This has been noted. Also we have similar reports that ubuntu starts degraded in containers by default on all arches in artful at the moment.

This is seen on s390x, because unlike other arches, the ADT tests use container confinement instead of kvm confinement.

Actions to take:
1) make all kvm arches execute the tests twice, with VM and nested container confinement
2) fix degraded boots in containers

This particular regression, at the moment, is not considered to be architecture specific.
