Lon Hohberger 0cf0942068 Use architecture-specific grub2 RPMs on RHEL8 
RHEL8 ships a bunch of grub2-efi-X-modules in its main
repository, each of which provides grub2-efi-modules,
potentially causing nondeterminism when building images.

This changes the DIB elements to always use architecture-
specific RPMs when RHEL8 is selected.

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 vga=normal.
