Hmm... I've been using a "plain old partition" for /boot (with
everything else in LVM) for "ever", originally because the boot loader
was not able to read LVM, and later out of habit.  I was thinking of
finally moving /boot into an LV to make things simpler, but I see that
it'd still be playing with fire (AFAICT booting off of LVM was still not
supported by U-Boot either last time I checked).  🙁
