179 method of updating your system from the latest sources is:
180 .Bd -literal -offset indent
182 make buildkernel KERNCONF=FOO
183 make installkernel KERNCONF=FOO
188 After running these commands a system reboot is required,
189 otherwise many programs which have been rebuilt (such as
192 etc.) may not work with the old kernel which is still running.
194 The build and install order in the
196 section enforces that the new kernel is installed before the new
