Should I keep Private and Non-Private Apps on different OS's?

Privacy Questions

Hello Forum!

I understand Linux has poor sandboxing capabilties, so i was considering duel booting 2 seperate Fedora instances, with one for private Foss apps and one for anything else. (Similar to User Profiles on GrapheneOS)

A couple of questions though

  1. Do privacy-shakey apps on Linux such as Discord or Steam really passivley look into other apps data or is seperating them only a measure to prevent targetted attacks.

  2. Why is this not recommended on the main site?

  3. Is it ok to even sign into website i would like to keep private on a OS with unprivate apps?

Just challenging the design, couldn’t you maybe consider using Docker or a VM? Do you really need to dual boot?

Even with GPU passthrough, i don’t think a VM would work well enough for consistant Gaming/Video Editing

On the other hand, I never really considered using Docker for desktop Linux. Is it really as private as 2 seperate os’s on 2 seperate drives?

Why not? With GPU passthrough, you can allocate a dedicated GPU to the VM, allowing it to perform nearly as well as if it were running natively. This is particularly beneficial for gaming and video editing, which are resource-intensive tasks.

No, it is not but do you really need that? What is your threat model? What are you planning to isolate?
