216 method of updating your system from the latest sources is:
217 .Bd -literal -offset indent
219 make buildkernel KERNCONF=FOO
220 make installkernel KERNCONF=FOO
225 After running these commands a system reboot is required,
226 otherwise many programs which have been rebuilt (such as
229 etc.) may not work with the old kernel which is still running.
231 The build and install order in the
233 section enforces that the new kernel is installed before the new

238 .Dq Nm make Cm installworld
