If you have empty drives anaconda can raid1 everything including the EFI
system partitions using mdadm metadata 0.9. But since the firmware doesn't
know this ESP is an array there is a possibility only one ESP gets modified
which is effectively corruption.
What's really needed is a boot services daemon that manages boot and ESP
volumes. Instead of RAID 1, it keeps them synced. And instead of them
always being mounted persistently, they're mounted on demand only when
they're modified, and only modified by API via the daemon. Of course this
doesn't exist yet. But without it, we've regressed in functionality and
reliability.
