Drop: Demand for Lightweight Linux Sandbox Isolation
Problem
Users seek root‑less isolation of third‑party software to avoid a single compromised dependency compromising the whole system or other users; they desire a lightweight sandbox that is more productive than containers/VMs for local work, offering disposable home directories with selective read‑only mounts; and they need better security boundaries for GUI/hardware‑accelerated applications.
Pain points
- Concern that a compromised third‑party dependency can fully compromise the system
- A single compromised dependency may compromise all users of the software
- Containers/VMs reduce productivity for local development
- Need for disposable home directories with selective read‑only mounts
- Insufficient sandboxing for GUI/hardware‑accelerated applications
- Desire for finer‑grained security controls such as network allow‑lists and credential masking
Questions to verify
- Do you need to isolate third‑party programs without using root?
- Are you currently facing productivity bottlenecks with containers or VMs for local development?
- For GUI/hardware‑accelerated applications, do you want sandbox security contexts similar to Flatpak?
Evidence

I always felt uneasy installing and running third-party programs using my main user account. A single compromised dependency means a full compromise of the system.

Can you explain a bit more about the boundary between the environment and my system? Is it just giving read-only access to /usr/lib?
