pkg_build.sh

#!/usr/bin/env bash
# Mac-native version of pkg_build.sh.
#
# Builds a Slackware-compatible .txz package from the source/ tree using
# BSD tar's built-in xz support (no Slackware `makepkg` required, no
# Unraid roundtrip). The result drops into ./archive/ and is installable
# on Unraid via `installpkg` exactly like the original .txz format.
#
# Usage:
#   ./pkg_build.sh            -> archive/community.applications-YYYY.MM.DD-x86_64-1.txz
#   ./pkg_build.sh <suffix>   -> archive/community.applications-YYYY.MM.DD<suffix>-x86_64-1.txz
#
# Replaces the legacy Linux script (saved as pkg_build.sh.bak) which used
# Slackware's makepkg + `cp --parents` (GNU-only) and only ran on Unraid.

# calls (and `tar -p` xattr preservation) from leaking AppleDouble entries.
# installpkg on Unraid sees a vanilla `tar xJf` archive — same shape the
# Slackware makepkg produced.
#
# Force root:root ownership in the archive. macOS builds the staging dir as the
# invoking user (e.g. uid 501/staff); without this override those ids get baked
# into the tar and upgradepkg would chown the installed plugin files to that
# non-root owner on the server. The legacy makepkg got root:root for free by
# running as root on Unraid — we reproduce that here.
