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 bug-coreutils@gnu.org. reverting to polling And it seemed to work OK after that.
