Many embedded systems require writing to persistent storage during routine operation. While the journaling filesystems used on EMAC OE systems are tolerant of power failures during a write to the filesystem, it is still advantages to leave the root filesystem mounted read-only as often as possible to prevent any possibility of data loss or corruption on the root filesystem. One method to accomplish this is using a separate disk (such as an SD card) or secondary partitions on the primary storage device for any application-specific data that needs to be written to disk. This article describes the process of creating and utilizing an additional partition for data storage.
