im going to do something similar. Start9 as my main, mac mini running another and some type of linux running another
Discussion
My Start9 is work in progress.
Everybody raves about it, so I believe I am unique, but, for me, it is missing some critical components and the UI is difficult to navigate.
For one I need a VPN like Tailscale. Tor is just awful to use and I am mostly remote from my nodes, so Umbrel tailscale is critical for my use, both from an admin perspective, but also from a remote spend perspective: Tailscale, + Zeus to access my node.
I understand a new Start9 OS is on it's way with much better UI and a VPN, but I've been waiting for well over a year for it.
