Make bootable linux disk image abusing docker

docker-to-linux - make bootable linux disk image abusing docker

There is no real goal behind this project. Just out of my curiosity what if:

• launch a base Linux container (debian, alpine, etc)
• pull in Linux kernel & init system (systemd, OpenRC, etc)
• dump container's filesystem to a disk image
• install bootloader (syslinux) to this image...

Then it should be probably possible to launch a real virtual machine with such an image!

Try it out:

make debian
qemu-system-x86_64 -drive file=linux.img,index=0,media=disk,format=raw
make clean

make alpine
qemu-system-x86_64 -drive file=linux.img,index=0,media=disk,format=raw
make clean

It works!
