It's not as well known as FreeBSD (or Linux) but yet you've got everything in a smaller community that's well organized and big enough that you can, share, and learn with them. I like that pace :)
I hope I will be able to offer minimal contributions to the kernel: for now, my project is adding an init_flag to pass the kernel to be loaded,and the init run too, like --init-args do similar on FreeBSD or Linux,
My other project is about boot time metrics: https://old.reddit.com/r/NetBSD/comments/1agmfja/collecting_... My other small project is for metering boot: I'ts just small sqlite database that'll automatically extract tslog boot info to better track regressions, improvements etc: with a kernel that now boots in 60 ms or less, you want very accurate numbers!
