8.45. Kmod-27

The Kmod package contains libraries and utilities for loading kernel modules

Approximate build time: 0.1 SBU
Required disk space: 13 MB

8.45.1. Installation of Kmod

Prepare Kmod for compilation:

./configure --prefix=/usr          \
            --bindir=/bin          \
            --sysconfdir=/etc      \
            --with-rootlibdir=/lib \
            --with-xz              \

The meaning of the configure options:

--with-xz, --with-zlib

These options enable Kmod to handle compressed kernel modules.


This option ensures different library related files are placed in the correct directories.

Compile the package:


This package does not come with a test suite that can be run in the LFS chroot environment. At a minimum the git program is required and several tests will not run outside of a git repository.

Install the package and create symlinks for compatibility with Module-Init-Tools (the package that previously handled Linux kernel modules):

make install

for target in depmod insmod lsmod modinfo modprobe rmmod; do
  ln -sfv ../bin/kmod /sbin/$target

ln -sfv kmod /bin/lsmod

Short Descriptions


Creates a dependency file based on the symbols it finds in the existing set of modules; this dependency file is used by modprobe to automatically load the required modules


Installs a loadable module in the running kernel


Loads and unloads kernel modules


Lists currently loaded modules


Examines an object file associated with a kernel module and displays any information that it can glean


Uses a dependency file, created by depmod, to automatically load relevant modules


Unloads modules from the running kernel


This library is used by other programs to load and unload kernel modules
