#! /bin/sh # # This script is used to configure the linux kernel. # # It was inspired by a desire to not have to hit 9 million times # or startup the X server just to change a single kernel parameter. # # This script attempts to parse the configuration files, which are # scattered throughout the kernel source tree, and creates a temporary # set of mini scripts which are in turn used to create nested menus and # radiolists. # # It uses a very modified/mutilated version of the "dialog" utility # written by Savio Lam (lam836@cs.cuhk.hk). Savio is not responsible # for this script or the version of dialog used by this script. # Please do not contact him with questions. The official version of # dialog is available at sunsite.unc.edu or a sunsite mirror. # # Portions of this script were borrowed from the original Configure # script. # # William Roadcap was the original author of Menuconfig. # Michael Elizabeth Chastain (mec@shout.net) is the current maintainer. # # 070497 Bernhard Kaindl (bkaindl@netway.at) - get default values for # new bool, tristate and dep_tristate parameters from the defconfig file. # new configuration parameters are marked with '(NEW)' as in make config. # # 180697 Bernhard Kaindl (bkaindl@netway.at) - added the needed support # for string options. They are handled like the int and hex options. # # 081297 Pavel Machek (pavel@atrey.karlin.mff.cuni.cz) - better error # handling # # 131197 Michael Chastain (mec@shout.net) - output all lines for a # choice list, not just the selected one. This makes the output # the same as Configure output, which is important for smart config # dependencies. # # 101297 Michael Chastain (mec@shout.net) - remove sound driver cruft. # # 221297 Michael Chastain (mec@shout.net) - make define_bool actually # define its arguments so that later tests on them work right. # # 160198 Michael Chastain (mec@shout.net) - fix bug with 'c' command # (complement existing value) when used on virgin uninitialized variables. # # 090398 Axel Boldt (boldt@math.ucsb.edu) - allow for empty lines in help # texts. # # 12 Dec 1998, Michael Elizabeth Chastain (mec@shout.net) # Remove a /tmp security hole in get_def (also makes it faster). # Give uninitialized variables canonical values rather than null value. # Change a lot of places to call set_x_info uniformly. # Take out message about preparing version (old sound driver cruft). # # 13 Dec 1998, Riley H Williams # When an error occurs, actually display the error message as well as # our comments thereon. # # 31 Dec 1998, Michael Elizabeth Chastain (mec@shout.net) # Fix mod_bool to honor $CONFIG_MODULES. # Fix dep_tristate to call define_bool when dependency is "n". # # 02 January 1999, Michael Elizabeth Chastain (mec@shout.net) # Blow away lxdialog.scrltmp on entry to activate_menu.
