I tried the second version:

      (cd / ; /rescue/gzip -d  < $j | /bin/pax -r -p e )

but it doesn't work. What does work is this:

      (cd / ; /rescue/gzip -d < $j | /stand/cpio --extract -d )

So apparently this 'pax' solution is not as straight forward
as it seems.

However, after the boot up has succeeded, I can do manually:

  # cd /var
  # rm -rf *
  # /rescue/gzip -d < /conf/base/var.cpio.gz | /bin/pax -r -p e

and the basic /var structure is there again. So it works on
a running diskless system; why not during bootup?
