Note: status uneventful with a different snapshot is kinda unexpected for me. Not something drastically problematic though. I'll dig in at some point.
@ardumont: did you load the same sources.json? Because http://guix.gnu.org/sources.json is refreshed every X hours and some stats of the commits after 2018-12-05 (v0.16.0) says mean at 21 and median at 13, both per day. And since loading requires ~1h15min, you need some luck to read the same son file twice.
