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.

Best ways to Sandbox a sketchy Game on Linux? (sh.itjust.works)

What are the best ways to run a game on sandboxed mode with only game HDD shared to it. There should not be network access for the game and there should be GPU (intel integrated) pass-through.

I have tried Gnome boxes, but GPU pass through is not working and checked distrobox, but that too shares HOME folder.

Fitejail is a large SETUID binary which weakens security and can aid in privilege escalation. Use Bubblewrap (preinstalled on most Linux systems cus of Flatpak) which runs unpriveleged. Bubblejail is a program that makes it easier to make sandboxes profiles for apps.

Oof, I didn't know that about firejail. I'd heard of it, but I'd never used it. Like, c'mon folks! If you need privilege escalation, either require launching as root (if appropriate), or delegate the responsibility to a small, well-audited tool designed explicitly for the purpose and spawn a new privileged pid. Don't use SUID. You will fuck it up. If you reach the point where setuid is your only option, then you've hopefully learned enough to rearchitect to not need it, or to give up, or use it if you're, say, someone who maintains a libc or something.

EDIT: this is overly dramatic, but also it's not. I personally feel like using SUID is kinda like rolling your own crypto in terms of required competence.
