As part of the datacenter migration, the rhel7 and rhel8 variants are now pointing at newer versions of the respective platforms than intended. For example, the rhel83 s390x build is now actually building on rhel89. This ticket tracks the work necessary to point them at the proper variant (rhel83 -> rhel83. There should be no downstream impact or needed changes as a result of this.
We have poc patches for how this might look but the actual structure and naming is up to Build to decide.
rhel8.3 6.0: https://spruce.mongodb.com/version/6717f189c5d6bc00073c3eac/tasks?sorts=STATUS%3AASC%3BBASE_STATUS%3ADESC
