This will be very useful! TIL FreeNAS is now TrueNAS.

Actually there's more! A new version of TrueNAS is in the works, it's called TrueNAS scale and it's going to be Linux-based (no more FreeBSD). I'm frankly happy, because TrueNAS is great as a NAS operating system but I really wanted to run containers where my storage is and having to run a VM adds a really unnecessary overhead (plus, it's another machine to manage)

  TrueNAS supports creation and management of FreeBSD jails through its WebUI.

  Ah, so Linux is approaching feature parity with FreeBSD jails?

    I'm not sure that talking about feature parity even makes sense. What do FreeBSD jails do that Linux can't? I know there's no single jail system call that you can call so you need to assemble the container "manually", but that's an implementation detail as far as I am concerned. On the other hand, true network namespaces (VNET on FreeBSD) have been usable on Linux for longer than on FreeBSD. It's a bit disingenuous to say that Linux is the one "approaching" feature parity when they're both missing features that the other has.

      Ah, that bait got you. It's a smug comment that claims something but offers no example at all, not even an anecdotal one. If FreeBSD jails were so much better than Linux namespaces/containers etc we would be all using FreeBSD by now. The license is even more permissive. Containers have been out for ~ten years now and yet... Here we are.

        And if ZFS was so much better than Linux ext3 we would be all using Solaris, right? ;-) The market doesn’t work like that.

        I suspected it was bait, but FreeBSD jails being better than whatever Linux has is such a common meme that I'm asking anyway just in case someone actually knows enough about them to answer. I don't know enough to say for sure, but my current impression is that Linux namespaces are actually more powerful than jails, but harder to use because the kernel doesn't provide a "simple" interface to create an isolated container, and userspace software implementing containers get to use the individual bits as they see fit.
