I love this thread, nice!

So I have a few machines at the moment. A laptop, a desktop, a server, some raspberry pis, and a phone. I have other machines that could be used eventually, but this is what I have at the moment.

My setup is currently evolving. I have FreeBSD on the server, and my main user installed at /usr/halfwit... and I share /usr on the network, which allows my desktop to mount that. The end result is that my desktop and my server have the same set of "my files", differing only in what binaries are installed for the system runtime, thanks to how FreeBSD decided to break this all out. My laptop is stil running macOS, but I want for it to join the fray sooner than later.

I use plan9, which i'm attempting to coerce to live on FreeBSD. Basically, Plan9 is a file server, authentication server, computing server, and terminals which utilize these resources. They can be all done on a single piece of hardware, in a single installation; or broken out across disparate machines as you care to. What I want is to move the file server over ZFS on my FreeBSD. This allows me to boot a machine to run the duty of 'authentication' on say, an rpi, and then only really need to virtualize the CPU server section, which is very nice, I can do that on-demand, on another rpi, anywhere really, and use the Unix userland utility Drawterm to act as my terminal in most cases. As for switching machines, well, that's what Altid is truly great for.
