- Compatibility: Firmware images are tightly coupled to hardware platform IDs and feature sets. Installing an image built for the wrong platform can brick a device or disable features.
- Licensing and features: Tokens like "k9" historically signal inclusion of cryptography or enterprise features that may be subject to export controls or license checks; "exclusive" variants may contain additional licensed capabilities.
- Boot behavior: Identifiers like "mz" reflect how the image is loaded; using the wrong format can prevent proper booting.
- Supportability: Vendors support specific image-platform combinations. Using an unsupported image can void warranties or complicate troubleshooting.
