fabric command in local context is failing grep command

I'm on OS X using boot2docker. I'm trying to use fabric to simplify running docker containers for our QA's.

Running this command...

  containerFound = fab.local('docker ps -a | grep nodejs', capture=True)
  # this didn't work either if fab.local('docker ps -a | grep nodejs').succeeded

generates the following error:

Fatal error: local() encountered an error (return code 1) while executing 'docker ps -a | grep nodejs'

Is this an issue using boot2docker. I tried using sudo as well but nothing. I believe boot2docker runs as root anyways so sudo isn't needed.

In Fabric 1.3.2 at least, you can recover the exception by catching the SystemExit exception. That's helpful if you have more than one command to run in a batch (like a deploy) and want to cleanup if one of them fails.
