I was setting up a modded minecraft launcher for the family to use and and I have trust issues with the modding ecosystem and kids installing random jar files. I used bwrap and it works really well. The launcher uses wayland, minecraft typically X, needs dri access for opengl, pipewire, input devices, networking and dns resolve to connect to servers etc. Doesn't need filesystem access to much other than some shared libs (ro) and a directory in .config. There is a bit of trial and error involved and making the bwrap robust to differences between desktops (different sockets for dns or mdns resolvers) and makes me appreciate apps packaged as flatpak as this level of sandboxing should be standardised for all distributed apps. Half the stuff in AUR should be bwrapped IMO.
Linux
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.

I've been meaning to set up sandboxing, this is super helpful! Thanks
Does anyone happen to know if bubblewrap is more powerful than bubblejail (or vice versa). Or how they differ in the first place (beyond CLI vs GUI)?
bubblejail is based on bubblewrap.
