At the moment, there is only a crumpled UEFI image flying across the screen, without any intervention option (which is OK for SBC, but probably not for a „real“ server). > U-Boot does have a UEFI shell, though for our purposes, it's not that important. U-Boot would merely allow us to jump into an environment that executes the boot manager EFI binary (grub2, rEFInd, sd-boot). If it's possible, it's something Fedora Cloud would probably adopt pretty quickly. -- 真実はいつも一つ！/ Always, there's only one truth! _______________________________________________ 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 Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
