Re: Problem with initially getting grub menu file over network

[Braden]

Well, I managed to figure out my problem.  Thanks to those who offered 
their advice.  The following is the simple solution.

Basically, I forgot that the DHCP request that PXE does is not used by 
grub.  Grub does its own DHCP request as well.  Unfortunately, the way 
I had my dhcpd.conf file,

> class "pxeclients" {
>   match if substring (option vendor-class-identifier, 0, 9) = 
> "PXEClient";
>
>   option option-150    "(nd)/grub.lst"; # This isn't a good idea,
>                                         # given the above conditional.

>   filename             "/pxegrub";
>   option host-name     "default-pxe-client";
>
>   option vendor-class-identifier "PXEClient";
>   vendor-option-space PXE;
>   option PXE.mtftp-ip 0.0.0.0;  # Gets the client's attention
> }

the option 150 was only being sent for the request made by PXE, as I 
included it only in the section conditional on the "PXEClient" vender 
class identifier string.  So the option 150 was only being sent on 
PXE's request, but not on pxegrub's request.  OOPS!

So I just moved the option 150 outside of the conditional "pxeclients" 
class, and then pxegrub downloaded the menu file from the TFTP server 
just fine.

I hope someone can learn from my mistake.
