Jails for NetBSD

5 hours ago

Demonstrates a minimal workflow using jailmgr, jailctl, and NetBSD base components.
Steps include bootstrapping the host, creating a jail named 'web' with specific constraints, and ephemeral provisioning.
Jails can be started with autostart settings, and processes are supervised by jailctl.
Inside the jail, only processes belonging to that jail are visible, with no cross-jail visibility.
Runtime statistics and resource accounting are maintained by the kernel and exposed via a control interface.
Prometheus-compatible metrics can be emitted for monitoring, using base system facilities.
Highlights include hard resource limits, supervised execution, and no container runtime or UID remapping.
