200 pts. Build a Custom Kernel .stp 002

The kernel is the core of a *nix based OS. By default FreeBSD is installed with a GENERIC kernel. The GENERIC kernel supports a wide range of hardware devices; many of which you do not need.

In this project we will build a custom kernel to support only the devices we need.

The kernel source code and configuration files live in /sys. If you do not have a /sys directory on your system it means you did not install the source for the kernel.

If this is the case fire up sysinstall and download the kernel source from either your FreeBSD iso or from an ftp site.

• From sysinstall select Configure | Distributions | src | sys -> then install. You can now follow the instructions in the FreeBSD Handbook to build your custom kernel.

If you have questions about some of the hardware/device/service options call me over and we can discuss them and decide whether or not to include them in your custom kernel.
