Some comments on FreeBSD 5.2 usage
I personally manages several FreeBSD 5.2-CURRENT instances, and here are my experiences.
FreeBSD 5.x contained many new features, technologies. Currently, it’s clear that 5.2-CURRENT is more stable and have a better performance than 5.2(.1)-RELEASE. Therefore, if you are looking to install a new (of course, and ONLY if you choose 5.x series!) computer, the best solution would be 5-CURRENT.
