>Description:
Netboot programs only work with "aout" kernels,
and it is not possible create an "aout" kernel in version 4.0.
A kernel in this format is necessary for diskless boot process.

In previous versions of FreeBSD, the line:

	makeoptions KERNFORMAT=aout 

could be included in the kernel configuation, but now this option
is meaningless for FreeBSD4.0	
>How-To-Repeat:
Follow the steps for creating a diskless system.
[
you can find the tutorial for doing this in:
http://people.FreeBSD.org/~fsmp/HomeAuto/diskless/net_dl23.html
]

Try to load the kernel with any of the netboot programs,
and you will get the following error message:

		Loading /kernel...
		Bad executable format!

>Fix:
Somebody has to create a "netboot" program that handles 
"elf" kernels.
