The inadvertent interface name change was fixed in https://github.com/systemd/systemd/commit/8eebb6a9e5.
Version-Release number of selected component (if applicable):
Proposed as a Freeze Exception for 28-beta by Fedora user zbyszek using the blocker tracking app because:
This can potentially break networking. And if machines are set up with this bug present, and then systemd is upgraded to a version without this bug, the interface names will change again. All in all, it's better to fix this as quickly as possible.
+1 FE for me.
systemd-238-5.fc28 has been submitted as an update to Fedora 28. https://bodhi.fedoraproject.org/updates/FEDORA-2018-037a145d4d
Discussed during the 2018-03-26 blocker review meeting: 
The decision to classify this bug as an AcceptedFreezeException was made as this could break many network configurations on upgrade, and upgrades use the stable repositories (not updates-testing), so we should get this fixed in stable ASAP.
systemd-238-5.fc28 has been pushed to the Fedora 28 testing repository. If problems still persist, please make note of it in this bug report.

The fix for this was pulled into the Beta-1.1 (Beta RC1) compose. Can anyone with an affected system confirm the fix in that compose? Thanks.
Let's close this, since no feedback is apparently coming.
