Chapter 16: Upgrading OpenBSD
Overview
The latest source code?
Fugu extraordinary!
Be brave and swallow.
System upgrades can make even seasoned systems administrators wish they had a simpler job, such as taming rabid weasels. While you can probably deal with a bit of odd behavior in a desktop system after an upgrade, your network firewall and servers must behave as expected. Many sysadmins avoid the whole issue by delaying upgrades as long as possible, until the system is old enough that it can be replaced with a new machine running a clean install of the new release.
Not only is this expensive, but it's very bad from a security standpoint. Computer systems must be patched, maintained, and upgraded, or an intruder will almost certainly compromise them.The OpenBSD upgrade process isn't nearly as difficult as that used by many other UNIX-like operating systems, and is far more reliable than that used by many other operating systems. With proper preparation, you can upgrade your OpenBSD systems with a minimum of difficulty.
