They are old, it's BIOS and MBR, but UUIDs are in use in /etc/fstab. 
And everything Just Works now, the only thing I need to do is move 
'/boot/' from its own md device into '/' so there is space.


`/etc/fstab` excerpt (updated to but not rebooted):
```
# / was on /dev/md2 during installation
UUID=bafdc515-511e-44b9-85d0-e1cd164cc58c /               ext4 
errors=remount-ro 0       1

# /boot was on /dev/md1 during installation
#UUID=21fd376b-fa9a-4dd0-bfa3-f3ca314d0648 /boot           ext4 
defaults        0       2
# 2020-04-07 /boot/ HACK
UUID=21fd376b-fa9a-4dd0-bfa3-f3ca314d0648 /boot.old        ext4 
defaults        0       2
```

And (edited for clarity):
```
