I do know the USB stuff changes but I wasn't sure about the others.  I 
would think the main drives in a system would come first but one could 
never make that promise.  I'm giving serious thought to using the 
labels.  It would also mean that I don't have to remember what partition 
is what.  Currently I would mount and then list what is in the directory 
to see what is in it and figure out what it is.  With the labels 
feature, even fdisk would tell me what is what.

This would be a good time to move the OS to a new drive.  If things work 
out, run from the new drive.  If things blow up, boot the old drive with 
the old kernel, old fstab and other settings.

Thanks.
