  19. ## LOCALMODCONFIG OPTION
  20. # As of mainline 2.6.32, running with this option will only build the modules that you currently have
  21. # probed in your system VASTLY reducing the number of modules build.
  22. #
  23. # WARNING - make CERTAIN that all modules are modprobed BEFORE you begin making the pkg!
  24. # Read, https://bbs.archlinux.org/viewtopic.php?pid=830221#p830221
  25. # To keep track of which modules are needed for your specific system/hardware, give my module_db script
  26. # a try: http://aur.archlinux.org/packages.php?ID=41689
  27. #
  28. # Note that if you use my script, this PKGBUILD will auto run the reload_data base for you to probe
  29. # all the modules you have logged!
  30. #
  31. ## LOCALYESCONFIG OPTION
  32. # This adds the option localyesconfig to make. This is similar to localmodconfig, but after it removes
  33. # unnecessary modules it runs "sed -i s/=m/=y/" on the .config file. It then runs "make silentoldconfig"
  34. # to fix any holes that were created by the conversion of modules to core.
  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.
