So every installation from an image will have the same UUIDs.
Yes
this is a bad idea, it means you cant ( or will haveto do some work ) if you ever intend to share media. onprem, lesser issue ( likely only when disaster recovery is involved ), but this is a much bigger issue in offprem, where block device mobility is part of the larger picture and taken for granted.
so, we should fix it.

I just finished writing a script to change UUIDs and LABELs. It's changeuuid.py in https://github.com/mndar/rbf/tree/master/commonscripts It doesn't depend on anything else in the repo, so you can just download that script.
Sample Usage:
# just show what is going to change ./changeuuid.py pretend /dev/sdb /tmp/temp/
# actually change ./changeuuid.py change /dev/sdb /tmp/temp/
Refer the README for more details. Let me know if you have any issues.
