Yes.  On my bouncer box, I just do a make installworld and I don't
worry.  For a production machine, I'd likely kill inetd, sendmail and
httpd before doing this.  ftpd too if necessary.

No.  Bad idea.  If you have 20 identical machines, then maybe the
other 19 wouldn't be a bad risk.  But on the first one, you should be
there.
