filesystems - Advantage of using jffs2 for kernel and initramFS in NAND -

In our system, we use jffs2 to write cursors and initramfs in nand memory, we will soon use strong ECC But the new ECC format requires the entire OOB area, and does not work with JFFS 2.

I still can not believe why we need to use JFFS 2. AFAIK kernel and initramfs are copied to RAM on startup, and runs with RAM. They have not changed many times (possibly many times a year for updates)

jffs2 of flash memory For files created as a file system, commonly used as a rootfix, it is no use for the kernel and initramfs image.
