In Fedora Linux default partitioning for all but Server, it is possible to reconfigure existing systems to UEFI. Fedora Server is screwed because they use XFS and you cannot shrink an XFS volume. Fedora < 33 used ext4 by default, and you can do offline shrink and open up space for an ESP. In Fedora >= 33, ext4 is still used for /boot and you can resize that. Alternatively, the Btrfs / can be resized while the system is running to make room for an ESP. It wouldn't be difficult to provide a tool to make the conversion possible as long as you didn't use XFS. Fedora Cloud 35+ is configured in hybrid mode, so you can seamlessly switch between BIOS and UEFI. Fedora Server users *must* fully reinstall, because there's no way to make space for an ESP and reconfigure things. -- 真実はいつも一つ！/ Always, there's only one truth! _______________________________________________ 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 on the list, report it: https://pagure.io/fedora-infrastructure
