If these pods are evicted, they loose all knowlage of exsisting dhcp leases, and any pods using dhcp ipam will fail to renew the dhcp lease. even after the pod is re-created.

    1. use a NAD with ipam: dhcp.
    2. delete the dhcp deamon pod on the smae node as your workload.
    3. observe the lease expire on dhcp server / get reissued to a different pod causing network outage from duplicate addresses.
