I mount /tmp as a tmpfs on all of my FreeBSD systems, and have been
tracking stable/10 daily for some time (ref.
http://www.catwhisker.org/~david/FreeBSD/history/).

I have not seen anything like the above.

I am presently running:

FreeBSD g1-245.catwhisker.org 10.2-BETA2 FreeBSD 10.2-BETA2 #96 
r285668M/285670:1001519: Sat Jul 18 04:07:25 PDT 2015     root at
g1-245.catwhisker.org:/common/S2/obj/usr/src/sys/CANARY  amd64

on my laptop; on the system where I'm reading & writing mail, it's:

FreeBSD albert.catwhisker.org 10.2-BETA1 FreeBSD 10.2-BETA1 #418 
r285410M/285418:1001519: Sun Jul 12 04:37:35 PDT 2015     root at
freebeast.catwhisker.org:/common/S2/obj/usr/src/sys/ALBERT  amd64

I am, however, not using unionfs.

I have a test system available, if that might help (e.g., for trying
to reproduce the problem).

Peace,
david

Good to know. I'm working on creating a new experimental build of OPNSense +
HardenedBSD.

I've uploaded the memstick image that exhibits the faulty behavior at 
https://hardenedbsd.org/~shawn/opnsense/bad_buids/

Thanks,
