I think this is occurring because the test is being run as "root".
I don't know how common that is in build environments, but it's not something that I have or think I should have in my build (sbuild) or test (autopkgtest) environments.
Is there some flag we could use to tell reproducible-builds to build this package as a regular user instead of root?
If not I might have to patch the test suite to work around some of the logic in there, which I'm not too excited about.
Perhaps an alternative would be to add "puppet-agent" as a build dependency, because that package will create a "puppet" user in the environment.
