33 .Nd information on how to build the system
37 system and applications is contained in two different directories,
44 directory contains the
46 sources, which is loosely defined as the things required to rebuild
47 the system to a useful state.
48 It also contains the source for the system documentation, including
53 is a tree that provides a consistent interface for building and
54 installing third party applications.
58 command is used in each of these directories to build and install the
59 things in that directory. Issuing the
61 command in any directory or
62 subdirectory of those directories has the same effect as issuing the
63 same command in all subdirectories of that directory. With no target
64 specified, the things in that directory are just built. The following
65 list provides the names and actions for other targets:
66 .Bl -tag -width ".Cm install"
68 Removes any files created during the build process.
70 Installs the results of the build for this directory.

171 method of updating your system from the latest sources is:
172 .Bd -literal -offset indent
174 make buildkernel KERNCONF=FOO
175 make installkernel KERNCONF=FOO
181 must be replaced with the name of the kernel configuration file from which
182 the kernel should be built.
187 can be set to the name of the kernel to build;
194 commands can be omitted.
196 After running these commands a system reboot is required,
197 otherwise many programs which have been rebuilt
202 may not work with the old kernel which is still running.
