* ``DIB_GRUB_TIMEOUT`` sets the ``grub`` menu timeout. It defaults to
5 seconds. Set this to 0 (no timeout) for fast boot times.
* ``DIB_GRUB_TIMEOUT_STYLE`` sets the visibility of the ``grub`` menu.
It defaults to ``hidden`` (or ``countdown`` as an alias). Set this to
``menu`` to display the menu and then wait for the timeout set by
``DIB_GRUB_TIMEOUT`` to expire before booting the default entry.
* ``DIB_BOOTLOADER_DEFAULT_CMDLINE`` sets parameters that are appended
to the ``GRUB_CMDLINE_LINUX_DEFAULT`` values in ``grub.cfg``
configuration. It defaults to ``nofb nomodeset gfxpayload=text``.

The ``bootloader`` element will explicitly set the timeout style to
``hidden`` to hide the menu. Set ``DIB_GRUB_TIMEOUT_STYLE`` to ``menu``
to display the menu and then wait for the timeout expire before booting
the default entry.
