Summary:	Handbook doesn't properly document booting other kernels

Description wdr 1999-12-24 01:40:00 UTC

The FreeBSD Handbook suggests that the proper way to boot to an old kernel
(after mis-configuring an kernel rebuild, etc.) is to specify the name of
the old kernel at the boot prompt.  This is not correct in 3.4-STABLE
(and probably hasn't been for some time before 3.4-STABLE).

Fix: 

The proper method to boot an old kernel is to press any other key where
asked to "Press Enter to boot [kernel], any other key for boot prompt", then
type:

unload

load kernel.old

boot

I'll volunteer to re-write this section of the Handbook, if no one else is
already in charge of this.
How-To-Repeat: Bugger your kernel configuration into an unbootable state, then try to
load an old kernel using the instructions in the handbook.

No one else is already in charge of this... thanks for volunteering. . .

Is the documentation still not sufficient?  I added to 
http://www.FreeBSD.org/handbook/boot-loader.html a while back, and I 
consider it sufficient.
