++             (e.g. the "timezone-data-2013f" package in Gentoo)
++            may have synlimks like:
++              /usr/share/zoneinfo/posix/ -> /usr/share/zoneinfo/,
++            so the same timezone files are available under two names

++
++            We allow one level of symlink recursion for backward
++            compatibility with earlier timezone data packages that have
++            duplicate copies of the same timezone files inside the root
++            directory and the "posix" subdirectory (instead of symlinking).
++            This makes "posix/CET" still available, but helps to avoid
++            following such symlinks infinitely:
