bootloader
==========
Installs ``grub[2]`` on boot partition on the system. In case GRUB2 is
not available in the system, a fallback to Extlinux will happen. It's
also possible to enforce the use of Extlinux by exporting a
``DIB_EXTLINUX`` variable to the environment.
Installs ``grub[2]`` on boot partition on the system.
