Agreed.
Aufs is providing two options for this issue, "diropq=always" and
"diropq=whiteouted". Several years ago, the default was "always". But
soon it changed to "whiteouted" and I have never received objection
from users.
As for as I know, some users are happy since the number of whiteouts was
reduced. Because they merge layers manually for system
maintenance. Unnecessary whiteouts are not good to them.
