Question:
* Will "postfix upgrade-configuration" install a backwards-compatible
override when upgrading systems in which the parameter is not set
in main.cf? And in fresh installs will the parameter be explicitly
set to "no"?
[ We don't have a "configuration version" parameter in main.cf, so
we don't know which configurations need crutches, and which don't. ]
