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


       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 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.


       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 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
