kmod - Linux kernel module handling
OVERVIEW
kmod is a set of tools to handle common tasks with Linux kernel modules like insert, remove, list, check properties, resolve dependencies and aliases.
These tools are designed on top of libkmod, a library that is shipped with kmod. See libkmod/README for more details on this library and how to use it. The aim is to be compatible with tools, configurations and indexes from module-init-tools project.

Compilation and installation
In order to compile the source code you need the following software packages:
- GCC/CLANG compiler
- GNU C library / musl / uClibc
Optional dependencies, required with the default build configuration:
- ZLIB library
- LZMA library
- ZSTD library
- OPENSSL library (signature handling in modinfo)
Typical configuration and installation
meson setup builddir/
meson compile -C builddir/
sudo meson install -C builddir/
For end-user and distributions builds, it's recommended to use:
meson setup --buildtype release builddir/
Alternatively you can try autotools build. NOTE: The autotools build is slated for removal with kmod v35
./configure CFLAGS="-g -O2" --prefix=/usr \
--sysconfdir=/etc --libdir=/usr/lib
make && make install
Hacking
When working on kmod, use the included build-dev.ini file, as:
meson setup --native-file build-dev.ini builddir/
Make sure to read our contributing guide and the other READMEs: libkmod and testsuite.
Compatibility with module-init-tools
kmod replaced module-init-tools, which was EOL'ed in 2011. All the tools were rewritten on top of libkmod and they can be used as drop in replacements. Along the years there were a few behavior changes and new features implemented, following feedback from Linux kernel community and distros.
