roleOptions property
The values of role options by name, which smf create gets as its
options (createArguments).
An app has none for a mode option (see RoleOption.mode) with its
first value, unless the options of every app of the matrix give one:
the role chooses the first value without the option, so the matrix
generates the app as a user who does not give the option does.
Implementation
final Map<String, String?> roleOptions;
