# Patch and Build Options
###########################################################################################################
#
## Note all kernels get the ck patch set with BFS so there is no option to enable/disable it!
#
_usearchlogo="y" # use the blue Arch logo rather than default tux logo when booting
_makenconfig="y" # select additional kernel options prior to a build via nconfig
_localmodcfg="n" # compile ONLY probed modules - see notes below!
_localyescfg="n" # convert all modules to core - see notes below!
_use_current="n" # use the current kernel's .config file - see notes below!
_use_my_config="y" # use my config file instead of download. myconfig will be used
_BFQ_enable_="y" # enable BFQ as the default I/O scheduler

# More Details and References
###########################################################################################################
## LOCALMODCONFIG OPTION
# As of mainline 2.6.32, running with this option will only build the modules that you currently have
# probed in your system VASTLY reducing the number of modules built and the build time to do it.
#
# WARNING - make CERTAIN that all modules are modprobed BEFORE you begin making the pkg!
# Read, https://bbs.archlinux.org/viewtopic.php?pid=830221#p830221
# To keep track of which modules are needed for your specific system/hardware, give my module_db script
# a try: http://aur.archlinux.org/packages.php?ID=41689
#
# Note that if you use my script, this PKGBUILD will auto run the reload_data base for you to probe
# all the modules you have logged!
#
## LOCALYESCONFIG OPTION
# This adds the option localyesconfig to make. This is similar to localmodconfig, but after it removes
# unnecessary modules it runs "sed -i s/=m/=y/" on the .config file. It then runs "make silentoldconfig"
# to fix any holes that were created by the conversion of modules to core.
## USE CURRENT KERNEL'S .CONFIG
# Enabling this option will use the .config of the RUNNING kernel rather than the ARCH defaults.
# Useful when the package gets updated and you already went through the trouble of customizing your
# config options. NOT recommended when a new kernel is released, but again, convenient for package bumps.
## BFQ
# Alternative I/O scheduler by Paolo. For more, see: http://algo.ing.unimo.it/people/paolo/disk_sched/
