29.Dt KLDCONFIG 8
30.Os
31.Sh NAME
32.Nm kldconfig
33.Nd display or modify the kernel module search path
34.Sh SYNOPSIS
35.Nm
36.Op Fl dfimnUv
37.Op Fl S Ar sysctlname
38.Op Ar path ...
39.Nm
40.Fl r
41.Sh DESCRIPTION
42The
43.Nm
44utility
45displays or modifies the search path used by the kernel when loading modules
46using the
47.Xr kldload 8
48utility or the
49.Xr kldload 2
50syscall.
51.Pp
52The following options are available:
53.Bl -tag -width indent
54.It Fl d
55Remove the specified paths from the module search path.
56.It Fl f
57Do not display a diagnostic message if a path specified for adding is
58already present in the search path, or if a path specified for removing
59is not present in the search path.
60This may be useful in startup/shutdown scripts for adding a path to
61a file system which is still not mounted, or in shutdown scripts for
62unconditionally removing a path that may have been added during startup.
63.It Fl i
64Add the specified paths to the beginning of the search path, not to the end.
65This option can only be used when adding paths.
66.It Fl m
67Instead of replacing the module search path with the set of paths
68specified,
69.Dq merge
70in the new entries.
71.It Fl n
72Do not actually change the module search path.
73.It Fl r
74Display the current search path.
75This option cannot be used if any paths are also specified.
76.It Fl S Ar sysctlname
77Specify the sysctl name to use instead of the default
78.Va kern.module_path .
79.It Fl U
80.Dq Unique-ify
81the current search path - if any of the directories is repeated one
82or more times, only the first occurrence remains.
83This option implies
84.Fl m .
85.It Fl v
86Verbose output: display the new module search path.
87If the path has been changed, and the
88.Fl v
89flag is specified more than once, the old path is displayed as well.
90.El
91.Sh FILES
92.Bl -tag -width indent
93.It Pa /boot/kernel , /boot/modules , /modules
94The default module search path used by the kernel.
