Abstract
A computing device executing a kernel-based operating system creates a content-addressed object store containing files of a filesystem. The computing device generates a metadata file that describes characteristics of the files of the filesystem that are in the content-addressed object store. The computing device, in a kernel of the operating system, generates a Merkle tree of the metadata file and a Merkle tree of the content-addressed object store. The Merkle trees contain hashes of blocks of the metadata file and hashes of blocks of the files in the content-addressed object store. The computing device, in the kernel, verifies that a digest corresponding to the metadata file matches an expected digest for the metadata file and that digests corresponding to the files in the content-addressed object store match expected digests for the files in the content-addressed object store. The computing device mounts the metadata file to a location in the filesystem.
