kloadsrv(8)
NAME
  kloadsrv - Invokes the kernel load server daemon

SYNOPSIS
  /sbin/kloadsrv [-V] [-f] [-d debug_level] [-k] [-log logfile] [-q] [-s
  kernel_symtab_file] [kernel_object_filename]

  /sbin/kloadsrv [-w kernel_symtab_file] kernel_object_filename

OPTIONS
  -V  Displays the version of the kloadsrv command.

  -f  Causes the kloadsrv daemon to remain in the foreground. By default, the
      daemon automatically places itself into the background after it
      initializes.

  -d debug_level
      Specifies the level of debugging information. The debug_level is a
      small integer. A value of zero (0) disables debugging. Nonzero values
      from 1 to higher levels cause kloadsrv to display various log messages.

  -k  Kills the kloadsrv daemon, if it is running.

  -log logfile
      Specifies that the debugging information is to be sent to the specified
      log file. The logfilevariable must be specified as a full pathname. By
      default, the debugging information is sent to the console device,
      /dev/console.

  -q  Queries and prints the process id of the kloadsrv daemon, if it is
      running, or prints 0 otherwise.

  -s kernel_symtab_file
      Specifies the name of the kernel symbol table file. By default, the
      kernel symbol table file name is /vmunix.sym.

  -w kernel_symtab_file
      Specifies that the kloadsrv command write a kernel symbol table file
      and then exit. When you specify the -w option, you must also specify a
      kernel_object_filename.

DESCRIPTION
  This command invokes the kloadsrv daemon, which loads kernel modules into
  the kernel. Command options in the first line of the synopsis are valid
  when you invoke kloadsrv automatically during system startup. The kloadsrv
  daemon typically starts during system startup as specified in the
  /etc/inittab file. Options in the second line of the command synopsis are
  valid when you invoke kloadsrv manually from the command line.

  In the first invocation form, the kernel_object_filename variable is the
  pathname of the file from which the running kernel was booted. In the
  second invocation form, the kernel_object_filename variable is not
  optional. You must specify a value, which is the path to any linked kernel
  image for which you want to generate a kernel symbol table file.

  If you omit an argument for kernel_object_filename from the startup command
  line, the kloadsrv daemon uses the running kernel.

  Usually, you must specify an argument for kernel_object_filename only if
  you moved the booted kernel image after the kernel was booted. This is
  required because the kloadsrv daemon uses the value returned by the
  following command:

       /usr/sbin/sizer -b

  The sizer command returns the default kernel object file name.

  For example, suppose you move the running kernel as follows:

       /sbin/mv /vmunix /vmunix.bak
       /sbin/mv /genvmunix /vmunix

  If you then need to restart the kloadsrv daemon, you must invoke it as
  follows:

       /sbin/kloadsrv /vmunix.bak

  When moving the booted kernel, you should take great care. During its
  initialization, the kloadsrv daemon builds a list of kernel symbols used by
  device drivers. Moving or overwriting the kernel object file while in
  single user mode, can cause the addresses in this list of symbols to be
  inaccurate. The addresses in the list reflect the addresses in the new
  kernel, not the addresses in the booted kernel. This will cause problems if
  you then transition the system to multiuser mode.

  If the kernel object file does not exist, the kloadsrv daemon reads its
  symbol information from the file named /vmunix.sym which is the default
  pathname for the kernel symbol table. You can specify an alternate path to
  the kernel symbol table file by using the -s option.

  When the kloadsrv daemon initializes itself, it puts itself into the
  background and enters its server loop, where it waits to receive and
  respond to load requests, unload requests, and query requests. If you
  specify the -f option, the daemon remains in the foreground.

  You can invoke the kloadsrv daemon using the -w option to create a kernel
  symbol table file. You can then specify this symbol table file as an
  argument to the -s option, or copy the file to /vmunix.sym and use it as
  the default kernel symbol table file.

  When the kloadsrv daemon is invoked with the -w option  it runs in the
  foreground and never enters its server loop.	After writing the symbol
  table file, the daemon exits without performing any server functions.
