#
# Orchestrates building all seven Slackware .txz packages this plugin ships
# (podman, conmon, crun, netavark, aardvark-dns, passt, fuse-overlayfs), by
# running each package's <name>.SlackBuild in turn. See
# docs/ARCHITECTURE.md section 5.2 (Build-Strategie).
#
# This script itself does not containerize anything — it assumes it is
# already running inside a Slackware-compatible build environment (see
# .github/workflows/build-packages.yml, which runs it inside a pinned
# Slackware Docker image). Running it on a non-Slackware host will likely
# still compile successfully for most components but the resulting .txz
# should not be trusted for an actual Unraid install — see the container
# image note in the CI workflow.
#
# Usage:
#   scripts/build-packages.sh                 # build all packages
#   scripts/build-packages.sh podman conmon    # build only the named ones
#
# Output: $REPO_ROOT/dist/<name>-<version>-<arch>-<build><tag>.txz
#         plus a .sha256 and .md5 sidecar file per package (see
#         scripts/lib/slackbuild-common.sh, sb_make_package).
# Nothing under dist/ is committed to git — see .gitignore.

# dependency/tag mistake, so faster packages surface problems first during
# local iteration. unraid-podman is genuinely last since it packages this
# repo's own files and has no compile step at all.
