This is not a fatal error, but rather a kind of warning message.

Next time, please also report the coreutils version.

overlayfs - commonly used with Docker containers - has been added
in version 8.25. Consider upgrading Coreutils if possible.

See https://www.gnu.org/software/coreutils/filesystems.html for

Have a nice day,
