Note that wireguard has been merged into the mainline kernel, so on newer (21.05+) versions of NixOS with the default kernel wireguard is no longer an option available. | Note that wireguard has been merged into the mainline kernel, so on newer (21.05+) versions of NixOS with the default kernel wireguard is no longer an option available. | ||

The config attribute <code>boot.kernelParams</code> can be set to supply the Linux kernel with additional command line arguments at boot time. | You can use <code>boot.extraModprobeConfig</code>, which is analogous to creating modprobe.conf files in /etc/modprobe.d/ in regular Linux distributions. This can be used for both built-in and loadable kernel modules. | ||
