This trick *usually* works just fine. If, however, you have just
replaced your sshd and restarted the daemon, I've had fascinating
problems with the ssh client used to do the work refusing to exit
gracefully. I'm not sure why this happened, but I've had to handcraft a
tool to do the ssh command to do the remote installation, restart the
daemon, then slap the ssh connection in the head to close it and keep it
from never exiting.
