You can prevent that from happening by using a specific configuration
file for every machine you install. The name of the file is based on the
HEX of the IP address that the machine will get from DHCP when you PXE
boot.
E.G. have a file called 0A641901 for a machine with IP 10.100.25.1
You also have a default file in your pxelinux.cfg file with the
following in it:
# generated by fai-chboot
default fai-generated
label fai-generated
localboot 0
You then have a simple PHP script to move the boot config to,
say, .disabled and when the machine reboots it will boot from local
disk.
Example PHP script:
<?php
if (isset($_SERVER['REMOTE_ADDR']))
$ip = $_SERVER['REMOTE_ADDR'];
else
$ip="192.168.1.203";
$long=ip2long($ip);
$hex=dechex($long);
$hex=strtoupper($hex);
print "$hex\n";
$origin = "/var/lib/tftpboot/pxelinux.cfg/$hex";
$destination = "/var/lib/tftpboot/pxelinux.cfg/$hex.disabled";
passthru("mv $origin $destination");
You can call this script from your preseed/late_command target
