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.
