Modern network configuration on Linux
summary
Shows how to replace fragile ifup scripts with declarative tools: Linux System Roles (Ansible playbooks that push NetworkManager profiles at scale) and nmstate (YAML declarative state, nmstatectl, libnm backend). Demonstrates creating bonds, bridges and VLANs, applying changes with automatic checkpoint and rollback and runtime verification so bad configs revert. Notes nmstate integrates with NetworkManager via libnm, warns systemd-networkd conflicts, and says change history is not yet recorded.
