I don’t know if I want a project as cool as Proxmox owned by the “you will use snap and you will like it” Canonical

NixOS allows me to back up all the configuration for my entire complex hypervisor server by just saving one folder, since it centralizes all system configuration in /etc/nixos. That is an absolute godsend.

And that’s just one example, practically any NixOS installation is easily reproducible by just grabbing the configuration files from that folder. It makes configuring a new install a breeze.

Usually OnlyOffice though I keep LibreOffice installed as a backup as sometimes I’ve had weird compatibility issues with the former (very few and far between but still)
