This is the new Rhino Linux (RL) ISO builder (replaces the formerly known RRR-builder) which creates images from scratch and gives us (even) more control over the final image. To set up the builder:

• sudo apt-get update && sudo apt-get install --reinstall debootstrap -y
• sudo mv /usr/share/debootstrap/functions functions
• sudo patch -i 0002-remove-WRONGSUITE-error.patch
• sudo mv functions /usr/share/debootstrap/functions
• sudo ln -sfn /usr/share/debootstrap/scripts/gutsy /usr/share/debootstrap/scripts/lunar
• sudo dpkg -i debs/live-build_*_all.deb
• sudo cp binary_grub-efi /usr/lib/live/build/binary_grub-efi
• sudo chmod -R +x build.sh etc/auto/config etc/terraform.conf etc/

Then, to build:

sudo ./build.sh etc/terraform.conf

The resulting ISO, if successful, will be located in builds/$ARCH. The builder should automatically detect whether to build on ARM64 or AMD64, depending on the machine you run it on. 32-bit images are unsupported.

This build system creates the images using lb/live-build with debootstrap to create images with configuration in etc folder.
