After writing the PID file, we register an exit notifier 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 exit notifier. (realpath() needs a path pointing to an existing file, so we cannot use it before qemu_write_pidfile().) Reproducer: $ cd /tmp $ qemu-system-x86_64 --daemonize --pidfile qemu.pid $ file qemu.pid qemu.pid: ASCII text $ kill $(cat qemu.pid) $ file qemu.pid qemu.pid: ASCII text (qemu.pid should be gone after the process has terminated.)
