netretry previously would only retry in one specific case (your MAC address is not set) and no other. This is basically useless. In the DM implementation for eth it turns this into a completely useless case since an un-configured MAC address results in not even entering the NetLoop. The behavior is now changed to retry any failed command (rotating through the eth adapters if ethrotate != no).
It also defaulted to retry forever. It is now changed to default to not retry
That last bit seems like a big change. Does it mean that if I forget to plug in the Ethernet it might not recover?
It seems like it at face value, but this actually is far closer to maintaining existing behavior.
As described in the first paragraph, only a missing MAC address would be retried. all other forms of failure (unplugged Ethernet, for instance) would just error out. This provides a way to retry if that is a behavior you want. Most times if you ping an address, for instance, you would expect your script to get a failure code, not for the ping to be attempted on a different interface (which would become the new default behavior without this env var default also changing).
