This allows us to chain our Spack environments to system Spack instances. See https://spack.readthedocs.io/en/latest/chain.html.
In July 2024, the nodes in the Cascade Lake partition were updated from CentOS 7 to Rocky Linux 8. They now share the same OS as other CPU partitions on CSD3 so they have been combined and the references to OS versions have been removed.
Following the upgrade of the Cascade Lake nodes to Rocky Linux 8, all CPU partitions can use the same software stack. We switch to using the software stack built for the Cascade Lake nodes as this is the newest and works on all partitions. Instead of adding system provided packages as externals, we instead chain our Spack environment to that of the system Spack instance.

In July 2024, the nodes in the Cascade Lake partition were updated from CentOS 7 to Rocky Linux 8. They now share the same OS as other CPU partitions on CSD3 so this combines all the partitions under one system again rather than having separate ones for different OSes.
We switch to using the latest available software stack which is that built for the Cascade Lakes. This works on all CPU partitions. Instead of adding system provided packages as externals, we instead chain our Spack environment to that of the system Spack instance.
This resolves #355.
