What "fork test"? "test" is a builtin, no?
Don't we have a decent parser anywhere in the root filesystem?
*sigh*. Here we go. The beginning of the end. Now we're gonna need
/usr mounted right away.
This is not acceptable for a BSD.

How far are we going to degenerate? /usr does NOT belong on root.
Run HP-UX or Solaris or maybe IRIX if that's better for you.

pmatch would be good. I wonder if perhaps a case statement instead of
an if [ ... ] would be better.
BSD: safe ports in a storm.
