I just wanted to share my Ignition Experience with the Linux Operating System.
For folks who are wondering if Ignition works on Linux, the answer is YES!
I have been implementing production Ignition systems for a few year now. From Ubuntu server 20.04 to 22.04, using on Fedora 29/39, using on Rocky8/9, also using ignition on Ubuntu arm64 version for my Mac M3. I know MacOs is technically a linux hybrid but I have Ignition running on an Apple Server (intel chip) with High Sierra OS. I have not tried it on an Arch distribution but as posted in another thread, I got it working on a Steam Deck with runs a custom arch version of SteamOS.
Long story short, don't hesitate to use Linux and run ignition in Production on Linux!
LXC containers under Proxmox work great w/ Ignition. You can use the .run installer. Since they're system containers, they've got full systemd and everything installs like on a normal Ubuntu VM.
