It appears race condition in reading/writing daemon.log is not the only issue of t5570. On a different machine I've just randomly got: t5570-git-daemon.sh[163]: can't create git_daemon_output: Interrupted system call which I believe might also be associated with concurrent processing of piped data connected with a fact that test restarts daemon few times. I can barely wrap my head around it but I guess it's somewhat around "shell still tries to read fifo while attempt to create new one is made". Regards Jan
