   6 _makenconfig="n"        # tweak kernel options prior to a build via nconfig
   7 _localmodcfg="n"        # compile ONLY probed modules
   8 _use_current="n"        # use the current kernel's .config file
   9 #       Do NOT enable the BFQ patch - currently Paolo has not yet released a BFQ for the 3.2 tree!
  10 _BFQ_enable_="n"        # enable BFQ as the default I/O scheduler

  12 ### DOCS
  13 # DETAILS FOR _localmodcfg="y"
  14 # As of mainline 2.6.32, running with this option will only build the modules that you currently have
  15 # probed in your system VASTLY reducing the number of modules built and the build time to do it.
  16 #
  17 # WARNING - make CERTAIN that all modules are modprobed BEFORE you begin making the pkg!
  18 #
  19 # To keep track of which modules are needed for your specific system/hardware, give my module_db script
  20 # a try: http://aur.archlinux.org/packages.php?ID=41689  Note that if you use my script, this PKGBUILD
  21 # will auto run the reload_data base for you to probe all the modules you have logged!
  22 #
  23 # More at this wiki page ---> https://wiki.archlinux.org/index.php/Modprobed_db
  24
  25 # DETAILS FOR _use_current="y"
  26 # Enabling this option will use the .config of the RUNNING kernel rather than the ARCH defaults.
  27 # Useful when the package gets updated and you already went through the trouble of customizing your
  28 # config options.  NOT recommended when a new kernel is released, but again, convenient for package bumps.
  29
  30 # DETAILS FOR _BFQ_enable="y"
  31 # Alternative I/O scheduler by Paolo.  For more, see: http://algo.ing.unimo.it/people/paolo/disk_sched/
