The strangeness continues:  installation from F9 Beta DVD was as above 
and fstab was created with /dev/sdd5, not some UUID, as swap.  Somewhere 
along the line after one of the rawhide updates, the drive sequence has 
changed back to the original.  I discovered this when I saw a msg about 
a swapon error and saw /dev/sdd5 in fstab and fdisk shows it is now 
/dev/sda5.  Swaps used to be created with labels which would have 
avoided this issue.

The question now becomes why wasn't /dev/sdd5 UUID used to id the swap 
device during the original installation?  Or do they pertain to swap 
devices?  I see that blkid /dev/sda5 returns only:
/dev/sda5: TYPE="swap".
