In thinking about upgrading a qpsmtpd installation I once again ran
across the issue that I can't just copy the plugins dir over my old
one, as I have plugins that I have modified, and my own plugins.
We got around this with config by creating config.sample/
So here's a proposal. Create a new directory plugins.usr that will be
looked in first for plugins. When you want to modify a plugin just
copy it to plugins.usr and edit it. When you create a new plugin, put
it in plugins.usr/. When you upgrade then you can just copy over
everything.
