Meeting notes on this topic: We can ref crfs on isulad. Next are works we need to dig more: - integrate crfs with plugin or standalone daemon? - how to detect the wanted image to run is normal image or stargz format? with special MIME type? - integrate with kata: currently 9p+overlayfs should be OK, but what about virtiofs? Modify virtiofs to support crfs? - current POC is using external rootfs to connect to crfs, can we use graphdriver but not external rootfs? These will be followed with issue+wiki on gitee, if progress is OK, we will raise a topic to discuss the design again on next SIG meeting.

It has the great feature on remote items for pulling-smartly-when-needed. With it, the container creating time could be greatly reduced. It is already supported by containerd [3]. I’ve digged some on it, let’s discuss it on this week’s meeting and see what we can do.
