I pre-ordered a copy of
OpenBSD 5.6 a while back. It arrived a few days ago, and I lost no time in installing it at work. I've also just installed it on my Lemote Yeeloong to play around with at home. It really is a fantastic system to work with.
OpenBSD is a project I've had an idle interest in for some time, and with all the drama around systemd going on in Linux-land at the moment, it's finally got me fed up enough to move. It's going to take a while before I can move my home desktop, because OpenBSD can't read Linux encrypted filesystems and I have about 2 TB of data to migrate, but I'll get there in the end.
Moving from Linux to OpenBSD reminds me of when I first migrated from Windows to Linux; aside from a few teething problems as I get used to the differences, everything seems much cleaner and simpler, and it's a lot easier to understand how the OS works. This is made even easier in the case of OpenBSD, due to a combination of them including the full source code for the operating system when you buy a CD, having very high standards for their own code, and having documentation that is second to none. I've had it installed less than a week, and I've already spent a while exploring the internals of the codebase, and it's all very neat and tidy.
You can obtain a copy from
http://www.openbsd.org/, although I would encourage you to buy a copy from
https://www.openbsdstore.com/ if you're going to install it, as CD sales are one of the primary sources of funding for the project. I'm enjoying it enough that I already plan to buy OpenBSD 5.7 when it comes out in May.
