This is # necessary because transposefs doesn't yet rerun grub2-install on BIOS, # so GRUB still expects /boot to be a partition on the first disk. # # There are two consequences: # 1. On BIOS and UEFI, the search command might pick an individual RAID # component, but we want it to use the full RAID in case there are bad # sectors etc. The undocumented --hint option is supposed to support # this sort of override, but it doesn't seem to work, so we set $boot # directly. # 2. On BIOS, the "normal" module has already been loaded from an # individual RAID component, and $prefix still points there. We want # future module loads to come from the RAID, so we reset $prefix. # (On UEFI, the stub grub.cfg has already set $prefix properly.) set boot=md/md-boot set prefix=($boot)/grub2 else if [ -f ${config_directory}/bootuuid.cfg ]; then source ${config_directory}/bootuuid.cfg fi if [ -n "${BOOT_UUID}" ]; then search --fs-uuid "${BOOT_UUID}" --set boot --no-floppy else search --label boot --set boot --no-floppy fi fi set root=$boot if [ -f ${config_directory}/grubenv ]; then load_env -f ${config_directory}/grubenv elif [ -s $prefix/grubenv ]; then load_env fi if [ -f $prefix/console.cfg ]; then # Source in any GRUB console settings if provided by the user/platform source $prefix/console.cfg fi if [ x"${feature_menuentry_id}" = xy ]; then menuentry_id_option="--id" else menuentry_id_option="" fi function load_video { if [ x$feature_all_video_module = xy ]; then insmod all_video else insmod efi_gop insmod efi_uga insmod ieee1275_fb insmod vbe insmod vga insmod video_bochs insmod video_cirrus fi } # Other package code will be injected from here if [ x$feature_timeout_style = xy ] ; then set timeout_style=menu set timeout=1 # Fallback normal timeout code in case the timeout_style feature is # unavailable. else set timeout=1 fi # Import user defined configuration # tracker: https://github.com/coreos/fedora-coreos-tracker/issues/805 if [ -f $prefix/user.cfg ]; then source $prefix/user.cfg fi blscfg
