Actual API is implemented in the `init`, as it has access to root filesystem. `osd` proxies API back to `init` with some tricks to support grpc streaming. Given some absolute path, `init` produces and streams back .tar.gz archive with filesystem contents. `osctl cp` works in two modes. First mode streams data to stdout, so that we can do e.g.: `osctl cp /etc - | tar tz`. Second mode extracts archive to specified location, dropping ownership info and adjusting permissions a bit. Timestamps are not preserved. If full dump with owner/permisisons is required, it's better to stream data to `tar xz`, for quick and dirty look into filesystem contents under unprivileged user it's easier to use in-place extraction.
