Hey
I'm preparing a macOS NAS setup on a mini with an internal SSD and a bunch of external USB drives. My plan was to just create my pool on the USB drives that are already assigned for this task, but for the last day or so I've been looking at options for doing cloud backup (cheaply).
I've been following Backblaze's blogs for quite a while, and really think what they're doing is awesome. I'd love to be able to use their service (not the B2 one; too expensive), but I've tried to back up stuff that's on ZFS, and their app won't do it.
This got me wondering if it might feel different if the pool was actually the root filesystem. So I thought about this whole installing macOS on a zpool thing (https://openzfsonosx.org/wiki/ZFS_on_Boot), but I do notice that the guide is using El Capitan in its examples, so I'm wondering if it's still a (supported) thing. I've been setting up Mojave on the mini, but I'm not at all married to it. I'm actually running Yosemite on another mini — the only requirements I have for the OS version is that I can run ZFS on it, and that homebrew works enough for me to install GNU coreutils and other shell tools that I use extensively. Oh, and the mini in question is a 2014 one, so El Capitan will install on it if necessary.
Thanks!
