Systemd has stated this is not their problem: See bug report 883829 and 88167. My value here is testing. I'm happy to test any proposal and provide the results. It is my problem, because Debian Stretch has introduced this behavior. wheezy and jessie did not exhibit this behavior.
My view is: If there are to be large changes , new interface names, mounting
file systems not devices, and asynchronous startup
then the authors of these changes have the responsibility for their quality.
It is not amusing to be caught in the cracks between Debian components.
Please discuss this among yourselves to resolve the issue.
I'v added bug 881675 to the issues. It appears somewhat related.
Please let me know what you need in the way of diagnostic information and
testing.

Is that a regular DNS name? The .local LTD is reserved for mDNS, so
it's not good practice to use it for regular DNS. But I doubt that has
anything to do with the problem.
As you say resolv.conf is built during boot, I assume the DNS server is
remote and is discovered through DHCP. Is that correct?

It does work, in general.
The problem is likely to be in the systemd configuration. Quoting
systemd.mount(5):
· Network mount units automatically acquire After= dependencies on
remote-fs-pre.target, network.target and network-online.target.
Towards the latter a Wants= unit is added as well.
Depending on which network configuration tools you use, you might need
to define additional dependencies for network-online.target or
remote-fs-pre.target.
