Redis modules (.so) in redis:latest are not included in Syft SBOM

Hello,

I was analyzing SBOM completeness for container images using Syft and noticed that Redis modules present in the redis:latest image are not included in the generated SBOM.

Inside the container, the following Redis modules exist:

/usr/local/lib/redis/modules/

Files:

- redisbloom.so
- redisearch.so
- redistimeseries.so
- rejson.so

I verified this by running:

docker run -it redis:latest bash
ls /usr/local/lib/redis/modules/

However, when generating an SBOM using Syft, these modules do not appear in the component list.

Example commands:

syft redis:latest -o table | grep redis

Output:

redis 8.6.1 binary

CycloneDX output:

syft redis:latest -o cyclonedx-json | jq '.components[].name' | grep redis

Output:

"redis"
"/usr/local/bin/redis-server"

The Redis modules are not included in the SBOM.

Environment:

Syft version: 1.42.2
Image: redis:latest

Question:

Is this expected behavior because these modules are standalone shared libraries (.so) that are not associated with a package manager?

Or would it be useful for Syft to detect such modules as components in the SBOM?

Thanks for your work on Syft!

Reproduce the report with `docker run -it redis:latest bash`, inspect `/usr/local/lib/redis/modules/`, and compare it with Syft's table and CycloneDX output. Determine whether standalone `.so` modules should be represented as components; done means the expected behavior is established and, if inclusion is intended, the modules appear in the component list.
