About:
fuse-overlayfs is a FUSE-based implementation of the overlay filesystem, allowing unprivileged users to create layered file systems without requiring root access or kernel support. It provides the same functionality as the kernel's overlayfs but operates entirely in userspace, making it ideal for container runtimes in restricted environments.

Key Features:

Unprivileged operation: runs without root privileges
FUSE-based: no kernel module required
Overlay filesystem semantics: supports layering and copy-on-write
Optimized for containers: used by Podman and other container tools

Use Cases:

Running rootless containers with overlay filesystem support
Building container images in restricted environments
Providing layered filesystems without kernel overlayfs support

Alternatives:

kernel overlayfs – Requires root privileges and kernel module support, but offers better performance
bindfs – FUSE-based but focuses on mount point manipulation rather than layering
