Landlock: What Is It?
Landlock is a Linux API that lets applications explicitly declare which resources they are allowed to access. Its philosophy is similar to OpenBSD’s unveil() and (less so) pledge(): programs can make a contract with the kernel stating, “I only need these files or resources — deny me everything else if I’m compromised.”
It provides a simple, developer-friendly way to add defense-in-depth to applications. Compared to traditional Linux security mechanisms, Landlock is vastly easier to understand and integrate.
This post is meant to be an accessible introduction, and hopefully persuade you to give Landlock a try.

Here is a sandboxing tool using that feature
Landrun as well, takes the restrictions on the command line. Can look messy, but does make it entirely standalone, so you can e.g. drop it into a service file as the readme shows easily enough.
