Craig, that was a very helpful link from Fedora (I miss Anaconda), 
thanks. It cleared up a few things. When you're just a home user like 
me, you are only as up-to-date as your newest installed distro.

/etc/fstab is set up with UUID's, but none of the partitions have labels 
- still have to figure out how to do that one.

I have now googled for a method to find the UUID of a partition, so I'm 
OK to add a new hard drive. I guess now we replace the a b c method of 
identifying drives with UUID=7dbe1d83-a2e8-4289-8c2b-a4ace8fbd608. 
That's bound to be a lot of fun...

The hard drives are not so bad, I could even put a comment before each 
partition in fstab as to what hdx or sdx partition the UUID is referring 
to, if I want the security blanket of the old names. But I don't have 
the CD/DVD-ROM's all figured out yet. But I'm chipping away at it.

These changes require more skill and knowledge than before - does not 
benefit the average user like me.
