The new userpic factory requires MogileFS in order to work and does not error out real gracefully if Mogilefs is not there. No biggey, I wanted to turn MogileFS on anyway. After reading up I think I see how to create the DB, create the storage devices, user mogadmin to populate the DB, set up the config files for mogstored and mogilefsd, start the daemons.
The questions: Is there any hidden gotcha that will prevent this from all working on the same machine (obviously a dev env not a production env) if I set it up with only one storage device?
