Enum RootfsSource 

pub enum RootfsSource {
    Bind(PathBuf),
    Oci(OciRootfsSource),
    DiskImage {
        path: PathBuf,
        format: DiskImageFormat,
        fstype: Option<String>,
    },
}

Root filesystem source for a sandbox.

Variants

Bind(PathBuf)

Use a host directory directly as the root filesystem.

Tuple Fields

0: PathBuf

Host path to bind mount.

Oci(OciRootfsSource)

Use an OCI image reference with an EROFS lower and ext4 overlay upper.

DiskImage

Use a disk image file as the root filesystem via virtio-blk.

Fields

path: PathBuf

Path to the disk image file on the host.

format: DiskImageFormat

Disk image format.

fstype: Option<String>

Inner filesystem type (optional; auto-detected if absent).
