My biggest gripe with UEFI Linux systems is Raid-1 with mdraid. With legacy it's quite easy, set up the mirror, install grub on every partition, and you're done. With UEFI it's far more complicated, having to manually clone the EFI boot partition and then manually add it as part of the EFI chain. You have to remember to redo this whole process if you ever change a disk. Does anyone have a better way to do it?
