ImportPackedImage, a client-streaming RPC that stores an image the caller has already packed (squashfs, erofs, tar or directory) straight into the daemon's image cache, together with its manifest and config. It skips the unpack and repack thatImportImagedoes.The artifact arrives either as chunks or as a
local_pathunder the daemon's temporary directory, which the daemon moves into the cache. The daemon checks the manifest, the config and the digest, but not the artifact's contents.containerd-shim uses it to run mksquashfs straight over containerd's unpacked rootfs, instead of flattening the image to a tar first.
