NAME         top

       depmod.d - Configuration directory for depmod

SYNOPSIS         top




DESCRIPTION         top

       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 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.

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

           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.
