Re: [libvirt] [PATCH 5/6] virtlockd: make re-exec more robust

virtlockd's argv[0] may not contain a full path to the binary, however it should contain something that can be looked up in the PATH. Use execvp() to do path lookup when re-executing ourselves. After re-execution, we must not attempt to daemonize again. It's not only unnecessary, but it also means we end up with the wrong PID and so we can't validate the state file. Instead, build a new argv for the new program that does not include --daemon.
