I've done that, but Buildbot is giving me the following error:

    git fetch -t g...@bitbucket.org:myproject/myproject.git branch1
     in dir
/usr/local/myproject/src/buildbot/worker/myproject_runtests/build (timeout

Presumably, the problem is that Buildbot is using /home/ubuntu for HOME
instead of /var/lib/buildbot. However, Buildbot is running as the buildbot
user, so I'm unsure why it would be using the ubuntu user's home directory.
How do I fix this?
