Super clear. Non-FAT XBOOTLDR is permitted. Non-FAT EFI file system drivers to provide firmware-level support for a file system, is permitted. If Boot Loader Spec aims to constrain the UEFI spec, then it needs to use language that does that. >Of course, I regret having granted the flexibility, that > was a mistake. What about fixing the spec to reflect this? Because then the present behavior is a legitimately a bug and can be reverted to use the generic Linux partition type GUID, or something else. And stop proliferating non-FAT XBOOTLDR. -- Chris Murphy -- _______________________________________________ devel mailing list -- [email protected] To unsubscribe send an email to [email protected] 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/[email protected] Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
