RE: Multiple kernelsHi
It is all in the FreeBSD handbook.
You need to cvsup your source, and do a make world. Then compile a new =
4.2 kernel.

Thnxs a lot,=20
Now I have another question :)=20
There's not really a clear how-to out there on upgrading a freeBSD =
system (I didn't install 4.1, someone else did) I've seen warning about =
not buliding a new (ie 4.2) kernel from a system running 4.1. I don't =
really understand, how else are you supposed to build a 4.2 kernel? Or =
am I just dumb and not understanding this warning?
Thnx,=20

You can load that kernel, but it will not work. Basically you can't =

that. In FreeBSD, the kernel is tightly integrated with the rest, and =
must have the same version. This is generally helpful and provides=20
much of FreeBSD's stability.=20
If you have compiled something into your 4.1 kernel that you =

then you'll have to put that into a new kernel config file for 4.2 and =
