==========
bootloader
==========
Installs ``grub[2]`` on boot partition on the system.
Arguments
=========
* ``DIB_GRUB_TIMEOUT`` sets the ``grub`` menu timeout. It defaults to
1 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``.
* ``DIB_BOOTLOADER_USE_SERIAL_CONSOLE`` allows usage of a serial console
to be disabled in the resulting image by setting to a value of ``False``.
* ``DIB_BOOTLOADER_SERIAL_CONSOLE`` sets the serial device to be
used as a console. It defaults to ``hvc0`` for PowerPC,
``ttyAMA0,115200`` for ARM64, otherwise ``ttyS0,115200``.
* ``DIB_BOOTLOADER_VIRTUAL_TERMINAL`` sets the virtual terminal be
used as a console. It defaults to ``tty0``. When explicitly set
to an empty string then no virtual terminal console kernel argument
is added.
* ``DIB_NO_TIMER_CHECK`` allows the default kernel argument,
``no_timer_check`` to be removed from the kernel command line
when the value is set to ``False``.
* ``DIB_SKIP_GRUB_PACKAGE_INSTALL`` when set to ``True`` will not install any
grub packages, and will assume all necessary packages are already installed.
