### BUILD OPTIONS
# You can modify these settings by executing "env _<setting>=<value> makepkg"
# instead of modifying the PKGBUILD file. Here's an example:
2024-10-29 19:40:00 +01:00
# 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.

: "${_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.
