- Add "Two Packaging Patterns": pure OSS kmod subpackage vs. combined kmod+userspace
- Rework Naming and Versioning: stable subpackage name with driver version in Version and kernel NVR in Release, plus the %{version}/%{release} macro-restore needed so %{KVERREL} resolves correctly in Requires
- Document %{KVERREL}-keyed modprobe/license paths for per-kernel coexistence
- Add the kmod-nvidia-open-matched sentinel + boolean-Requires auto-upgrade mechanism and the problem it solves

| installation tracks the kernel automatically — but only when the admin has | ||
| opted in. Three pieces: |
