From ca2e5c188ee68045b54a86bfefcfd4a75e174221 Mon Sep 17 00:00:00 2001

Subject: Add the undocumented -R option to disable randomness for
 regression-testing.

Add a couple of simple regression tests accessible with "make test", they
depend on the md(4) driver.

FYI I have also tried running the test against a week old newfs and it
passed.
