I guess that shows how unfamiliar I am with UEFI boot Fedora. You would 
encrypt /boot to ensure that your boot images have not been tampered with, or  
config files haven't been read by somebody other than the end user.

If I'm not mistaken, XFS is the default used on RHEL, but ext4 is still used 
for /boot in Fedora, by default.

Is there a notable benefit to using that over GRUB2, which already has support 
on both UEFI and BIOS?
