Enum SnapshotRootDisk 

pub enum SnapshotRootDisk {
    Managed,
    Flat,
    Tmpfs {
        size_mib: Option<u32>,
    },
}

Guest-visible OCI root-disk layout captured by the snapshot.

This is required because a one-layer raw disk can either be a managed OverlayFS upper or a complete flat root filesystem. Those byte payloads have different attachment and restore semantics even when their physical layer shapes happen to match.

Variants

Managed

Immutable OCI lower layers plus a writable managed upper device.

Flat

One complete filesystem attached directly as the guest root device.

Tmpfs

An OCI lower with a writable upper held entirely in guest memory.

Fields

size_mib: Option<u32>

Configured tmpfs ceiling in MiB, or the runtime default.
