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 the CMDLINE parameters that are appended to the grub.cfg configuration. It defaults to 'nofb nomodeset vga=normal'
