1. Download Debian 12 DVD at least DVD1 put at outside of repository
2. Follow the requirement at CMake

Build

Follow these steps paste-in-command:

Download Debootstrap

1. bash setup.sh --download-debian12
2. cp build/debian-12.tar.gz ..

Setting Up

1. bash setup.sh --clean
2. bash setup.sh --setup
3. bash setup.sh --build-raw
4. cp ../debian-12.tar.gz build/
5. bash setup.sh --set-base-os
6. bash setup.sh --mount-dvd
7. bash setup.sh --set-kernel
8. bash setup.sh --set-uefi-boot
9. bash setup.sh --create-vmdk
10. bash setup.sh --create-vboxvm (run vbox, stop vm after boot fail)
11. rm -rf build/log/set-*
12. bash setup.sh --unmount-dvd

Removing

Follow these steps paste-in-command:

1. bash setup.sh --remove-vboxvm
2. bash setup.sh --unmount-dvd
3. bash setup.sh --unmount-linux (repeat until no-output)
4. bash setup.sh --unloop
5. bash setup.sh --clean

Checking up result: losetup -a | grep $USER mount | grep $USER

losetup --find --show

losetup -d /dev/loop31

udisksctl loop-setup -f build/${VM_NAME}.raw | head -c -2 | cut -f 5 -d " " &> build/DEV_LOOP

cat build/DEV_LOOP | xargs -I {} udisksctl mount --block-device {}p3 --filesystem-type=auto --no-user-interaction | cut -f 4 -d " " &> build/ROOT_PART

sudo chroot /media/$USER/root bash -c 'df -h'
