Whatever :-)

An environment variable seems the obvious way to communicate the
information. Give me a version string like 1.24.4 and I'm happy. The
trick is documenting and sticking to the format, so I know if one day
you might throw 1.26.1-alpha6 at me.

So do it if it really is trivial, or if not try not to break the work
around in charm-helpers (parsing the output of
"/var/lib/juju/tools/machine-*/jujud version")
