  20. ## MAKENCONFIG OPTION
  21. # Allows you to select additional kernel options prior to a build via a nconfig.
  22. #
  23. ## LOCALMODCONFIG OPTION
  24. # As of mainline 2.6.32, running with this option will only build the modules that you currently have
  25. # probed in your system VASTLY reducing the number of modules build.
  26. #
  27. # WARNING - make CERTAIN that all modules are modprobed BEFORE you begin making the pkg!
  28. # Read, https://bbs.archlinux.org/viewtopic.php?pid=830221#p830221
  29. # To keep track of which modules are needed for your specific system/hardware, give my module_db script
  30. # a try: http://aur.archlinux.org/packages.php?ID=41689
  31. #
  32. # Note that if you use my script, this PKGBUILD will auto run the reload_data base for you to probe
  33. # all the modules you have logged!
  34. #
  35. ## USE CURRENT KERNEL'S .CONFIG
  36. # Enabling this option will use the .config of the RUNNING kernel rather than the ARCH defaults.
  37. # Useful when the package gets updated and you already went through the trouble of customizing your
  38. # config options. NOT recommended when a new kernel is released, but again, convenient for package bumps.
