DESCRIPTION
       is  the administrative command for HP-UX kernel configurations.	In the
       first form, will give summary information about the  currently  running
       kernel  configuration.  In the second form, will give information about
       saved kernel configurations.  If configuration names are listed on  the
       command line, the output is restricted to those configurations.	In the
       other forms, supports various administrative tasks on kernel configura‐
       tions.	See  kconfig(5)	 for  more information about kernel configura‐
       tions.

       Only users with appropriate privileges can specify the or options.

   Options
       Includes detailed information about each kernel configuration in the
		      output listing (see below).  In addition,	 the  informa‐
		      tion  about  each	 configuration will be followed by the
		      outputs of:

		      for the configuration, so as to include  all  configura‐
		      tion  data.   Note: if additional configuration data are
		      available in future releases  of	HP-UX,	they  will  be
		      included as well.

       Specifies whether or not to update the automatic backup
		      configuration  before the requested change.  Also speci‐
		      fies the default backup  behavior	 for  future  changes.
		      See  kconfig(5)  for a description of the various backup
		      behaviors.

		      For compatibility with old releases, is accepted	as  an
		      alias  for and is accepted as an alias for These aliases
		      will be removed in a future release.

       will make a copy of the saved kernel configuration named
		      src.  The copy  will  be	named  dest.   dest  must  not
		      already exist.

       The specified  comment will be included in the kernel configuration log
		      file entry made for this invocation of For more  details
		      on  the  kernel  configuration  log file, see kclog(1M).
		      Note that it will usually be necessary to quote the com‐
		      ment in order to avoid interpretation by the shell.

       will delete the saved kernel configuration named
		      config,  and  any	 files associated with it.  Some files
		      are shared between saved configurations; these files are
		      not  deleted until all of the saved configurations using
		      them have been deleted.

       will display all changes to the current kernel configuration that are
		      being held for next boot.	 In other words, it will  exe‐
		      cute:

		      If  any  additional  kernel  configuration  data	become
		      available in future HP-UX releases, changes to them will
		      be  included  as well.  The return value of will be 1 if
		      there are any such changes; see the section below.   Not
		      valid in combination with any other flags.

       will export the saved kernel configuration named
		      config  to  a  system file named filename, replacing the
		      file if it already exists.  If no config	is  specified,
		      the  currently  running  kernel  configuration  will  be
		      exported, including any changes to  it  that  are	 being
		      held  for	 next  boot.   The  exported file can be later
		      imported using on this system or any other  system  with
		      compatible HP-UX software.  See kconfig(5) and system(4)
		      for more information about system files.

       Tells	      to proceed with  the  requested  operation  despite  its
		      potentially  dangerous  nature.  When is asked to make a
		      change that could result in  unintended  data  loss,  it
		      will ask for confirmation if being run interactively, or
		      print an error message and stop otherwise.   The	change
		      can  be made, and the interactive confirmation bypassed,
		      by running the command with the option.

       Tells	      to hold the requested changes until the next boot,  even
		      if they could be applied immediately.

       Discards all changes being held pending for next boot. The currently
		      running configuration will be used at next boot.

       will import a kernel configuration from the system file named
		      filename,	 which	may have been created by an invocation
		      of (on any system).  If config is specified, the result‐
		      ing  kernel configuration will be saved under that name.
		      Otherwise, the resulting kernel  configuration  will  be
		      applied to the currently running system, overwriting any
		      changes that were being held for	next  boot.   The  new
		      configuration  changes  will  be held until next boot if
		      they cannot be applied immediately, or if the option  is
		      specified.

		      When  duplicate entries for particular tunable or module
		      are found in the system file, only the last entry	 found
		      is used.

		      A	 kernel	 configuration cannot be imported successfully
		      unless the running system has all of the necessary  ker‐
		      nel  software  installed.	  If  the  importing system is
		      missing kernel software components that were in  use  on
		      the  exporting  system,  the  import will fail.  See the
		      option below.

       Enables and disables saving of system files as
		      and

		      is a copy of system file from which the  machine	boots.
		      When the feature is switched ON for the first time, is a
		      copy of the system file at that point.  is the  copy  of
		      the  system  file from which the machine was booted last
		      time.  These files are created in will save the  current
		      system  file  as	and  will  keep	 updating  it on every
		      reboot.  It will also create a file which contains noth‐
		      ing on first invocation.

		      will  remove  these files from the machine and will dis‐
		      able this feature.

       will load the saved kernel configuration named
		      config, overwriting any changes that were being held for
		      next  boot.   The	 state of the currently running system
		      will be changed to match the  saved  configuration.   If
		      the  changes  cannot  be	applied without a reboot, they
		      will be marked to take effect at next boot.

       The saved kernel configuration named
		      config will be marked for use at next boot.  Any changes
		      to  the  currently  running configuration that are being
		      held for next boot are discarded.

       Tells	      to include only the specified fields in its output,  and
		      to  print them in the machine-readable form described in
		      kconfig(5).  See the below.  Not	valid  in  combination
		      with

       The saved kernel configuration named
		      old  will be renamed new.	 The name new must not already
		      be in use.

       will save the running kernel configuration under the name
		      config.

       will display all settings of the currently running configuration
		      that are not at their default value.  In other words, it
		      will execute:

		      If  any  additional  kernel  configuration  data	become
		      available in future HP-UX	 releases,  settings  of  them
		      will be included as well.	 Not valid in combination with
		      any other flags.

       will change the title of the saved kernel configuration named
		      config to the given title.  title will usually  need  to
		      be quoted to avoid interpretation by the shell.

       Includes verbose information about each saved kernel configuration in
		      the  output  listing.  The information includes the name
		      and title of the	configuration,	the  pathname  of  the
		      associated kernel, the creation date and time, etc.

       Requests	 strict	 version checking.  With this option, an import opera‐
       tion
		      will only succeed if the kernel components installed  on
		      the  importing  system  are  the	exact same versions as
		      those installed on the exporting system.

       Prints information about the original source of the currently running
		      configuration.  Specifically, it describes the source of
		      the  most recent complete kernel configuration operation
		      (load, boot, or import).	Also, if a saved configuration
		      is  marked  for use at next boot, this option will iden‐
		      tify it.

		      Note that this source information does  not  imply  that
		      the currently running configuration matches its original
		      source.  may say that the currently  running  configura‐
		      tion  was	 loaded	 from the saved configuration but that
		      does not mean that the two are  identical.   Either  one
		      may have been changed since the load occurred.

   Developer's Note
       The layout and content of output may change without notice, except when
       is specified.  Scripts or applications that need to parse the output of
       are expected to use the option.	See kconfig(5) for details.

       The fields supported in a request are:

	      The name of the saved kernel configuration.

	      The title for the saved kernel configuration.  If the
			       configuration does not have a title, this field
			       will be empty.

	      The date and time of the last save
			       of the configuration, in the format returned by

	      The date and time when the configuration	was  created,  in  the
	      format returned by

	      The  username  of	 the  user  who	 created the configuration, if
	      available.

	      The date and time of the last change to the saved configuration,
	      in
			       the format returned by

	      The  username  of the user who made the last change to the saved
	      configuration,
			       if available.

	      The pathname of the corresponding kernel directory.

       The special field name may be specified to indicate  that  all  defined
       fields should be included in the output.	 The output may include fields
       not listed in this man page.  The fields will be listed in  unspecified
       order.

       Additional fields may be added in future releases or in patches.

RETURN VALUE
       returns one of the following values:

       The requested operation was successful.	If
	    was	 specified, this return value indicates that there are no con‐
	    figuration changes being held for next boot.

       The  requested  operation  could	 not  be  performed   immediately   as
       requested,
	    and	 is being held pending until the next boot.  If was specified,
	    this return value indicates that there are	configuration  changes
	    being held for next boot.

       The requested operation failed.	A diagnostic message is printed.
