Here's an example: # env _makemenuconfig=y _copyfinalconfig=y _subarch=30 makepkg # Tweak kernel options prior to a build via menuconfig. # # Set to anything but null to activate. : "${_makemenuconfig:=""}" # Tweak kernel options prior to a build via nconfig. # # Set to anything but null to activate. : "${_makenconfig:=""}" # Tweak kernel options prior to a build via xconfig. # # Set to anything but null to activate. : "${_makexconfig:=""}" # Use the current kernel's .config file # Enabling this option will use the .config of the currently # running kernel rather than the Arch Linux defaults. Useful # when the package gets updated and you already went through # the trouble of customizing your config options. NOT recommended # when a new kernel is released, but again, convenient # for package bumps. # # Set to anything but null to activate. : "${_use_current:=""}" # Determines whether the kernel configuration should be # copied into the source tree before compilation starts. # # Set to anything but null to activate. : "${_copyfinalconfig:=""}" # Only compile active modules to VASTLY reduce the number # of modules built and the build time. # # To keep track of which modules are needed for your specific system/hardware, # give modprobed-db a try: https://aur.archlinux.org/packages/modprobed-db # # More at this wiki page ---> https://wiki.archlinux.org/index.php/Modprobed-db # Set to anything but null to activate. : "${_localmodcfg:=""}" # Optionally select a sub architecture by number or # leave blank, which will require user interaction during the build. # Note that the default option is 41. # # 1.
