RootfsStrategy

zlayer_agent::runtimes::overlay_rootfs

Enum RootfsStrategy 

Source 
pub enum RootfsStrategy {
    KernelOverlay,
    FuseOverlay,
    FullCopy,
}
Expand description

The rootfs build strategy chosen for a container, given the daemon’s overlay capabilities. Pure selection so the order is unit-testable without building a whole runtime.

Variants§

§

KernelOverlay

Kernel overlay mount (shared layers; needs root / CAP_SYS_ADMIN).

§

FuseOverlay

Rootless fuse-overlayfs mount (shared layers; no privilege).

§

FullCopy

Full per-container copy of every layer (no dedup; last resort).
