OK, thanks. Yes, in the last post of that thread Nilesh states

"Since I use grub2-mkconfig to generate the configuration, it's there
with UUID, but it works with LABEL as well, I have tried it.
Also, *don't* build your kernel *without* initramfs, because the
kernel by default doesn't support mounting by LABELs or UUIDs (I think
so, I've had failures w/o initrd)."

While I don't know Nilesh's background, I have no reason to really
doubt what he says here I seem to find a lot of posts on the web where
people mount using UUID and they aren't clear as to whether they have
an initramfs or not.

I'll consider this solved for now with one caveat that it's unclear
when you build the initramfs what tools have to be placed within it to
make the following true.

1) No initramfs - mount by device name only

2) With initramfs - mount by device name, label or UUID.

Thanks VERY MUCH for taking the time to find this. I'm removing the
offending option from my grub.config file.

Cheers,
Mark
