The kernel will enter an infinite loop to keep it running.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmalwarebo%2Fkernel","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmalwarebo%2Fkernel","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmalwarebo%2Fkernel/lists"}
