EFI/FedoraA EFI/FedoraB NVRAM bootorder uses A then B Update the bootloader in EFI/FedoraB At any point of failure, only the EFI/FedoraA bootloader path is used. Once everything in EFI/FedoraB is committed to stable media, set bootnext FedoraB. If the boot fails, automatic failback to FedoraA. If the boot succeeds, bootupd can change bootorder. B then A. ? -- Chris Murphy _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org 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@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
