I don’t like missing 3D GPU drivers, and missing .NET runtime. If it had these two things I would try OpenBSD for embedded use cases, instead of Debian or Alpine Linux.
Linux GPU story is not stellar but for embedded applications it’s not too bad; KMS, DRM, and GL or GLES library stack worked amazingly well for me.
