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? J. R. Okajima
