See https://github.com/google/crfs for details.

CRFS was proposed in golang/go#30829 to enable clients to launch containers without having to pull the entire image locally. Especially in an environment like GCP this becomes quite feasible to do in terms of network performance.

Nixery could support CRFS by implementing support for the stargz format (for which an io.Writer is provided in the CRFS repo). CRFS has a strategy for dealing with container runtimes that don't (yet?) support it, which involves also creating some metadata-only layers. This behaviour can probably be toggled by introducing a /crfs meta-package.
