NAME

       kernel-img.conf - site wide configuration file for kernel image packages

SYNOPSIS

       /etc/kernel-img.conf

DESCRIPTION

       The  file  /etc/kernel-img.conf  is  a  simple  file  looked  at  by the kernel image post
       installation process to allow local options for handling some aspects of the installation,
       overriding the defaults built into the image itself.

       The  format  of  the file is a simple VAR = VALUE pair. Boolean values may be specified as
       Yes, True, 1, and No, False, 0, and are case  insensitive.   This  file  is  automatically
       created by the installation script in certain circumstances.

       At the moment, the user modifiable variables supported are:

       postinst_hook
              DEPRECATED:  Set  this variable to a script to be executed during installation. The
              path can be a relative path if the script lives in a safe path -- that  is,  if  it
              lives  in /bin, /sbin, /usr/bin, or /usr/sbin, or must be an absolute path instead.
              Before calling this script, the env variable STEM shall be set to the value of  the
              --stem  argument (or the default value, linux), and KERNEL_PACKAGE_VERSION shall be
              set to the version of the kernel-package that created  the  package.   This  script
              shall  be  called  with  two  arguments,  the first being the version of the kernel
              image, and the second argument being the  location  of  the  kernel  image  itself.
              Errors  in  the  script  shall  cause the postinst to fail. Since debconf is in use
              before the script is called, this script should issue  no  diagnostic  messages  to
              stdout  --  while the postinst does call db_stop , debconf does not restore stdout,
              so messages to stdout disappear.  An example script for grub users  is  present  in
              /usr/share/doc/kernel-package/  directory.  This script is run after the scripts in
              /etc/kernel/postinst.d directory.

       postrm_hook
              DEPRECATED: Set this variable to a script to be executed in the  postrm  (that  is,
              after the image has been removed) after all the remove actions have been performed.
              The path can be a relative path if the script lives in a safe path -- that  is,  if
              it  lives  in  /bin,  /sbin,  /usr/bin,  or  /usr/sbin, or must be an absolute path
              instead. The environment  variable  KERNEL_PACKAGE_VERSION  shall  be  set  to  the
              version of the kernel-package that created the package. This script shall be called
              with two arguments, the first being the version of the kernel image, and the second
              argument  being the location of the kernel image itself. Errors in the script shall
              produce a warning message, but shall be otherwise ignored. Since debconf is in  use
              before  the  script  is  called, this script should issue no diagnostic messages to
              stdout --  while the postinst does call db_stop , debconf does not restore  stdout,
              so  messages  to  stdout  disappear.   This  script  is  run  after  the scripts in
              /etc/kernel/postrm.d directory.

       preinst_hook
              DEPRECATED: Set this variable to a script to be  executed  before  the  package  is
              unpacked,  and  can be used to put in additional checks. The path can be a relative
              path if the script lives in a safe path -- that is, if it  lives  in  /bin,  /sbin,
              /usr/bin,  or  /usr/sbin,  or  must  be  an  absolute path instead. The environment
              variable KERNEL_PACKAGE_VERSION shall be set to the version of  the  kernel-package
              that created the package. This script shall be called with two arguments, the first
              being the version of the kernel image, and the second argument being  the  location
              of   the   kernel   image  itself.   This  script  is  run  after  the  scripts  in
              /etc/kernel/preinst.d directory.

       prerm_hook
              DEPRECATED: Set this variable to a script to be executed before the  package  files
              are  removed  (so any added files may be removed) . The path can be a relative path
              if the script lives in a safe path  --  that  is,  if  it  lives  in  /bin,  /sbin,
              /usr/bin,  or  /usr/sbin,  or  must  be  an  absolute path instead. The environment
              variable KERNEL_PACKAGE_VERSION shall be set to the version of  the  kernel-package
              that created the package. This script shall be called with two arguments, the first
              being the version of the kernel image, and the second argument being  the  location
              of  the  kernel  image  itself. Errors in the script shall cause the prerm to fail.
              Since debconf is in use before the script is called, this script  should  issue  no
              diagnostic  messages  to  stdout  -- while the postinst does call db_stop , debconf
              does not restore stdout, so messages to stdout disappear.  This script is run after
              the scripts in /etc/kernel/prerm.d directory.

       src_postinst_hook
              DEPRECATED:  Unlike the other hook variables, this is meant for a script run during
              the post inst of a docs, headers or a source  package.  Using  this  hook  for  the
              headers  package  is  now  being deprecated, at some point the headers post install
              script shall only run the header_postinst_hook.  The path can be a relative path if
              the  script  lives in a safe path -- that is, if it lives in /bin, /sbin, /usr/bin,
              or /usr/sbin, or must  be  an  absolute  path  instead.  The  environment  variable
              KERNEL_PACKAGE_VERSION  shall  be  set  to  the  version of the kernel-package that
              created the package.  This script shall be called with  two  arguments,  the  first
              being  the name of the package being installed (could be kernel source or headers),
              and the second argument being the version of the package being installed. Errors in
              the  script shall cause the postinst to fail.  This script is run after the scripts
              in /etc/kernel/src_postinst.d directory.

       header_postinst_hook
              DEPRECATED: Unlike the other hook variables, this is meant for a script run  during
              the  post  inst  of  a headers package only. The path can be a relative path if the
              script lives in a safe path -- that is, if it lives in /bin,  /sbin,  /usr/bin,  or
              /usr/sbin,   or  must  be  an  absolute  path  instead.  The  environment  variable
              KERNEL_PACKAGE_VERSION shall be set to  the  version  of  the  kernel-package  that
              created  the  package.  This  script  shall be called with two arguments, the first
              being the name of the package being installed, and the second  argument  being  the
              version  of  the  package  being  installed.  Errors  in the script shall cause the
              postinst   to   fail.    This   script   is    run    after    the    scripts    in
              /etc/kernel/header_postinst.d directory.

       clobber_modules
              If  set, the preinst shall silently try to move /lib/modules/version out of the way
              if it is the same version as the image being installed. Use at your own risk.  This
              variable is unset by default.

       warn_reboot
              This  variable  can  be used to turn off the warning given when installing a kernel
              image which is the same version as the currently running version.  If  the  modules
              list  is  changed,  the modules dependencies may have been changed, and the modules
              for the new kernel may not run correctly on the running kernel if  the  kernel  ABI
              has  changed  in  the meanwhile. It is a good idea to reboot, and this is a note to
              remind you. If you know what you are doing, you can set this variable to  no.  This
              variable is set by default.

       relink_build_link
              This  option manipulates the build link created by recent kernels. If the link is a
              dangling link, and if a the  corresponding  kernel  headers  appear  to  have  been
              installed  on  the  system,  a  new  symlink shall be created to point to them. The
              default is to relink the build link (YES).

       force_build_link
              This option manipulates the build link created by recent kernels. If the link is  a
              dangling  link,  a  new symlink shall be created to point to kernel headers data in
              /usr/src, whether they have been installed or not. The default is unset,  we  don't
              create potentially dangling symlinks by default.

       relink_src_link
              This option manipulates the source link created by recent kernels. If the link is a
              dangling link it is deleted at install time. The default is to relink (delete)  the
              source link (YES).

       silent_modules
              This option has been put in for the people who are vastly irritated on being warned
              about preexisting modules directory /lib/modules/$version That directory may belong
              to  an  old  or defunct kernel image package, in which case problems may arise with
              leftover modules in that directory tree, or the directory  may  legitimately  exist
              due  to  a independent modules package being installed for this kernel version that
              has already been unpacked.  In this latter case the existence of the  directory  is
              benign.   If  you set this variable, you shall no longer be given a chance to abort
              if a preexisting modules directory  /lib/modules/$version  is  detected.   This  is
              unset be default.

       ignore_depmod_err
              If  set,  does  not  prompt  to  continue after a depmod problem in the postinstall
              script. This facilitates automated installs, though it may mask a problem with  the
              kernel image. A diagnostic is still issued. This is unset be default.
