Flatcar Container Linux retweeted
4th time's the charm. 🚀 After 3 terms of LFX rejections, I officially got selected for the LFX Mentorship (2026 Term 3)! I’ll be contributing to @flatcar Container Linux, building a Cloud-Init to Butane YAML config transpiler. Also special thanks to my mentor tormath1.
