So, properly, we shouldn't have separate boot and EFI partitions? I 
generally separate them so that I can have my boot partition on ext4 
(contains only kernels & initrds), but if I'm not mistaken, the EFI 
partition needs to be FAT32. Hence, two separate partitions. The other 
benefit I've seen is that it keeps other operating systems (in a 
multi-boot environment) from clobbering anything in /boot. Is this not 
the correct way to implement this? If not, how can the expected mount 
points be preserved while allowing for separate partitions? I prefer not 
to use FAT for anything if I can help it.

This is my current setup:

/ - root partition, btrfs
/boot - boot partition, ext4
/boot/efi - EFI partition, FAT32

(FWIW, I've been using rEFInd as my EFI bootloader, which looks for 
/boot/efi/EFI during installation.)

Thanks,
