cant login after installing custom kernel (4.1)

by Heiko Brau » Sat, 30 Sep 2000 04:00:00

Hi,
first of all, Im an absolute novice to FreeBSD.
My problem is that i have made my own kernel over night (FreeBSD 4.1),
all like said in the handbook (make world, buildkernel , installkernel),
and when i did a reboot this morning, i can do no more login (even as root).
I tried to boot the old kernel, but it's the same there.
So, what did i make wrong (and do i have to do a new install)?

Thanks for any response.

1. Building a custom kernel in 4.1

Hello,
I am familiar with the procedure of building a custom kernel under
FreeBSD3.3 but having a lot of difficulty when trying to follow the
procedure for FreeBSD4.1. Can anyone summarize the exact steps to build a
custom kernel under FreeBSD4.1(the documentation is a little confusing)?

I am trying to build a custom kernel with a label module (from NIST) and the
build fails while trying to link with some of the function pointers of that
module. Below are the errors I get:
