>     zdb is very handy for diagnosing problems with a pool in a safe and
>     quick way. When a pool is in a bad shape, we often want to disable some
>     fail-safes, or adjust some tunables in order to open them. In the
>     kernel, this is done by changing public variables in mdb. The goal of
>     this feature is to add the same capability to zdb and ztest, so that
>     they can change libzpool tuneables from the command line.
