Ah, reserving a filename prefix ".wh.". I see.
Thanx for the explanation.
By the way, putting extra things under lost+found is not a good idea I
think.
Have you ever tried restoring files manually from lost+found?
When an administrator meets such case, he will digging lost+found and
copy the files one by one with guessing the filenames. If he is not sure
what the file is, then he may leave it under lost+found.
For such case, the entries related to overlayfs will be left, and the
administrator will spend some sleepless nights with thinking "What are
these files? How can I restore them?"
