    PXE Improvements
    
    - Client view of tftp supplied files is a path relative to dhcp declared
      'filename', in this case, pxelinux.0.  Corrected paths, with a mental
      note to add an admonition about it for the adventurous.
    - dhcpd doesn't accept 'arch' as a predefined option, so we have to
      associate it with an option code and define it. This probably works -
      or at least, dhcpd will run this way.
    - Did not touch EFI/PXE stuff, no viable test process is currently
      available here. Probably needs work.
