Please don???t denigrate my knowledge, as so far as I know, we???ve never met, and nothing I said warrants such. The installer reminds me of Redhat???s old anaconda installer, I???ll grant you it???s dated. However, I typically install a new linux distro every week and there are many, many installers that are far more confusing - Open Suse and Fedora are two that come to mind, Debian as well. I would hazard to guess your favorite Linux is based on a distro that lacks a decent installer (Ubuntu and Mint are Debian based).

Now that Linux has ZFS, it doesn???t seem as stuck in the dark ages, but uptime on my fbsd instance is 10x any of my Linux instances. We are soooo off topic, I think :). But, I???m always up for talking up FBSD. I use it in my classes, too and the system is much more coherent for my systems programming classes than linux.
