Jan, is this a known issue that was fixed? The Doc Text looks like an enhancement. It is part of the erratum description at the moment: https://errata.devel.redhat.com/errata/details/24502 If it really is a known issue still, I'll add it to the Known Issues in the Release Notes here: https://access.qa.redhat.com/documentation/en/red-hat-enterprise-linux-atomic-host/7/single/release-notes/#known_issues
It is known issue and enhancement at the same time. However, as it already affects current customers and in some cases make the etcd unusable, it more classifies as known issue.
