cat <<EOF >/tmp/make.conf
# Build and install only FCTARGET kernel.and GENERIC kernels # /boot/GENERIC FCTARGET will be updated installed by freebsd-update(8)default. KERNCONF=FCTARGETGENERIC EOF
sudo install -g staff -o aram /tmp/make.conf /etc
== Create /usr/obj Exclude the kernels from freebsd-update(8) ==
Components src world == Set permissions to build as user == sudo zfs create zroot/usr/obj# assuming you have ZFS
sudo chown aram:staff /usr/obj
== Build and install the kernels ==
Build the kernelkernels:
cd /usr/src
# builds FCTARGETand GENERIC
make buildkernel -j24
Install the kernelkernels:
# installs install FCTARGETinto /boot/kernel (default) and GENERIC into /boot/GENERIC
sudo make -j24 installkernel
sudo make -j24 installkernel KERNCONF=GENERIC INSTKERNNAME=GENERIC
== Load isp(4) driver firmware in /etc/loader.conf ==
As root:
sudo su -
echo ispfw_load="YES" >> /boot/loader.conf
isp(4) is already compiled into the kernel, no need to load it.
== Reboot and test ==
sudo reboot
== Update ==
When updating to the same RELEASE, run freebsd-update(8) to get new source and binaries, then recompile the kernels and reboot.
You can't upgrade to a newer RELEASE without rebuilding the newer kernel first.
