https://issues.redhat.com/browse/RHEL-2120
a) We can't rely on .migrated file existence #3618 b) There could be artifacts left by host rpm used by mock which lead to broken files in mock's buildroot. (It could be solved by mock's bootstrap mode, but it is unnecessarily slow for this usecase)
.migrated
