When the daemon process or the host running it is abruptly terminated, the layer metadata file can become inconsistent on the file system. Specifically, `link` and `lower` files may exist but be empty, leading to overlay mounting errors during layer extraction, such as: "failed to register layer: error creating overlay mount to <path>: too many levels of symbolic links." This commit introduces the use of `AtomicWriteFile` to ensure that the layer metadata files contain correct data when they exist on the file system. Signed-off-by: Mike <mike.sul@foundries.io>
