FreeBSD has spent the last few years implementing awesome Solaris-based features such as DTrace and ZFS. Here at Wayfair, we use FreeBSD on our servers and our development environments. As a security engineer for Wayfair, I’m tasked with many fun projects. I get to test out different configurations and applications in FreeBSD. Naturally, I set up a FreeBSD 8-STABLE VM to do my testing.
ZFS gives you a lot of flexibility and stability. I decided to go with ZFS on my VM so that I could emulate OpenIndiana’s boot environment (BE) system. For an example on how boot environments work, please refer to the OpenSolaris documentation.
