Please tell us more about your question or problem

When using multiple inputs which themselves have nixpkgs entries, a situation will occur where the flake.lock would need to refer to nixpkgs twice, once for the flake input and ones for the flake input's input. flake.lock solves this by populating nodes.root.inputs with key=value of name=alias.

Renovate only checks nodes against the key/name and if it matches, attempts to update that node. This can cause mismatches, it should actually use the alias to determine if a node is a root node.

https://github.com/tebriel/renovate-repro has a minmimal repro.
