This was developed because we always want to use the PXE-enabled network card as our first boot device.

So we make a link in the ''/tftpboot/pxelinux.cfg'' directory to a pxe configuration file which instructs that it has to fetch the kernel and root filesystem from our boot server, eg:  {{{ 0A000A02 ---> default.node_install (10.0.10.2) }}}
