Comment 6 for bug 1611287

I think hack is an unnecessarily strong term.

In the Cassandra snap, the config is copied into $SNAP_DATA at runtime (if not already present) [1]. Helper programs are provided for getting, setting, and environment variable lookup (for templating) [2].

Having native support for config will bring consistency with other snapped applications, but otherwise this works quite well.
