33.Nd dynamic kernel linker facility
34.Sh DESCRIPTION
35The LKM (Loadable Kernel Modules) facility has been deprecated in FreeBSD
363.0 and above in favor of the
37.Nm
38interface.
39This interface, like its
40predecessor, allows the system administrator to dynamically add and remove
41functionality from a running system. This ability also helps software
42developers to develop new parts of the kernel without constantly rebooting
43to test their changes.
44.Pp
45Various types of modules can be loaded into the system.
46There are several defined module types, listed below, which can
47be added to the system in a predefined way. In addition, there
48is a generic type, for which the module itself handles loading and
49unloading.
50.Pp
51The
52.Tn FreeBSD
53system makes extensive use of loadable kernel modules, and provides loadable
54versions of most filesystems, the
55.Tn NFS
56client and server, all the screen-savers, and the
57.Tn iBCS2
58and
59.Tn Linux
60emulators.
