I have been using linux for quite some time now, usually Ubuntu these days, but have used Debian and Gentoo too, and have been meaning to get started with FreeBSD for a long time.
While both are very similar at the user level (I used FreeBSD systems in college, and never noticed much of a change once I installed linux at home), are there any good guides that give the main differences in terms of setting up FreeBSD systems if you are familiar with linux. I have also heard very good things about FreeBSD, especially from the college sysadmins, and the fact that you can run ZFS with FreeBSD relatively straightforwardly has given me the impetus to try it out.
I am sure there are a number of gotchas involved though, so was wondering what guides / sites exist for this - assuming they exist?
