Massimiliano Culpo 4d7e7f25c4 Fix installing specs from yaml file (#6906) ... The feature added in #4611 is currently broken. This commit fixes the behavior of the command and adds unit tests to ensure the basic semantic is maintained. It also changes slightly the behavior of Spec.concretized to avoid copying caches before the concretization (as this may result in a wrong hash computation for the DAG).		2018-01-16 08:03:10 -06:00
