Getty(8) has been changed in a couple of ways.  First, it now attempts to
detect noisy lines and turn them off temporarily.  And second, it now looks
at /etc/nologin and, if it is non-empty, prints it out and refuses to exec
login.  The backup-warning system has been set up so that it turns off
logins when it issues the please-sign-off-now message at 1759, and /etc/rc
turns logins back on.  Selected terminals are exempt from this to allow
dealing with emergencies.

The /etc/nologin check probably belongs in login rather than getty,
but I didn't think of that until I had it all set up.  I will fix that
eventually.
