Use SNAP_ instead of SNAPP_. All SNAPP_* variables are deprecated.

You might be interested in the snapcraft project. I'll let others comment on it.

You can put it anywhere in your app-specific directories. If it is read-only
SNAP_APP_PATH is fine but if it is meant to change, use SNAP_APP_DATA_PATH.

No, your logging should be under SNAP_APP_DATA_PATH somewhere.

Yes, snapcraft should be able to do this for you as well since you are able to
reuse debs from the Ubuntu archive. Again, I'll let others comment.
