Unless you wanted the searching to stop at symlinks and mount points,
which I usually do, at least for my own usage.
It may or may not be useful. In AFS you can know that odd inodes are
directories, whether or not that's sufficient for your applications.
You can also know that all directories in the current volume are odd
inodes. And that symlinks and mount points are even inodes.

Unfortunately, true. And kind of fundamental, since DFS can export
native file systems such as UFS, which themselves don't have an even/odd
rule.
