Upgrading from 7.0 to 7.1

[James Wu]

Hi all,

I'm brand new to the list so forgive me if this has been answered. I 
tried searching the archives and tried googling and didn't come up with 
any results.

I've been wanting to play with setfib multi-routing tables in 7.1, 
however, we have a bunch of 7.0 machines. I thought I'd take a test 
machine and upgrade it to 7.1. Everything went smoothly at first. I 
compiled a custom 7.1 kernel and installed it just fine. Afterwards, I  ran:

freebsd-update fetch
freebsd-update install
to upgrade to the latest 7.0

then:
freebsd-update upgrade -r 7.1-RELEASE
freebsd-update install -r 7.1-RELEASE
freebsd-update fetch
to upgrade to 7.1

now when I do a
uname -a,
I get FreeBSD 7.1-RELEASE-p3 which looks right to me

The problem I'm running into though is that the setfib binary doesn't seem to been added during the upgrade as I don't see it anywhere. 
I took a fresh install of 7.1 and do see it /usr/sbin/, but it's not there for the upgraded version of 7.1. 

I guess at this point, I would like to do a reinstall of the sbin folder if it is possible or somehow get a clean copy of the /usr/sbin/ folder into my upgraded machine. 
Any hints on how to do that?
