DEPMOD.D(5) depmod.d DEPMOD.D(5)
depmod.d - Configuration directory for depmod
/etc/depmod.d/*.conf
/run/depmod.d/*.conf
/usr/local/lib/depmod.d/*.conf
/usr/local/lib/depmod.d/*.conf
/lib/depmod.d/*.conf
On execution depmod reads the configuration files from the above
location and based on that it processes the available modules and
their dependencies. For example: one can change the search order,
exclude folders, override specific module's location and more.
This is typically useful in cases where built-in kernel modules
are complemented by custom built versions of the same and the user
wishes to affect the priority of processing in order to override
the module version supplied by the kernel.
The configuration files contain one command per line, with blank
lines and lines starting with '#' ignored (useful for adding
comments). A '\' at the end of a line causes it to continue on the
next line, which makes the files a bit neater.
See the COMMANDS section below for more.
Configuration files are read from directories in listed in
SYNOPSIS in that order of precedence. Once a file of a given
filename is loaded, any file of the same name in subsequent
directories is ignored.
All configuration files are sorted in lexicographic order,
regardless of the directory they reside in. Configuration files
can either be completely replaced (by having a new configuration
file with the same name in a directory of higher priority) or
partially replaced (by having a configuration file that is ordered
later).
search subdirectory...
This allows you to specify the order in which /lib/modules (or
other configured module location) subdirectories will be
processed by depmod. Directories are listed in order, with the
highest priority given to the first listed directory and the
lowest priority given to the last directory listed. The
special keyword built-in refers to the standard module
directories installed by the kernel. Another special keyword
external refers to the list of external directories, defined
by the external command.
By default, depmod will give a higher priority to a directory
with the name updates using this built-in search string:
"updates built-in" but more complex arrangements are possible
and are used in several popular distributions.
override modulename kernelversion modulesubdirectory
This command allows you to override which version of a
specific module will be used when more than one module sharing
the same name is processed by the depmod command. It is
possible to specify one kernel or all kernels using the *
wildcard. modulesubdirectory is the name of the subdirectory
under /lib/modules (or other module location) where the target
module is installed.
For example, it is possible to override the priority of an
updated test module called kmod by specifying the following
command: "override kmod * extra". This will ensure that any
matching module name installed under the extra subdirectory
within /lib/modules (or other module location) will take
priority over any likenamed module already provided by the
kernel.
external kernelversion absolutemodulesdirectory...
This specifies a list of directories, which will be checked
according to the priorities in the search command. The order
matters also, the first directory has the higher priority.
The kernelversion is a POSIX regular expression or * wildcard,
like in the override.
exclude excludedir
This specifies the trailing directories that will be excluded
during the search for kernel modules.
The excludedir is the trailing directory to exclude.

Please direct any bug reports to kmod's issue tracker at
https://github.com/kmod-project/kmod/issues/ alongside with
version used, steps to reproduce the problem and the expected
outcome.
Numerous contributions have come from the linux-modules mailing
list <linux-modules@vger.kernel.org> and Github. If you have a
clone of kmod.git itself, the output of git-shortlog(1) and
git-blame(1) can show you the authors for specific parts of the
project.

maintainer of the project.
