Upgrading kernel

[olav]

I just read the manual for updating FreeBSD, I have a custom kernel where I've enabled vm.kmem_size to be larger than 512M. How to I proceed to update that kernel?

The same way you would any other kernel.

You're not using a linux derivative. Never update just the kernel. Make sure world and kernel are in sync!

Handbook: 24.7 Rebuilding “world”
Handbook: 8.5 Building and Installing a Custom Kernel

vm.kmem_size is a loader tunable, you set it in /boot/loader.conf. No need to compile the kernel.

Oh, I should have mentioned that this is a i386 system. I recompiled the kernel with KVA_PAGES=512
I guess there is a way to update the /usr/src folder for the latest updates and then just recompile and install the new kernel?

Yes, read the handbook.

so I basically run

$freebsd-update fetch 
$freebsd-update install

And then recompile and install the kernel?
