Re-installing after partial install

[finnlewis]

Hey!
I had a pergola installation running, but my computer died, so I think it did not complete. When I try to re-run the installation it tells me pergola is already installed.
Is there an easy way to do a re-provision to make sure everything is as it should be?
Is it as simple as running the puppet.py script?
Cheers.
Finn,
