Oh man…
I’m still using Void and I love it! It offers a base system, in a way kind of more basic than NetBSD. On Void you have to install Xorg, it’s not there to start with. Actually, you can even install xorg-minimal and add only the drives you need for your hardware. Yeah, I know I can compile a custom kernel on NetBSD as well.
Also, Void has builds for musl-libC (that’s what I have installed), not only GlibC.
Void was originally developed by a NetBSD dev, so in a sense they are related. The package manager xbps is similar to pkgin, but you also have xbps-src which is similar to pkgsrc.
I could go on forever… but, Void is the closest you can get to BSD on linux. They even ported doas as a replacement for sudo 😃
