.Nd display or modify the kernel module search path
|
|
.Sh SYNOPSIS
|
|
.Nm

.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility
|
|
displays or modifies the search path used by the kernel when loading modules
|
|
using the
|
|
.Xr kldload 8
|
|
utility or the
|
|
.Xr kldload 2
|
|
syscall.
|
|
.Pp
|
|
The following options are available:
|
|
.Bl -tag -width indent
|
|
.It Fl d
|
|
Remove the specified paths from the module search path.
|
|
.It Fl f
|
|
Do not display a diagnostic message if a path specified for adding is
|
|
already present in the search path, or if a path specified for removing
|
|
is not present in the search path.
|
|
This may be useful in startup/shutdown scripts for adding a path to
|
|
a file system which is still not mounted, or in shutdown scripts for
|
|
unconditionally removing a path that may have been added during startup.
|
|
.It Fl i
|
|
Add the specified paths to the beginning of the search path, not to the end.
|
|
This option can only be used when adding paths.
|
|
.It Fl m
|
|
Instead of replacing the module search path with the set of paths
|
|
specified,
|
|
.Dq merge
|
|
in the new entries.
|
|
.It Fl n
|
|
Do not actually change the module search path.
|
|
.It Fl r
|
|
Display the current search path.
|
|
This option cannot be used if any paths are also specified.
|
|
.It Fl S Ar sysctlname
|
|
Specify the sysctl name to use instead of the default
|
|
.Va kern.module_path .
|
|
.It Fl U
|
|
.Dq Unique-ify
|
|
the current search path - if any of the directories is repeated one
|
|
or more times, only the first occurrence remains.
|
|
This option implies
|
|
.Fl m .
|
|
.It Fl v
|
|
Verbose output: display the new module search path.
|
|
If the path has been changed, and the
|
|
.Fl v
|
|
flag is specified more than once, the old path is displayed as well.
|
|
.El

|
.Sh FILES
|
|
.Bl -tag -width indent
|
|
.It Pa /boot/kernel , /boot/modules , /modules
