Weitere Hintergründe und Informationen rund um Entwicklungen im Linux-Kernel und dessen Umfeld finden sich in den vorangegangenen Kernel-Logs auf heise open. Neue Ausgaben des Kernel-Logs werden auf den Identi.ca- und Twitter-Konten "@kernellog" erwähnt; die englischen, bei den Kollegen von "The H" erscheinenden Übersetzungen auf den Identi.ca- und Twitter-Konten "@kernellog2". Gelegentlich zwitschert der Autor des Kernel-Logs unabhängig davon über einige Kernel-Log-Themen bei Identi.ca und Twitter als "@kernellogauthor". (thl).
