  My poudriere build did eventually fail as well:

  Trying to do another poudriere build fails almost immediatly with that verify error.

  Your verify errors don't match up exactly.  I've got snapshots from before I started
freaking it out with the sysctl calls and possibly inducing corruption.

  I didn't tweak this system off defaults for block-cloning.  I haven't been following
that issue 100%.
