depmod.d - Configuration 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 kernel.
The format of 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
files 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
using this built-in search string: "updates built-in"
but more complex arrangements are possible and are used in several popular
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.
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
by specifying the following command: "override kmod *
extra". This will ensure that any matching module name installed under
subdirectory within /lib/modules (or other module location)
will take priority over any likenamed module already provided by the
