From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Has anyone tried WSL on Windows ARM? (lemmy.world)

I know... I know.

But just out of curiosity about how it works. I remember back in some dark days of still dual booting getting curious about wsl1 and being fairly impressed. At the time I had a heavy gaming laptop and a Surface 3 I would take to class to keep my STEM student physic rather than going body builder moving an alienware around.

Having wsl was a neat tool to get started on some homework assignments before I got home to the real computer. Given that Windows ARM has been kind of a let down (or perhaps Apple just set too high a bar) I am curious about how this niche has turned out.

I always wonder how Docker works on macOS with a more UNIX-style kernel than Linux when even FreeBSD gave up on the effort.

I understand macOS is way closer to Linux than Windows (despite its differences) but is it really that hard to do Docker/OCI out of Linux?

It doesn't. Macos also uses a virtual machine for docker.

Yes. The runtimes containers use are dependent on cgroups, seccomp, namespaces, and a few other linux kernel specific features.

You could implement a wine like project to run the linux binaries that containers contain, and then run some sandboxing to make it be a proper container, but no virtual machines or virtual machine container runtimes* are easier.

Linuxulator, a freebsd project does the above.

*these are much lighter than a normal vm, I'll need to check if this is what macos does. I know for a fact docker on windows uses a full Linux vm though.

Actually that’s a good point that I’ve completely forgotten. Docker uses the modern macOS APIs for virtualization these days, and uses Rosetta2 for amd64 containers.

Edit: Damn you’ve got me excited about FreeBSD again. I’m a much bigger fan of FreeBSD on bare metal but do love Docker and related Linux goodness!

FreeBSD is supporting OCI containers natively. If the app in your container can run on Linuxulator, it will run on FreeBSD (natively on the FreeBSD kernel).

They want it to be able to host Kubernetes on FreeBSD.
