Research direction
Start with tests/by-util/test_tail.rs around line 4853 and run test_tail::test_follow_when_files_are_pointing_to_same_relative_file_and_file_stays_same_size repeatedly. Inspect the tail --follow=descriptor invocation and its stderr handling to determine why the intermittent file-truncated message appears. Done means the test is reliable and no longer reports an erroneous warning for this scenario.
