Possibly in some cases, but this is a fresh install of 10 from
FreeBSD-10.0-RELEASE-amd64-memstick.img. I've recompiled/reinstalled the
stage 2 bootcode from installed source (boot with the install media, `make`
in zroot/usr/src/sys/boot). The generated gptzfsboot is identical according
to cmp. Possible it's a regression from 9.2...

Ah, I should mention. In the list of "Things I've Tried", we can also
include "Install from 9.3 media", which failed with the same error.
