On CentOS 6, there is a test failure: FAIL: tests/tail/tail-c.sh
Log is attached. The command that fails is: timeout --verbose 1 tail -c 4096 /dev/urandom And indeed, I can reproduce it manually: $ timeout --verbose 1 src/tail -c 4096 /dev/urandom timeout: Unrecognized option '--verbose' Try `timeout --help' for more information. $ src/timeout --verbose 1 src/tail -c 4096 /dev/urandom timeout: sending signal TERM to command 'src/tail' $ echo $? 124
