#!/usr/bin/env bash
# install_pkg.sh — Install a built CA .txz onto Unraid from the Mac.
#
# scp's the package into /tmp on the Unraid box and runs `installpkg`
# over the same ssh transport. No SMB share involvement, no AppleDouble
# / chflags weirdness, no leftover files in /mnt/user/GitHub. The remote
# /tmp copy is removed once installpkg returns.
#
# Usage:
#   ./install_pkg.sh                       # newest .txz in ./archive/
#   ./install_pkg.sh path/to/file.txz      # explicit package
#
# SSH target resolution (no hostname ever lives in tracked source):
#   1. UNRAID_HOST env var, if set
#   2. ./.unraid-host file at the repo root (single line "user@host")
#   Neither -> the script exits with a setup hint.
# The .unraid-host file is gitignored so the box you push to (often a
# Tailscale name) never leaks into the repo or a fresh clone.
