+pjdfstest test suite execution is integrated into kyua. This README describes
+how to use pjdfstest in the default configuration (kyua work directory), and
+with a specific filesystem path.
+
+Method 1. Executing with default configuration (kyua work directory)
+
+    1. Elevate privileges:
+       % su -
+    2. cd to the tests directory:
+       % cd /usr/tests/sys/pjdfstest
+    3. Run kyua:
+       % kyua test
+
+   Executing the commands as shown above will run pjdfstest in the kyua work
+   directory. The kyua work directory defaults to a random generated path under
+   /tmp; please see TMPDIR in kyua(1) for more details on how the temporary path
+   is chosen with kyua.
+
+Method 2. Executing with a specific filesystem path (in this case /mnt)
+
+    1. Elevate privileges:
+       % su -
+    2. cd to the tests directory:
+       % cd /usr/tests/sys/pjdfstest
+    3. Run kyua:
+       % env PJDFSTEST_TEST_PATH=/mnt kyua test
+
+   WARNING: the above method violates the test program isolation algorithm
+   described in kyua(1); as such, $PJDFSTEST_TEST_PATH must be cleaned up after
+   executing the testcases.
+
+   It's highly recommended that $PJDFSTEST_TEST_PATH be pointed to a sandboxed
+   filesystem, e.g. a small UFS-formatted memory disk or ZFS dataset with
+   quotas enabled, so the filesystem can be easily destroyed after the test
+   execution is complete, and the testcases are properly bounded both in terms
+   of time and space.
