composefs is an approach to image-mode systems without the disk images. Files are stored in a de-duplicated content-addressed storage with integrity guaranteed through fs-verity. The last year has seen an acceleration of development on composefs-rs, a pure Rust implementation of the ideas behind composefs. Our goal is unification of the storage of bootable system images (via bootc), application Flatpaks, and traditional OCI container environments, bringing deduplication and integrity guarantees to all three. An overview.
