Spack Environment Concretization Duplicating Dependencies #11095
Description
We are investigating spack environments as a way to replicate build environments and noticed top level dependencies being built as separate variants.
Is this expected behavior or should the concretization process be spread across all specs in the spack.yaml?
Steps to reproduce the issue
Reproduced on multiple platforms and verified in the spack/ubuntu:18.04 container with commit 7a28a61
[ubuntu] tmp2: cat spack.yaml
