Sister communities:


Community rules (click to expand)

1. Follow the site-wide rules

2. Be civil
  • Understand the difference between a joke and an insult.
  • Do not harrass or attack members of the community for any reason.
  • Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
  • Bigotry will not be tolerated.
  • These rules are somewhat loosened when the subject is a public figure. Still, do not attack their person or incite harrassment.
  • 3. Post Linux-related content
  • Including Unix and BSD.
  • Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of sudo in Windows.
  • No porn. Even if you watch it on a Linux machine.
  • 4. No recent reposts
  • Everybody uses Arch btw, can't quit Vim, and wants to interject for a moment. You can stop now.
  •  

    Please report posts and comments that break these rules!


    Important: never execute code or follow advice that you don't understand or can't verify, especially here. The word of the day is credibility. This is a meme community -- even the most helpful comments might just be shitposts that can damage your system. Be aware, be smart, don't fork-bomb your computer.

    Yeah, that should work too... but you don't get to see any of your local files...

    Made a Nix library for this. For a simple setup you can just build this (untested) and run the result:

    import ./encase.nix {
      name = "firefox";
      rw.home.nathan = /home/nathan/home-for/firefox;
      # other dependencies it might need...
      tmp = /tmp; # fresh tmpfs for this sandbox
      network = true;
      command = pkgs.firefox;
    }
    

    It doesn't have user isolation yet, so if it escapes the browser and the chroot (which doesn't have a /proc unless you set proc = /proc;, and runs in a PID namespace either way) your files are still at risk. However, this is still pretty secure, and you can run the script itself as a different user (it creates a new UID namespace so chrooting can be done without root).
