This is the sequel to my article Keeping Freebsfs Up-To-Date. The new article takes the same case-based approach I used in the first paper. The article’s sections show commands to run, explanations of what they do, sample output, applications versions, and pros and cons of each upgrade method. Please send feedback to taosecurity at gmail dot com. When I get a chance, I will test putting ‘BATCH=YES’ in /etc/make.conf to update ports with vulnerabilities.”]
