Good question.  Not exactly: it's counting everything containing "BSD"
as "FreeBSD".  Ugh.  I agree that this is misleading.  How about we
change the graph legend to "BSD"?  (Unfortunately, we cannot
distinguish easily between the other BSDs in that graph, because we'd
have to re-import the archives since 2007.)

Note that your query above is not entirely correct, either.  You're
overcounting relays publishing more than one descriptor, whereas
Metrics only counts descriptors being referenced from the consensus.
The latest numbers from Tor metrics are:

2016-01-05,,,,Darwin,,22,
2016-01-05,,,,FreeBSD,,371,
2016-01-05,,,,Linux,,6384,
2016-01-05,,,,Other,,9,
2016-01-05,,,,Windows,,387,

See https://metrics.torproject.org/servers-data.html

Thanks for reporting.  A Trac ticket in component Metrics would have
worked, too, but reporting on this list is also fine.

All the best,
Karsten
