Yeah, iirc it was a former NetBSD developer who made Void.

Alpine still honestly feels more BSDish in some ways than Void to me. Probably has to do with Alpine's install scripts being similar to OpenBSD's.

I'll be honest, I've learned the hard way that there really isn't any 1:1 BSD experience on Linux. Some may have similar packaging systems, but the base system depends on packages on Linux-based OSes. A shame because my favorite thing about BSDs is that packages are optional.

That being said, I do think the most BSD-like experience with the Linux kernel is going to be Chimera Linux, which was, funnily enough, created by a former Void developer.
