The first time I installed OpenBSD I didn't know what to enter as "host name", nor that I needed to make a hosts file entry for whatever I chose.

Another example might be when startx stopped working for non-root users - a "change / why / what to do now" explanation would have been handy.

But OpenBSD isn't aimed at Unix newbies so it's entirely understandable why that level of hand-holding doesn't exist.
