Thoughts or other suggestions anyone?

This is a case where a very small /boot partition is still a very good
idea... 50-100MB is a good choice (some initramfs generators require
quite a bit of space under /boot while generating the initramfs image
esp. if you use distro-provided "contains-everything-and-the-kitchen-sink"
kernels, so it is not wise to make /boot _too_ small).

But if you do not want /boot to be separate a moderately sized root
partition is equally good. What you want to avoid is the "whole disk is
a single partition/file system" kind of setup.

Yes, we actually have a separate (smallish) boot partition at the front of
the array.  This does reduce the at-risk window substantially.  I'll have to
ponder whether it reduces it close enough to negligible to then ignore, but
that is indeed a good point to consider.
