mdconfig(8), because we need a disk to work on.
o Extend the number of tests now that we have a disk.
o Simplify the driver. All parameters are ASCII strings now.
The testsuite is based on a simple driver program that builds a
request from the arguments passed to it and issues the request to
Geom. The driver emits FAIL with the error string or PASS depending
on whether the request completed with an error or not. A -v option
has been added to the driver and causes the request to be dumped.
The -v option to prove(1) controls the -v option to the driver.
The testsuite itself contains a hash of which the key constitutes
the arguments and the value is the expected result.
