Well, my question is more about how the app can run in its current version without me seeing a relay.

I update my servers very promptly and have never had a problem with a version jump. Apt handles this well.

Icinga and Phare Uptime

Which source is the stream reading from?

Secure Boot is unfortunately always a bit of a hack on Arch.

I don’t really have a favorite; I offer a lot of software to the public for free use. Ansible and Proxmox are really helpful for me in doing that.

Just installed via Ansible and it’s running without any issues so far. As far as I could tell visually, it’s running much faster.

I like EndeavourOS a lot, that was my start in Arch.
