I don't think this is possible. Even / has a parent directory
(/.. being the only loop in the directory graph allowed).
If you want to create a process that has no working directory, you can
do this by, for example,
mkdir("/tmp/foo");
chdir("/tmp/foo");
rmdir("/tmp/foo");
which will make it impossible to create files in dot (./). This can
cause other problems as many programs assume they can walk up to
root.
The jail code in -current may also be of interest.
