Remember to fix this when you rename the property.

Why's that? Is that an intrinsic requirement of DAFT or is it because
DAFT wants to use certain devices that are typically owned by root? Can
we instead make the requirement that the user running daft has
permissions and groups correctly configured to access these devices?
