========== 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. Arguments ========= * ``DIB_GRUB_TIMEOUT`` sets the ``grub`` menu timeout. It defaults to 5 seconds. Set this to 0 (no timeout) for fast boot times. * ``DIB_BOOTLOADER_DEFAULT_CMDLINE`` sets the CMDLINE parameters that are appended to the grub.cfg configuration. It defaults to 'nofb nomodeset vga=normal'
