server's own mods dir
rather than Modrinth or CurseForge.
- mc-service-setup.sh: minecraft user, NeoForge install, systemd service paired
with a console FIFO socket so stops are graceful and the world saves
- packwiz-setup.sh: packwiz install, pack init, mod index built from the
mirror, and per-OS player setup guides generated with real URLs baked in
- mc-refresh-restart.sh: re-sync after mod changes, ZFS snapshot, restart
- deploy.sh: runs the above in order
- build.sh: release zip, refusing to package scripts that don't parse
Every entry point refuses to run when /minecraft is not a mountpoint, so an
unmounted dataset cannot silently fill the root filesystem.
