The documentation for this flag leads one to believe that the full path to the module directory is needed. In reality, this flag specifies only the root of the module path.

<title>Description</title>
|
|
|
|
<para>
|
|
<command>modprobe</command> intelligently adds or removes a
|
|
module from the Linux kernel: note that for convenience, there
|
|
is no difference between _ and - in module names (automatic
|
|
underscore conversion is performed).
|
|
<command>modprobe</command> looks in the module directory
|
|
<filename>/lib/modules/`uname -r`</filename> for all
|
|
the modules and other files, except for the optional
|
|
configuration files in the
|
|
<filename>/etc/modprobe.d</filename> directory
|
|
(see <citerefentry>
|
|
<refentrytitle>modprobe.d</refentrytitle><manvolnum>5</manvolnum>
|
|
</citerefentry>). <command>modprobe</command> will also use module
|
|
options specified on the kernel command line in the form of
|
|
<module>.<option> and blacklists in the form of
|
|
modprobe.blacklist=<module>.
|
|
</para>
|
|
<para>
|
|
Note that unlike in 2.4 series Linux kernels (which are not supported
|
|
by this tool) this version of <command>modprobe</command> does not
|
|
do anything to the module itself: the work of resolving symbols
|
|
and understanding parameters is done inside the kernel. So
|
|
module failure is sometimes accompanied by a kernel message: see
|
|
<citerefentry>
|
|
<refentrytitle>dmesg</refentrytitle><manvolnum>8</manvolnum>
|
|
</citerefentry>.
|
|
</para>
|
|
<para>
|
|
<command>modprobe</command> expects an up-to-date
|
|
<filename>modules.dep.bin</filename> file (or fallback human
|
|
readable <filename>modules.dep</filename> file), as generated
|
|
by the corresponding <command>depmod</command> utility shipped
|
|
along with <command>modprobe</command> (see
|
|
<citerefentry><refentrytitle>depmod</refentrytitle><manvolnum>8</manvolnum>
|
|
</citerefentry>). This file lists what other modules each
|
|
module needs (if any), and <command>modprobe</command> uses this
|
|
to add or remove these dependencies automatically.
|
|
</para>
|
|
<para>
|
|
If any arguments are given after the
|
|
<replaceable>modulename</replaceable>, they are passed to the
|
|
kernel (in addition to any options listed in the configuration
|
|
file).

Normally, <command>modprobe</command> will succeed (and do
|
|
nothing) if told to insert a module which is already
|
|
present or to remove a module which isn't present. This is
|
|
ideal for simple scripts; however, more complicated scripts often
|
|
want to know whether <command>modprobe</command> really
|
|
did something: this option makes modprobe fail in the
|
|
case that it actually didn't do anything.

Every module contains a small string containing important
|
|
information, such as the kernel and compiler versions. If a module
|
|
fails to load and the kernel complains that the "version magic"
|
|
doesn't match, you can use this option to remove it. Naturally,
|
|
this check is there for your protection, so this using option is
|
|
dangerous unless you know what you're doing.
|

</para>
|

<para>

This applies to any modules inserted: both the module (or alias) on

When modules are compiled with CONFIG_MODVERSIONS set, a section

|
detailing the versions of every interfaced used by (or supplied by)
|
|
the module is created. If a module fails to load and the kernel
|
|
complains that the module disagrees about a version of some
|
|
interface, you can use "--force-modversion" to remove the version
|
|
information altogether. Naturally, this check is there for your
|
|
protection, so using this option is dangerous unless you know what
|
|
you're doing.

<command>install</command> and <command>remove</command> commands

in the configuration file (if any) for the module specified on the

command line (any dependent modules are still subject to commands

set for them in the configuration file). Both

<command>install</command> and <command>remove</command> commands
|

will currently be ignored when this option is used regardless of

other (and not both) of <option>--ignore-install</option> or

<option>--ignore-remove</option>. See <citerefentry>

This option does everything but actually insert or delete the

modules (or run the install or remove commands). Combined with

<option>-v</option>, it is useful for debugging problems. For
|
|
historical reasons both <option>--dry-run</option> and
|
|
<option>--show</option> actually mean the same thing and are
|
|
interchangeable.

With this flag, <command>modprobe</command> won't print an error

message if you try to remove or insert a module it can't find (and

|
isn't an alias or
|
|
<command>install</command>/<command>remove</command> command).
|
|
However, it will still return with a non-zero exit status. The
|
|
kernel uses this to opportunistically probe for modules which might
|
|
exist using request_module.

This option causes <command>modprobe</command> to remove rather
|
|
than insert a module. If the modules it depends on are also
|
|
unused, <command>modprobe</command> will try to remove them too.
|
|
Unlike insertion, more than one module can be specified on the
|
|
command line (it does not make sense to specify module parameters
|
|
when removing modules).
|

</para>
|

<para>
|

There is usually no reason to remove modules, but some buggy

|
modules require it. Your distribution kernel may not have been

built to support removal of modules at all.

List the dependencies of a module (or alias), including the module

one per line, each starting with "insmod" and is typically used by

distributions to determine which modules to include when generating

initrd/initramfs images. <command>Install</command> commands which

apply are shown prefixed by "install". It does not run any of the

install commands. Note that

<citerefentry><refentrytitle>modinfo</refentrytitle><manvolnum>8</manvolnum></citerefentry>

can be used to extract dependencies of a module from the module
