In FreeBSD, the kernel is tightly integrated with the rest, and must have the same version. This is generally helpful and provides much of FreeBSD's stability. If you have compiled something into your 4.1 kernel that you want, then you'll have to put that into a new kernel config file for 4.2 and recompile your kernel, if you want to use 4.2 Tim -- /""\ \ / X ASCII Ribbon Campaign - Say NO to HTML in email / \ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message ------_=_NextPart_001_01C0913D.1BDD62A0 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable RE: Multiple kernels

Thnxs a lot,
Now I have another question :)
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,

        If you = have compiled something into your 4.1 kernel that you want,
then you'll have to put that into a new kernel = config file for 4.2 and
recompile your kernel, if you want to use 4.2
