version of such. Differences in filesystems generated were found to be
from 1) sbwrite with the "all" parameter 2) removal of writecache. The
sbwrite call was made to perform as the original version, and otherwise
this was checked against a version of newfs with the write cache removed.
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.
