[Isulad] Discuss on #I1JAH2: [Feature-request] Smart loading for remote images

Hi iSulad owners, About #I1JAH2: [Feature-request] Smart loading for remote images, we've got some progress. I would like to raise a topic on tomorrow's SIG meeting, to discuss those known issues and invite you to review the design doc. Those are left on last SIG meeting: - 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? Best Regards, Lu Jingxiao
