Yes, I've continued these builds for trunk - I just haven't gotten
around to updating the above page and announcing them.  You can see
the results of these daily bulk builds on the pkgsrc-bulk@ list, e.g.:

  http://mail-index.netbsd.org/pkgsrc-bulk/2016/08/28/msg013079.html

32-bit and 64-bit take it in turns each day, just in case a build
takes >24 hours.  The packages are synced to:

The above builds are performed on 7-core 7GB KVM instances in the
Joyent cloud, using 7 concurrent chroots, and are generally done in
less than 12 hours.  I think a full from-scratch build takes around 24
to 30 hours.

Our KVM implementation definitely isn't optimal, so you will probably
see faster builds than this on native hardware, as well as being able
to bump up the concurrency.
