As a final comment
barti, you will not find
high quality results by searching for OpenBSD-related information using a general-purpose search engine such as Google. Yes, Google may ultimately return hits to information found in the mailing lists, but those hits will not appear in on the first page of search results. The mailing lists simply do not receive enough traffic in order to get a search-order ranking equivalent to their value. This is why most information found the first page of Google searches is dreck.
The best information on OpenBSD is in the archives of the projects' mailing lists. To search the mailing lists specifically, look at any of the archive search engines discussed at the following:
