Creating your own disk images
Best should be to add as many as possible changes into setup.sh
and
keep the disk images generic.
You should have Debian 10 or newer installed to run these scripts yourself.
sudo apt-get install vmdb2 dosfstools qemu qemu-user-static make #zip
git clone https://github.com/laroche/arm-devel-infrastructure
cd arm-devel-infrastructure/vmdb2-debian
edit debian-amd64.yaml
make
You can also just create individual images like:
make debian-amd64.img
