Google is planning on including the Enhanced Read-Only File System (EROFS) in Android 13, making it the default read-only system. The file system was created by Xiang Gao when he was working as an engineer at Huawei. EROFS offers significant benefits over existing file systems, including space-saving compression and speed. This could lead to much faster updates and less storage space being used.Huawei developed EROFS for inclusion in the Linux kernel, which forms the basis of Android. Despite eventually being locked out of the Android ecosystem by US-led sanctions, the file system officially became part of the Linux kernel, beginning with Linux 5.4. It has also been used on millions of Huawei devices and is being adopted by other manufacturers.Google now plans to make it the default file system for read-only partitions, such as those used by the core Android system.
