The ethernet interfaces were not renamed at boot, and left as eth0-eth9. 
During boot, systemd actually reported those names (eth0-eth9) when 
configuring networking.
I renamed the interfaces manually using ifrename after boot in order to 
be able to use the machine -- in production right now

ISTM that this is related to #794969, though evidently not the same.
Just upgraded to 228-2 from stretch; Will reboot in the next available 
window to see if this fixes the issue.
   ... would need a backpatch to Jessie or backport in that case, I guess :S

Has happened with three out of three machines upgraded from wheezy *and* 
using custom eth interface names.
Regular eth* interfaces (i.e. not renamed from the standard pattern) 
seem to not be affected.


Thank you, Michael.
