This issue qualified for the following of the Final Freeze mail:
I'll be adding a SRU Template to make things clear.

2) Bug fixes that would be suitable for post-release SRUs, which we
   may choose to accept, reject, or shunt to -updates for 0-day SRUs
   on a case-by-base basis.

** Description changed:

- Upon a MAAS reboot openstack nova-compute services come up blocked with
- the following message in juju status:
+ [Impact]
+ 
+  * Since the Zesty Merge the qemu-kvm service fails to be active by 
+    default.
+ 
+  * It is a non required but rather useful helper, so it should be fixed to 
+    be enabled as it was pre zesty due to systemd-generators taking it from 
+    sysv scripts back then.
+ 
+ [Test Case]
+ 
+  * Install qemu-system-common
+  * Then check
+    $ systemctl status qemu-kvm
+  * This should be active (exited) but is currently disabled
+ 
+ [Regression Potential]
+ 
+  * If this script causes any issue for someone (not known so far) and he 
+    was running on zesty a while it will on the SRU update be enabled and 
+    trigger these issues. Yet this is a generic argument and if that would 
+    be a blocker no services would be allowed to be enabled. I verified 
+    that if masked the service stays off as it should.
+ 
+ [Other Info]
+  
+  * IMO this issue qualified for  (2) the following of the Final Freeze:
+    2) Bug fixes that would be suitable for post-release SRUs, which we
+    may choose to accept, reject, or shunt to -updates for 0-day SRUs
