Preferably, that\ninterface would be able to implement `posix_spawn()`.\nLi Chen, the author of the spawn-template work, has now responded with [a patch series](https://lwn.net/ml/all/cover.1784204592.git.me@linux.beauty)\n(written with significant LLM assistance) showing what a process-builder\nAPI for Linux might look like.", "url": "https://wpnews.pro/news/the-beginning-of-a-process-builder-api", "canonical_source": "https://lwn.net/Articles/1086330/", "published_at": "2026-08-04 13:27:51+00:00", "updated_at": "2026-08-04 13:44:55.068160+00:00", "lang": "en", "topics": ["developer-tools"], "entities": ["Li Chen", "Linux"], "alternates": {"html": "https://wpnews.pro/news/the-beginning-of-a-process-builder-api", "markdown": "https://wpnews.pro/news/the-beginning-of-a-process-builder-api.md", "text": "https://wpnews.pro/news/the-beginning-of-a-process-builder-api.txt", "jsonld": "https://wpnews.pro/news/the-beginning-of-a-process-builder-api.jsonld"}}
