This provides bootable disk images for x86 platforms via ! RUN_OPT="--target disk" The resulting disk image contains one ext2 partition with binaries from the GRUB2 boot loader and the run scenario. The default disk size fits all binaries, but is configurable via ! --disk-size <size in MiB> in RUN_OPT. The feature depends on an grub2-head.img, which is part of the commit, but may also be generated by executing tool/create_grub2. The script generates a disk image prepared for one partition, which contains files for GRUB2. All image preparation steps that need superuser privileges are conducted by this script. The final step of writing the entire image to a disk must be executed later by sudo dd if=<image file> of=<device> bs=8M conv=fsync Fixes #1203.
