depmod.conf, depmod.d - Configuration file/directory for depmod
The order in which modules are processed by the depmod command can be
altered on a global or per-module basis. 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
The format of depmod.conf and files under depmod.d is simple: 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 file a bit neater.
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.
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
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
