Definition
A userspace OS is a shared library implementing OS concepts in user space. Each container can run its own isolated instance, similar to gVisor’s Sentry.
Key Points
- ftl-os uses hypervisor-like kernel with per-container userspace OS
- CPU user-mode isolation without hardware virtualization
- OS upgrades via container restart, not host reboot
FTL v0.1.0 is pre-alpha; production readiness unverified.
