Chris,
After several weeks of schedule hell, I was finally able to work on
this.  The upshot is that the previously installed kernels weren't
available (so I had to pull the more recent available one), I got some
errors on the grub2 commands, and when rebooting into the new kernel I
get several errors:

When entering GRUB:
error: file `/grub2/locale/en.mo.gz' not found

After selecting kernel from the grub menu:
error: invalid magic number.
Loading initial ramdisk...
error: you need to load the kernel first

These were similar errors to the ones I was getting when the problem
first appeared - and yet now things should be installed into the boots
directory on the / partition rather than the separate /boot partition
that seems to have become unloadable.

Does this make any sense?
