- * XXX
- * Because of the way that fts(3) works, logical walks will not count
- * the blocks actually used by symbolic links. We rationalize this by
- * noting that users computing logical sizes are likely to do logical
- * copies, so not counting the links is correct. The real reason is
- * that we'd have to re-implement the kernel's symbolic link traversing
- * algorithm to get this right. If, for example, you have relative
- * symbolic links referencing other relative symbolic links, it gets
- * very nasty, very fast. The bottom line is that it's documented in
- * the man page, so it's a feature.
