Steve Baker 5caeba0c68 Ensure redhat efi packages are reinstalled during finalise 
The rhel-8.4 qcow2 base image already has the grub2-efi-x64 package
installed on its single partition which has files installed to
/boot/efi..., however a partitioned image will have an empty /boot/efi
partition when running 50-bootloader. This means dnf will not install
grub2-efi-x64 when requested and /boot/efi will remain empty.

This commit makes the following changes:
- Refactors redhat bootloader pkg-map for the following:
  - Make x86_64/amd64, arm64/aarch64 adjancent so they don't diverge
  - Map grub-efi to packages installed to /usr
  - Map grub-efi-{arch} to packages installed to /boot/efi
- Removes packages grub-efi-{arch} before installing grub-efi and
  grub-efi-{arch}

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.
