Hanna Reitz 9d8f8233b9 qsd: Unlink absolute PID file path ... After writing the PID file, we register an atexit() handler to unlink it when the process terminates. However, if the process has changed its working directory in the meantime (e.g. in os_setup_post() when daemonizing), this will not work when the PID file path was relative. Therefore, pass the absolute path (created with realpath()) to the unlink() call in the atexit() handler. (realpath() needs a path pointing to an existing file, so we cannot use it before qemu_write_pidfile().) Reproducer: $ cd /tmp $ qemu-storage-daemon --daemonize --pidfile qsd.pid $ file qsd.pid qsd.pid: ASCII text $ kill $(cat qsd.pid) $ file qsd.pid qsd.pid: ASCII text (qsd.pid should be gone after the process has terminated.)
