After my ltsp-build-client --arch i386
All went well, but for some reasons tftpd-hpa wasn't installed there were no /var/lib/tftpboot folder.

So I had to install tftpd-hpa manually. DHCP is working well but it can't find pxelinux.0 file
(it just doesn't exist).

Here is my DHCP server conf.

```
authoritative;

subnet 10.10.10.0 netmask 255.255.255.0 {
    range 10.10.10.20 10.10.10.250;
    option domain-name "example.net";
    option domain-name-servers 10.10.10.1;
    option broadcast-address 10.10.10.255;
    option routers 10.10.10.1;
    option subnet-mask 255.255.255.0;
    option root-path "/opt/ltsp/i386";
    if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
        filename "/ltsp/i386/pxelinux.0";
    } else {
        filename "/ltsp/i386/nbi.img";
    }
}

```

client machines are saying:

```
PXE-T01: File not found
PXE-E3B: TFTP Error - File Not Found

PXE-MOF: Exiting Intel PXE ROM.

```

The question: How to generate the pxelinux.0 file and/or nbi.img file?
There is image though in /opt/ltsp/i386/images/i386.img 
But I'm not sure what's that image for.

TFTP Server is running by: /usr/sbin/in.tftpd --listen --user tftp --address 0.0.0.0:69 --secure /var/lib/tftpboot

the /var/lib/tftpboot folder is empty.

Or **another question**. How to Generate pxelinux.0 and nbi.img file again?
