Actually, no.  My fstab uses labels to find and mount the drives, not
UUIDs.  That way I don't have to worry about things like
reformatting-changed UUIDs and other nit-witticisms of the latest
whizzbang new way to screw up a perfectly good working system that
won't get changed out from underneath me.

That was also among the changes I made to the grub.cfg - to use the
labels for the kernel to choose where / was - and that was what
"saved" me on the last go around.

I have since run update-grub (of course) to ensure that this will be
less likely to clobber me next time.

Thanks to all for your input - it's been helpful.
