The only thing you have (the most) control over is the software you produce, another approach would be to add a generic message facility to all your utilities that, for example, displays the contents of a file at startup (if it exists). Daemon startup could
check the configuration files and generate the content of the displayed file ("You're using 'blah' option which is depreciated, see
<a href="http://">http://</a>..."). This way, if an administrator uses any of your utilities, they see the message. For "extra credit", add a "don't display this message again" option. If an administrator manages to support your software without using any
of your utilities then they are capable of remediating their own problems.<o:p></o:p></span></p>

It’s undermentioned in the policy proposal, but the named-checkconf<br>
will be loud about the deprecated options. We can then bug distros to<br>
integrate the named-checkconf run into the pre/postinst maintainer scripts.<br>
(Hey myself, fix the Debian package. Ok, myself…)<br>

That would take 4 full years to deprecate single option, as we need to take<br>
people that upgrade from ESV to ESV into account, and we were aiming<br>
at slightly “faster” approach :-).<br>
<br>
Thanks,<br>
