Is there any man page, etc. that describes the format and
syntax for the /boot/kernel.conf file?  The one that got
installed in my 4.6 system appears to be doing something with
certain devices or kernel modules:

di sn0
di lnc0
di ie0
di fe0
di cs0
di bt0
di aic0
di aha0
di adv0
q

but when the machine boots up, it complains:

config> di sn0
No such device: sn0
Invalid command or syntax.  Type `?' for help.
config> di lnc0
No such device: lnc0
Invalid command or syntax.  Type `?' for help.
config> di ie0
No such device: ie0
Invalid command or syntax.  Type `?' for help.
config> di fe0
No such device: fe0
[...]

and so on. If I try replacing kernel.conf with an empty file,
then at boot time I get dumped into the kernel configuration
utility, which I have to exit manually, configuration unchanged.  

I suspect that kernel.conf could be doing something useful, if
I just knew how to use it properly.  However, I can find no
documentation on how to manipulate this file.

This is probably devices you disabled when installing FreeBSD

This is the devices that no longer can be disabled (probably because
you have compiled a custom kernel that no longer have theese devices)

Remove everything except the last row, and you should be fine...

A little of this can be found in loader(8).

You should be able to remove /boot/kernel.conf all together.
