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 pro-
       cessing in order to override the module version supplied by the kernel.

       The format of depmod.conf and files under depmod.d is simple: one  com-
       mand per line, with blank lines and lines starting with # ignored (use-
       ful for adding comments).  A \ at the end of a line causes it  to  con-
       tinue on the next line, which makes the file a bit neater.

COMMANDS

       search subdirectory...
              This  allows  you to specify the order in which /lib/modules (or
              other configured module location) subdirectories  will  be  pro-
              cessed  by  depmod.  Directories  are  listed in order, with the
              highest priority given to the first  listed  directory  and  the
              lowest  to  the last. 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 spec-
              ify one kernel or all kernels using the * wildcard.   modulesub-
              directory 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 following com-
              mand: "override kmp * extra".  This will ensure that any  match-
              ing  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.

       include filename
              Using  this  command, you can include other configuration files,
              or whole directories, which is occasionally useful.
