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 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

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

       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.
