Subject: bug#47935: coreutils: tests/tail-2/inotify-dir-recreate.sh fails on overlayfs
Date: Wed, 21 Apr 2021 11:35:50 -0400

Hi all,

I’m continuing my testing of the 1.3.0 branch, and I’ve found that coreutil's tests/tail-2/inotify-dir-recreate.sh fails on filesystems where tail detects that it cannot use inotify safely (probably arising out of this check: https://github.com/coreutils/coreutils/blob/34a48bf0f0552aaed21a7dba4a5488946a978317/src/tail.c#L2486-L2491). Example for this: overlayfs used by docker/podman/etc.

The author of tail’s inotify support explains it here: https://github.com/containers/podman/issues/5493#issuecomment-598851397

A quick and easy fix for v1.3.0 may be to just disable tests/tail-2/inotify-dir-recreate.sh :-)

Cheers,
Carl Dong
