inside the file system design, and support for hard links.
The key features of JFFS2 are:
y Targets the Flash ROM Directly
y Robustness
y Consistency across power failures
y No integrity scan (fsck) is required at boot time after normal or abnormal shutdown
y Explicit wear leveling
y Transparent compression
Although JFFS2 is a journaling file system, this does not preclude the loss of data. The file system
will remain in a consistent state across power failures and will always be mountable. However, if
the board is powered down during a write then the incomplete write will be rolled back on the next
boot, but writes that have already been completed will not be affected.
