Telcon: 2022 07 20

Attendees

• Peter Scheibel (host)
• Massimiliano Culpo
• Phil Regier
• Mark Krentel

Agenda items

• Discussion: should packages.yaml preferences be prioritized above reuse?
  • https://github.com/spack/spack/pull/27987 should be updated to mention the schema in the PR description
  • Peter: @Mark I want to make sure that your specific interest is to use priorities (if you are frustrated when a request isn't respected, then perhaps a requirement is in fact the easiest approach)
  • Max: If we have requirements, do we still need preferences?
    • Mark: yes:
• Mark Krentel: we should add https://github.com/spack/spack/discussions/31525 to the README and other pointers
