func MachineTemplateDeepDerivative added in v0.12.0 

func MachineTemplateDeepDerivative(new, old *snowv1.AWSSnowMachineTemplate) bool

MachineTemplateDeepDerivative compares two awssnowmachinetemplates to determine if their spec fields are equal. DeepDerivative is used so that unset fields in new object are not compared. Although DeepDerivative treats new subset slice equal to the original slice. i.e. DeepDerivative([]int{1}, []int{1, 2}) returns true. Custom logic is added to justify this usecase since removing a device from the devices list shall trigger machine rollout and recreate or the snow cluster goes into a state where the machines on the removed device can’t be deleted.
