# If the .config file isn't up to date with the chosen kernel version, any extra CONFIG_XXXX is set to its default value.
# Note: the script copies the resulting .config file as "kernelconfig.new" next to the PKGBUILD as a convenience for an eventual re-use. It gets overwritten at each run.
# One can use "kernelconfig.new" here to always use the latest edited .config file. modprobed-db needs to be used only once for its changes to be picked up.
