Aha, so UFS_EXTATTR is not enabled by default in NetBSD-6.1.2. That was
not immediately clear from the MESSAGE.NetBSD below.

I'll do that, assuming this is one of the kernels that should work:

http://ftp.nluug.nl/NetBSD/NetBSD-7.0/amd64/binary/sets/kern-GENERIC.tgz

Or, maybe I just re-install my VM with NetBSD-7.0 now thats out.

Thanks!
