53c495091e quirk: enforce minimum lease time of 1 hour for Nintendo devices 
The Nintendo Switch has been observed to hold on to IP addresses even after
their expiration. My guess is that this is an oversight: likely the device
enters power saving mode with a configured IP address and just sleeps through
the expiration time.

As the device seems to wake up once every hour, we enforce a minimum lease time
of 1 hour, but only for affected devices. The rest of the network gets short
lease times.

This can be used to permanently override a hostname, regardless of whether the
