Although as mentioned in the article, this won't work on systems like *BSD, Solaris or macOS.

> And while it is likely that dhclient will eventually be removed from OpenBSD Base, it will live on in Ports, where it will be available to those who desire to use it:
To be clear, OpenBSD's dhclient is not ISC dhcp client, it is a version that has been maintained in OpenBSD for many years and has a weaker form of privsep, but dhcpleased is a new daemon written to be more in-line with other OpenBSD daemons.

It definitely should not have been, this is news related to OpenBSD, there are no portable versions of either daemon.

I don't buy this. Some Acer laptops in the past have required that you set a Supervisor BIOS password in order to change the Secure Boot settings, but after you do that you can set the password to blank to clear it again.

It's looking very much like it will, but even if that wasn't the case, it's already widely in use and available in OS libc's and easy to copy, and it has been since OpenBSD first introduced it over 20 years ago. I also believe your performance claims are exaggerated.. and strlcpy does exactly what people want and expect in most scenarios.

> strlcpy... it’s not standard so it doesn’t satisfy 5 either.
It's a de facto standard supported on *BSD/macOS/Android/Linux(w/ musl libc) and a number of other commercial systems, it's also on track for standardization in POSIX (Issue 8).

While it might not meet your arbitrary set of requirements, it already has decent adoption.

I unfortunately skimmed over this, isotopp's explanation helped clear things up in my head.

Thanks for this part, I feel like this was a crucial piece of information I was missing. Also explains my observations about TRIM not being as important as people claim it is, the firmware on modern flash storage seems more than capable of handling this without OS intervention.

> Because flash does not overwrite anything, ever.
This is repeated multiple times in the article, and I refuse to believe it is true. If NVME/SSDs never overwrote anything, they would quickly run out of available blocks, especially on OSs that don't support TRIM.

This is HN, I'm sure people would appreciate hearing the details. Like how does this integrate with OpenBSD's existing audio/graphics stacks, do you plan to upstream your work? With it being OpenBSD, are there security implications?

> I modified the OpenBSD kernel for the raspberry pi with gaming related extensions, in such a way that when the game runs there is no latency and no stuttering.
What does that even mean? What "gaming related extensions"?-- could you elaborate?
OpenBSD doesn't have any accelerated drivers for the GPU on the RPi, so I'm curious what your "no latency/no stuttering" modifications would even be, beyond perhaps maybe recompiling the kernel with HZ=1000 or something else..

> "OpenBSD users: Hi Mark!"
This is Mark Kettenis, who has despite comments made jokingly by marcan, been working with a few other OpenBSD developers to bring-up OpenBSD/arm64 on the Apple M1. At least on the Mac Mini the Gigabit Ethernet works, Broadcom Wi-Fi, and work on the internal NVMe storage is progressing.
There was an early teaser dmesg posted in Feburary showing OpenBSD booting multi-user (on bare metal): https://marc.info/?l=openbsd-arm&m=161386122115249&w=2
Mark has also been adding support for the M1 to the U-Boot project, which will not only benefit OpenBSD, but also Asahi Linux.
Another OpenBSD developer posted these screenshots and videos on Twitter.

Why wouldn't it be true? It's not as if the source and images aren't available for you to look at for yourself.
As for why BSD isn't more popular than Linux, well, that's a much bigger question. It could come down to licensing, project goals (not winning popularity contests), but mostly decades of history and Linux appearing at the right place, at the right time. There is place for alternative operating systems, choice is important.
