`configuration` seems to be a reference to an argument that was
removed seven years ago in commit 2892aed7.
`configuration.nix` makes it a big more clear what we're referring to.

# From an end-user configuration file (`configuration.nix'), build a NixOS

# Ideally eval-config.nix would be an extremely thin wrapper

|
|
# as subcomponents (e.g. the container feature, or nixops if network
|
|
# expressions are ever made modular at the top level) can just use

# types.submodule instead of using eval-config.nix
