DEPMOD.CONF(5)                                                                                                    DEPMOD.CONF(5)



NAME
       depmod.conf, depmod.d - Configuration file/directory for depmod

DESCRIPTION
       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 depmod.conf and 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 file a bit neater.

COMMANDS
       path subdirectory...
              This  allows  you to specify additional directories (other than the default of /lib/modules) that will be searched
              and indexed for available modules by depmod. This option can be used in combination with the search option  (which
              configures behavior within a given directory specified using the path option).

              By  default,  depmod will search the standard system /lib/modules/kernelversion directory for modules, but you can
              use this option to have it index additional directories that may be on an entirely different filesystem.

       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.

              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  distribu-
              tions.

       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 kmp by specifying  the  fol-
              lowing  command: "override kmp * 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.
