The new concretizer does not respect hashes of installed packages in the spec. With the old concretizer, it was possible to reuse previously-installed packages by explicitly specifying the hash of the package. This is no longer possible with the new concretizer.
Steps to reproduce the issue
spack install B, keep track of the hash of this installation- Add a new variant to package B
spack install A ^B/hash for a package A that depends on B
Error Message
Here is an example with Python. Note that since the time Python was installed, the openssl dependency added a new ~docs variant:
$ spack find -lvd /3auqbnq
==> 1 installed package
