Install a Custom Kernel with Extensions.
1. Download the FreeBSD 11 Distribution Sources.
```
svn co https://svn0.us-west.freebsd.org/base/stable/10 /usr/src

  Here Take a Break Because you need to Wait for a Long Wile…
2. Make a New Kernel Configuration File.
```
cd /usr/src/sys/amd64/conf
```
  If Do Not Know How to Proceed then you should Simply use the Default Config File:
```
cp GENERIC MYKERNEL
```
3. Build a Custom Kernel.
```
cd /usr/src
```
```
make -j `sysctl -n hw.ncpu` buildworld
```
  Here Take another Time-Out Waiting for a Wile…
```
make -j `sysctl -n hw.ncpu` buildkernel KERNCONF=MYKERNEL
```
  Last Keep Patient and Still Wait Again for a While until the Process is Achieved with:
  Kernel build for MYKERNEL completed
4. Lastly Install the New Kernel.
```
make installkernel KERNCONF=MYKERNEL
```
