As someone who has run /boot on raid1 for years, I think his idea in the article of keeping them synchronised in userspace at update time (ie rsync) is better. There is no reason to need realtime raid1 kernelspace sync when /boot changes only monthly.

One good reason is that mdraid takes care of syncing automatically, no need to set up rsync on every update of /boot.
