pi-gen: clear leftover BUILD_DIR at startup (robust to killed builds) 
A SIGTERM/kill (e.g. `systemctl stop`) skips the EXIT-trap cleanup, leaving
/var/tmp/wrolpi-build-pi-gen behind. The next build's `mv pi-gen-bookworm-arm64
wrolpi-build-pi-gen` would then nest into the stale dir and fail. Remove the
leftover (and intermediate zip/unzip dir) at startup, mirroring the debian
build, stripping immutable flags off blob files first.

Pi-Gen

This directory exists to facilitate the creation of WROLPI Raspberry Pi OS images.

See https://github.com/RPI-Distro/pi-gen

Generate 64bit Raspberry Pi WROLPi image

  1. Convert a map PBF file to your initial map DB dump:

    docker run --rm -v /home/user/district-of-columbia-230111.osm.pbf:/data/region.osm.pbf lrnselfreliance/osm-map-dumper > pi-gen/stage2/04-wrolpi/files/map-db-gis.dump

    The output is already compressed (PostgreSQL custom format with --compress 9).

    Verify the dump format is correct:

    file pi-gen/stage2/04-wrolpi/files/map-db-gis.dump
# Should show: "PostgreSQL custom database dump"

  2. Run the build (or, with a specific git branch)

    • Build release branch (default)

      sudo ./build.sh

    • Build specific branch

      sudo ./build.sh -b master

  3. The images are now in the pi-gen directory.
