I suspect it's related to the issue you mentioned in Documentation of overlayfs: -- Symlinks in /proc/PID/ and /proc/PID/fd which point to a non-directory object in overlayfs will not contain vaid absolute paths, only relative paths leading up to the filesystem's root. This will be fixed in the future. -- Could you please help to take a look at this? or point me out some hints.
