dhcp4d: ensure that SetHostname operates on the correct lease ( #64 )
...
Previously SetHostname could operate on an expired lease, or even on a
lease for a different hwaddr, if the lease for the correct hwaddr
expired and the same lease ID was given away to someone else.
That's though mostly a theoretical concern, given the actual usage of
SetHostname and the time scales involved.

netconfig: de-configure old DHCPv4 addresses from uplink0
...
It is generally not a good idea to have multiple IP addresses on the same
interface unless managing their relative priorities via metrics etc.
During an outage, I noticed that with multiple IP addresses,
Linux was using the old obsolete one to send out packets,
which does not work with the ISP.
With this change,
we still hold on to IP addresses for as long as possible,
but no longer.

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.
