This looks great but in testing it I'm unable to use the 'minimum'
refpolicy recipe in any image. The recipe builds fine but the do_rootfs
fails trying to label the filesystem. I haven't been able to find the
root cause for this yet, but I'm seeing this behavior both before and
after adding this patch so it may be a preexisting issue?
Given all of that, I've merged this patch into master since it doesn't
seem related to the issue I'm seeing. Still, some help in resolving the
issue I'm seeing with the minimum refpolicy recipe would be appreciated.
Thanks,
Philip
