Ask HN: Any kernel/OS vendors?

There must be companies which maintain their own OS but do only minor changes which doesn't justify keeping proper kernel/OS team. Other than RedHat, SuSE and Canonical (which are quite costly), are there any other players which provide kernel/OS development/maintenance/packaging etc? Do companies even need such services anymore?
