When given a pool name via -e, zdb would attempt an import. If it failed, then it would attempt a verbatim import. This behavior is not always desirable so a -V switch is added to zdb to control the behavior. When specified, a verbatim import is done. Otherwise, the behavior is as it was previously, except no verbatim import is done on failure.
