Examples should be concise and give proper hints on how to achieve a reliably working <code>network-online.target</code>.

=== Interface Naming ===

The name of an interface can be changed based on different matches. This is useful for pretty names (e.g. wan, lan), but also if you want to make sure that your interface name never changes. This might be useful because even with predictable interface naming your interface name can change, for example when you add a new PCIe card and indexing changes, or due to kernel changes the way your mainboard gets interpreted changes.<syntaxhighlight lang="nix">

systemd.network.links."10-wan" = {

# Check systemd.link(5) for other matchers

matchConfig.Path = "pci-0000:09:00.0";

linkConfig.Name = "wan";

};
