jumpstart server kernel config

[todgillespie at todgillespie.com]

Hi.  In the jumpstart guide, here,

http://www.freebsd.org/doc/en_US.ISO8859-1/articles/pxe/bootstrap-config.html

it says to 

"Compile a custom kernel for the clients (particularly to avoid the device 
config screen at boot) and stick it in /usr/tftpboot."

How do I do that?  I don't see a relevant setting in my LINT kernel 
config.  Also, will I be okay to just use the GENERIC instead?  Why is 
this important?

Any help is much appreciated.  Thanks!
