A ZArchive named app0.zar beside app0/ is a read-only layer under it. libc opens it at the first path resolution, looks paths missing from app0/ up case-insensitively, reads files across compressed blocks and keeps the archived descriptor table with shared positions. Resolving an archive-only path through a call that does not read the archive throws instead of failing with ENOENT, as do opendir of a directory present in both places, fdopen of an archived descriptor and chdir into the archive. A path through .. in an archive-only directory resolves.
