Just don’t use any command in proxmox. Proxmox is designed GUI first. It got an update button in the GUI. Only major releases could need tinkering in the terminal. But even changing repos is now possible in the GUI.

I completely forgot secureblue. But it was not worth the hassle for my working environment

Why is Fedora atomic not more secure? It is literally immutable. Which kills the concept of persistent malware, unless they archive a complex exploit chain to gain root and install a malicious package and then reboot into the new iso, which is easier said then done.

Privacy or Security? Security would be something like Fedora Atomic. Privacy (and security?) QubesOS , TailsOS But as Linux is FOSS, you can just take any distro and form it as you like.

I used Nessus for a while and I heard that OpenVAS could be a good FOSS alternative to it.

Oh and the i2c etc stuff, I connected ESP32 and other microcontrollers over USB.

I have an old pentium laptop N3520 with 4GB DDR3. I removed everything and put it in a receiver box 1U size. It consumes so little energy that it can run 5-7 hours from its battery (I call it build in USV). Last time I measured 3-7w. Also passiv cooled , no noise. Another machine I use , is with a i7 4770 with 16GB for Proxmox, 7-20w , peak is much higher but rarely used , only on boot and vm startup.
