Initial STU 1 Ballot Changes (version 1.0.0-ballot)
This is the first ballot of this implementation guide in this form, but the content has been balloted and published in multiple prior implementation guides, including:
The following changes were made as a result of ballot comments received in the September 2023 ballot of the Canonical Resource Management Infrastructure IG.
