Host access to guest Docker data (~/ArcBox)

[PeronGH]

Overview

Mount the guest VM's Docker data directory as a read-only volume at ~/ArcBox on the host, giving visibility into container images, layers, and volumes without SSH.

Status

Deferred. The underlying transport (NFS over vsock) is partially implemented but has an unresolved guest-side issue. Tracked internally in ABX-155.

Design

The mount uses NFSv4 routed through vsock (the same transport used for Docker API proxying), so it works regardless of VM network configuration.
