  20 ## LOCALMODCONFIG OPTION
  21 # As of mainline 2.6.32, running with this option will only build the modules that you currently have
  22 # probed in your system VASTLY reducing the number of modules build.
  23 #
  24 # WARNING - make CERTAIN that all modules are modprobed BEFORE you begin making the pkg!
  25 # Read, https://bbs.archlinux.org/viewtopic.php?pid=830221#p830221
  26 # To keep track of which modules are needed for your specific system/hardware, give my module_db script
  27 # a try: http://aur.archlinux.org/packages.php?ID=41689
  28 #
  29 # Note that if you use my script, this PKGBUILD will auto run the reload_data base for you to probe
  30 # all the modules you have logged!
  31 #
  32 ## LOCALMODCONFIG OPTION
  33 # This adds the option localyesconfig to make. This is similar to localmodconfig, but after it removes
  34 # unnecessary modules it runs "sed -i s/=m/=y/" on the .config file. It then runs "make silentoldconfig"
  35 # to fix any holes that were created by the conversion of modules to core.
  36 ## USE CURRENT KERNEL'S .CONFIG
  37 # Enabling this option will use the .config of the RUNNING kernel rather than the ARCH defaults.
  38 # Useful when the package gets updated and you already went through the trouble of customizing your
  39 # config options.  NOT recommended when a new kernel is released, but again, convenient for package bumps.
