Looks good - here's another example which should be fixed by using a combination of hostname and creation date:
- Install to RAID1 pair
- Disconnect one half
- Reinstall on the other half (new UUID)
- Connect both halves
- Boot
- Ugliness may ensue
FYI - This is a common telco approach to upgrades - backup, break the mirror, fresh install on one half, restore databases, attach mirror. Or on a bad upgrade, revert to the "good" half of the mirror.
