    I’d just like to interject for a moment. What you’re referring to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.

    Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called “Linux”, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project.

    There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called “Linux” distributions are really distributions of GNU/Linux

    You are correct that this is technically in code and would protect against shock hazards in a neutral error situation but you also get the opportunity for the outlet to pop during the day when nobody is home and the battery to die.

    We had a situation in our old house where someone who was technically correct but didn’t think it through had a gfci outlet upstream of the refrigerator outlet. Thankfully it popped while someone was home and we got everything corrected before we lost everything in the fridge.

    1. The order doesnt matter as long as they are the same drives, you dont have a usb dock or raid card in front of them (ie sata/sas/nvme only)and you have enough of them to rebuild the array. Ideally all of them but in a dire situation you can rebuild based on 2 out of 3 of a Raid Z1

    2. You can do that, you shouldn’t but you can. I’ve done something similar before in a nasty recovery situation and it worked but don’t do it unless you have no other option. I highly recommend just downloading the config file from your current truenas box and importing it into a fresh install on a proper drive on your new machine.

    3. Sort of already mentioned it but you can take your drives, plug them into your new machine. Install a fresh Truenas scale and then just import the config file from your current setup and you should be off to the races. Your main gotcha is if the pool is encrypted. If you lose access to the key you are donezo forever. If not, the import has always been pretty straightforward and ive never had any issues with it.

    4. Lots of people virtualize truenas and lots of people virtualize firewalls too. To me, the ungodly amount of stupid edge cases, especially with consumer hardware that break hardware passthrough on disks (which truenas/zfs needs to work properly) is never worth it.
