Show HN: NSL – WSL for Linux

https://frostyard.github.io/nsl/
16•bketelsen•2h ago
One of the things that Windows really got right is WSL2. I drive an atomic Linux distro for daily use, but wanted a way to develop with multiple different distros with that same WSL UX. NSL is my answer. It is a faithful reproduction of the developer experience, powered by a single VM that hosts one or more systemd-nspawn containers with your development instances. Host file edits and port sharing come along for the ride, just like WSL. Take a look and tell me what you think... It's yet another step in my long journey to keep my host installation free from all the changing and breaking dev dependencies that force a reinstall every few months.

How does this compare to distrobox?
bketelsen•3m ago
Distrobox mounts $HOME in the container at $HOME by default. WSL and NSL do not, and that's my preference. This means you can install tools that change your default path, change your dotfiles, etc, without affecting the host. The other obvious difference is that distrobox is powered by podman or docker, while NSL uses a VM that runs systemd-nspawn containers.

IS it LXC containers or docker? Or are you running a custom chroot namespace setup?
mhitza•35m ago
Haven't checked the actual project but he does state he uses systemd-nspawn. Which is it's own kind of container runtime.
smw•26m ago
He runs a systemd-nspawnd container in a "small vm", so neither really?

The project is cool, but please use human written text.

The website's Claudisms are unbearable.

This is most useful to people who run Linux as their daily driver so rather than saying its like WSL can you explain what it offers that existing Linux containers do not?

Its also sounds different from WSL which I thought is a VM rather than a container.

Something that also require a bit of explanation. What do you do that makes this such a common problem.

So you've just basically reimplemented LXC?
pkulak•10m ago
Nope. This is a VM, with containers inside. And the containers weren't "re-implemented", it uses existing systemd containers. That's what I was able to learn by skimming the site for 30 seconds. Did you not even do that? And why even be so condescending to someone else's project?
ktm5j•5m ago
Because it does seem like we already have tools that skin this particular cat, it's valid to wonder what value this project provides over existing solutions.. even if they chose the wrong example to compare it to. Why do you think that's condescending?
RandomGerm4n•23m ago
There's already Distrobox, which does exactly the same thing but isn't slop.

I have to say this is nice packaging. It is weirdly not obvious how nice it is to cleanly use a different “machine” inside your desktop.

I never thought I’d prefer WSL to even my MacBook for working with remote servers and dev but somehow I do.

I of course know the many ways to roll something like this for myself, yes dev containers are better for many things etc. but it’s wierd how good the ergonomics of a WSL like container are.
