* Substitute the path of the system derivation directly in the stage 2

init script.  This removes the need for the `systemConfig' boot
  parameter; `init=<stage-2-init>' is enough.  However, the GRUB menu
  builder still needs to add `systemConfig' to the kernel command line
  for compatibility with old configurations.
