If you want covering limitations as possible, I'd suggest you to add
these.
- Some versions of GNU find(1) may produce a warning about the link
  count of a directory. When a sub dir exists, find(1) expects it
  increments the link count of the parent dir.
- If I remember correctly, Valerie Aurora has pointed out that
  open(O_RDONLY) + fchmod() will work correctly in UnionMount.
  It is true in overlayfs too?
