Why is "kill -HUP 1" unsafe? It's documented in init's manpage:
Line status (on, off, secure, getty, or window information) may be
changed in the ttys(5) file without a reboot by sending the signal
SIGHUP to init with the command ``kill -HUP 1''. On receipt of this
signal, init re-reads the ttys(5) file.
