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.
