I'll look into that. Thanks!

Umm, while I agree in principle with taking things like this
seriously, an important part of administration is knowing not
only what vulnerabilities there are, but what one's own exposure
may be. So, simply issuing serious warnings and recommending all
to upgrade doesn't give the full story.

No argument here about publishing, and I appreciate it. I'm not
convinced that best practice is always to accept security updates
immediately, or even ever (necessarily). I've seen security
updates retracted.

Oppose globalization and One World Governments like the UN.
