pkg-static was also the first thing I was looking at when trying to 
recover. But it was unusable as well.

Thanks to Dan's posted log 
(https://users.isc.org/~dmahoney/failedupgrade.txt) we have the error 
message, I couldn't recall from memory.

# pkg-static install -f pkg
pkg-static: Unable to determine the ABI, none of the ABI_FILEs can be read.
pkg-static: Cannot parse configuration file!

I also tried pkg-static add with a few files in /var/cache/pkg, until I 
came up with my plan to untar those files.

Maybe there would have been a way to get pkg-static going, but once I 
thought about untaring the .pkg files I stopped looking.

That's an important note for everyone that's affected. I had a 
recent-ish .pkgsave file of master.passwd and groups, luckily.
