Thank you for the report.

This has been fixed in coreutils version 8.25 - meaning you
are likely using an older version.

Have a nice day,

I'm using a Docker environment which has a rootfs mounted using the
"overlay" filesystem on Linux kernel 4.4.0-141-generic (Ubuntu 16.04) on
amd64.

Inside the Docker environment I tried the usual "tail follow" command:

  tail -f /var/log/nginx/error.log

This spat out the error message:

==> /var/log/nginx/error.log <==
tail: unrecognized file system type 0x794c7630 for
'/var/log/nginx/error.log'. please report this to [email-masked].
reverting to polling

And it seemed to work OK after that.
