@adinn I think there is some issue with s390x. With current changes I got build failure: 


Error occurred during initialization of boot layer

Though I don't see any command it ran before running into this failure. 

without your commits, i.e. on commit `235973615fbad7073df67167ab1cb4d40b6f1ab5` build is fine.
