XBOOTLDR must be formated with a filesystem the uefi firmware can read (i.e. vfat in practice) I assume? > > Another problem is that grub2 covers more architectures than sd-boot. > > What is the plan for armhfp, ppc64, s390x? > > sd-boot is uefi only, but it should work fine with any arch that is > supported by uefi.

Using the above partition scheme probably works with sd-boot (instead of grub-efi) too if you tag /boot as XBOOTLDR. The point I was tring to make is that you can install fedora in a way that the disk can be booted in both bios and uefi mode. take care, Gerd _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
