going from 6.2 to 6.3 and custom kernel

[Zbigniew Szalbot]

Hello,

I thought I would try to upgrade from 6.2 to 6.2-Release now that it
is officially avilable. However, I do have custom kernel on my
machine. And when using advice written by Colin (thanks!)
http://www.daemonology.net/blog/2007-11-10-freebsd-minor-version-upgrade.html
I get this warning:

WARNING: This system is running a "szalbot" kernel, which is not a
kernel configuration distributed as part of FreeBSD 6.2-RELEASE.
This kernel will not be updated: you MUST update the kernel manually
before running "freebsd-update.sh install".

How do I update the kernel manually then?

Do I have to fetch the latest source and then follow the advice given here?

Thanks!
