This commit fixes this bug. It may have fixed some potential -bugs as well. - -There are 4 partitions in a LifseaOS disk image: -- The 1st partition is for BIOS bootloader -- The 2nd partition is for UEFI booting, which contains grub binary - compiled from this source code, grubaa64.efi -- The 3rd partition contains grub.cfg files and - loader/entries/ostree-1-LifseaOS.conf -- The 4th partition contains rootfs - -Since x86_64 supports both BIOS and UEFI booting and we employ BIOS -booting for x86_64 (w/o initrd) image, we don't put the grub2 binary -compiled into the 2nd partition. As a result, this bug was not observed. -However, aarch64 only supports UEFI booting.
