NAME
depmod.d - Configuration directory for depmod
SYNOPSIS
/etc/depmod.d/*.conf
/run/depmod.d/*.conf
/usr/local/lib/depmod.d/*.conf
/usr/lib/depmod.d/*.conf
/lib/depmod.d/*.conf
DESCRIPTION
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.
CONFIGURATION FORMAT
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 DIRECTORIES AND PRECEDENCE
Configuration files are read from directories in listed in SYNOPSYS 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).
COMMANDS
search subdirectory...
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
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...
The kernelversion is a POSIX regular expression or * wildcard, like in the override.
exclude excludedir
The excludedir is the trailing directory to exclude.
