4. LKM Utilities
The programs you need to load and unload and otherwise work with LKMs
are in the package modutils. You can find
this package in
This package contains the following programs to help you use LKMs:
Insert an LKM into the kernel.
Remove an LKM from the kernel.
Determine interdependencies between LKMs.
Kerneld daemon program
Display symbols that are exported by the kernel for
use by new LKMs.
List currently loaded LKMs.
Display contents of .modinfo section in an
LKM object file.
Insert or remove an LKM or set
of LKMs intelligently. For example, if you must load A before
loading B, Modprobe will automatically load A when you tell it
to load B.
Changes to the kernel often require changes to
modutils, so be sure you're using a current
version of modutils whenever you upgrade
your kernel. modutils is always backward
compatible (it works with older kernels), so there's no such thing as
having too new a modutils.
Warning: modprobe invokes insmod
and has its location hardcoded as /sbin/insmod.
There may be other instances in modutils of
the PATH not being used to find programs. So either modify the source
code of modutils before you build it, or
make sure you install the programs in their conventional directories.
