dhcp client recommendations

[John Miller]

Hi Matt,

What sort of lease time are you thinking about giving your clients?
With indefinite retries, are you trying to solve the problem of:

* Clients receiving IPs at boot time before services have started
* Clients renewing their leases post-boot with services running?

Client side is where we have questions, so forgive me if this is the wrong place to ask.  In the case of a dhcp server failure, we were hoping to have clients (CentOS 6/7, Ubuntu 14/16/18.04) retry indefinitely.
