Do you plan to support Indigo on older Ubuntu versions (like 13.04 or
12.04) as well? Point is, that the normal migration tactic is to have
both ROS versions installed and switch them to the new version one ofter
the other. At the moment this wouldn't be possible, as Hydro is only
available until 13.04 (cf. [1]), whereas Indigo starts with 13.10.
Initially the plan was to support Hydro on 13.10 (see [2]), but maybe it
would be easier to support Indigo on an older version.

Having multiple versions installed was always a selling point for ROS
(given that it's so monolithic), so I think we should really work on
providing upgrade paths to our users.

Cheers Jochen
