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