Steve Baker f7ba7ba1de Use the same bootloader pkg-map for all redhat family The only difference between the rhel and redhat entries is rhel has the extra grub-efi-x86_64 mapping. All redhat family releases would benefit from having this too, so this change removes the whole rhel entry and adds grub-efi-x86_64 to the redhat family. The assumption is that anything which applies to rhel also applies to centos-stream, and in this case doesn't harm centos or fedora either.

==========
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 parameters that are appended
  to the ``GRUB_CMDLINE_LINUX_DEFAULT`` values in ``grub.cfg``
  configuration. It defaults to ``nofb nomodeset gfxpayload=text``.

* ``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``.
