That is what it is supposed to do, however it does not do that in my 
experience.  This means that your #!/bin/sh scripts can break on *BSD
which has a real /bin/sh.

Besides, you really need a statically linked /bin/sh, something lacking
from most Linux distros.  With a statically linked /bin/sh, you can boot
with init=/bin/sh to make repairs, if you need to.
