I've always wondered why it was required that my EFI partition be FAT. I've had systems where that partition has gotten messed up and required an fsck from a recovery boot, and it seemed like it should be possible to either do that automatically in some way, but being able to use a filesystem that self-corrects would be nice too (although maybe overkill for the 1 GB or whatever I give it). I guess maybe it would only be possible to perform the fsck if I booted from a different partition, which then could develop the same issue. This does make me wonder how silly it would be to have a duplicate boot partition on each of my machines that I only mount to sync over changes to the real one so I could avoid needing to grab my flash drive when stuff like this happens...
