Code review comment for lp:~bcsaller/pyjuju/lxc-omega

Looks good to me, some minors

[0] Please use self.juju_home as the base for the lock

762 + lockfile = FilesystemLock(os.path.join(
763 + "/tmp/", "%s.lock" % container_template_name))

[1] I'd prefer the master template to be namespace'd to the environment, it makes its cleanup automatic (if it gets broken), and allows divergence in series across environments.

[2] There's a few minor style violations, mostly of the over 80 col variety, ie.

+ if self._public_key:
+ args.insert(1, "JUJU_PUBLIC_KEY=%s" % pipes.quote(self._public_key))
