Good. It would be important though to define and document the best way
to configure a pxelinux setup: empty bootfile name, bootfile empty (or
not existent) or a special file format for the bootfile content (like
'PXE0' in EBCDIC). The former two carry the danger of accidentally
enabling the pxe-style boot process.
