repartitioning effectively mandates a reinstall. As a result, we don’t drop support for existing Legacy BIOS systems yet, just new installations.
This is where I have a problem with this, the fact that there is no upgrade path - virtually my entire installed base of Fedora is running legacy BIOS and not being able to upgrade them will be something of a headache.
Is it actually true though? You need to be able to find some space for an EFI partition but assuming that can be done is there some other reason you can't migrate from BIOS to UEFI booting?
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.
I generally do my own partitioning rather than using the default, and all my systems are ext4 so sounds like it's not necessarily impossible.
I'm actually looking at stealing swap on some of them, or just growing disks for VMs.
If you have a swap partition, that's the easiest place to steal from, indeed!
