   8 _use_current="n"        # use the current kernel's .config file
   9 _BFQ_enable_="n"        # enable BFQ as the default I/O scheduler

  11 ### DOCS
  12 # DETAILS FOR _localmodcfg="y"
  13 # As of mainline 2.6.32, running with this option will only build the modules that you currently have
  14 # probed in your system VASTLY reducing the number of modules built and the build time to do it.
  15 #
  16 # WARNING - make CERTAIN that all modules are modprobed BEFORE you begin making the pkg!
  17 #
  18 # To keep track of which modules are needed for your specific system/hardware, give my module_db script
  19 # a try: http://aur.archlinux.org/packages.php?ID=41689  Note that if you use my script, this PKGBUILD
  20 # will auto run the 'sudo modprobed_db reload' for you to probe all the modules you have logged!
  21 #
  22 # More at this wiki page ---> https://wiki.archlinux.org/index.php/Modprobed_db
  23
  24 # DETAILS FOR _use_current="y"
  25 # Enabling this option will use the .config of the RUNNING kernel rather than the ARCH defaults.
  26 # Useful when the package gets updated and you already went through the trouble of customizing your
  27 # config options.  NOT recommended when a new kernel is released, but again, convenient for package bumps.

  29 # DETAILS FOR _BFQ_enable="y"
