Is it legitimate to redefine d-ng such that if the hash comes from the
filesystem it adds an additional prefix? This will only occur if the
admin has explicitly enabled the trusted_vfs option, so we wouldn't
break any existing configurations. Otherwise, I'll look for the
cleanest approach for making this dynamic.
