system_a partition file system

The system_a partition file system is a type of file system used in Android devices. This partition contains the core system files and applications that are required for the device to function properly. The file system used in this partition is generally the ext4 file system, which provides support for large files, journaling, and improved performance over previous file systems used in Android devices. The system_a partition is mounted as read-only during normal operation to prevent accidental modification of critical system files, but can be remounted as read-write by a privileged user for system updates or modifications.
