DEPMOD.D(5)                      depmod.d                     DEPMOD.D(5)

NAME         top

       depmod.d - Configuration directory for depmod

SYNOPSIS         top

       /etc/depmod.d/*.conf

       /run/depmod.d/*.conf

       /usr/local/lib/depmod.d/*.conf

       /usr/lib/depmod.d/*.conf

       /lib/depmod.d/*.conf

DESCRIPTION         top

       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         top

       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         top

       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).

COMMANDS         top

       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.
