This is a bug in supermin.  But as a simple workaround you could
create a file which creates the required directory /etc/rc.d/init.d
before hostfiles is loaded.  Something like this:

  mkdir -p /tmp/etc/rc.d/init.d
  cd /tmp
  find etc | cpio --quiet -o -H newc > /tmp/00-rc.img
  cp /tmp/00-rc.img /usr/lib64/guestfs/supermin.d/

Note files in supermin.d are visited in lexicographic order.
