kerasi, I'm going to reiterate
jggimi's first point by emphasizing again the importance of
backing up critical data. As a newcomer to OpenBSD, you will undoubtedly make mistakes. Everyone new to an unfamiliar to a new environment will. Save yourself the agony of losing what can't be replaced by backing it up now.
The OpenBSD community is small, & much responsibility is placed on its users to pro-actively learn how to use it. Studying the
official FAQ is not just a platitude, it is a requirement.
