Some #NetBSD questions that keep coming up.
We don't use modules for HW drivers in the default install. All baked into the kernel. If you're curious about desktop hardware, for x86 there are lists https://wiki.netbsd.org/laptops/ https://wiki.netbsd.org/gpus/ (and the pci/usb manual pages)
x86 virtual machines. https://www.netbsd.org/docs/guide/en/chap-virt.html#chap-virt-guest
For disk encryption there's different options, such as creating a small root with the installer, then adding encrypted partitions later (see man cgdconfig). Also: cgdroot.
Running commercial games? It is possible, but you'll probably have better luck with DRM-free indie games. https://washbear.neocities.org/valhalla
No audio output? It is possible your default device or output DAC needs to be changed, see the instructions on https://www.netbsd.org/docs/guide/en/chap-audio.html
WireGuard® VPNs? See the EXAMPLES section of https://man.netbsd.org/wg.4
ZFS? Yes, we are using it in production. No, it isn't the same branch as Linux or FreeBSD.
