Function declared 

pub fn declared(d: &UnitDef) -> UnitDef

A manifest entry as the manifest declares it: the fields the module derives cleared. Derived (computed by nix/module.nix from the unit’s own systemd config, exported, never a services.planarian.units option): holds. A change in a derived field alone is no edit to Planarian’s manifest (coordinator, Nov 3); the systemd config behind it is caught where it already is. Every field named, with no ..: a field added to UnitDef does not compile here until it is put on one side.
