Code review comment for lp:~chipaca/ubuntu-push/client-constructor

The other way of doing it would be to leave the client interface as is, and add the ability to config to do substitutions (so that the database path can be specified as "$xdg_data_dir/u-p-c/levels.db" or somesuch), or have a special value such as "default". I don't like these alternatives much, but maybe there's one I'm missing; the con of this is that it'll lead to more mixing private and public attributes in the session config.
