Best practices for using Bazaar to version control your install

Hello,

I’m wondering how to best use Bazaar for personal version control of my Drupal installation. I'd like to version control the changes that I make to my configuration. A few questions: kinda basic :)

• Where do you initialize Bazaar? There seems to be Bazaar branch already in at the web root.
• Does it make sense to initialize at the server root? Which directories do you place in the Bazaar ignore file?
• What (which directories/files) should I use bzr to version control? Does it make sense to add the whole www directory for instance? I had a problem when committing my modules directory. It seemed to hang.
• What’s the best way to store my branches locally?

Thanks
