+
+## Run
+
+```bash
+gcc -static -o init/init init/init.c
+
+dd if=/dev/zero of=disk.img bs=1M count=512 status=none
+echo -e "n\np\n1\n2048\n\nw" | fdisk disk.img > /dev/null
+
+dd if=disk.img of=part.img bs=512 skip=2048 status=none
+
+mkfs.ext4 part.img
+debugfs -w -R "mkdir /boot" part.img
+debugfs -w -R "mkdir /boot/grub" part.img
+
+debugfs -w -R "write init/init /init" part.img
+debugfs -w -R "write linux/arch/x86/boot/bzImage /boot/bzImage" part.img
+debugfs -w -R "write grub/grub.cfg /boot/grub/grub.cfg" part.img
