2 Simulate a migration from a single-instance `services.foo` to a multi instance
3 `services.foos.<name>` module, where `name = ""` serves as the legacy /
4 compatibility instance.
5
6 - No instances must exist, unless one is defined in the multi-instance module,
7 or if the legacy enable option is set to true.
8 - The legacy instance options must be renamed to the new instance, if it exists.
9
10 The relevant scenarios are tested in separate files:
11 - ./doRename-condition-enable.nix
12 - ./doRename-condition-no-enable.nix
