I did just that.
copied the sda1 /boot sda2 /swap sda3 / to machine.
Have it booted to my g4l kernel, check all partition report no 
errors.
mount the /dev/sda3 change to /etc run blkid to get the current 
uuids.
modify the fstab to have all the correct uuids.
reboot machine, ad it ends with that message. 
Normal boot would not take 8 minutes.
So the uuids listed in fstab match with what blkid reports.
Talks about by-disk, so don't know were the disk uuid is recorded
blkid doesn't show any uudi for /dev/sda just for the partitions.
