Hi ALL,
I have build an embedded Linux system and rootfs is a ramdisk. Ramdisk
rootfs resides in memory so modify files is non-effective after a
reboot. Some directories in rootfs, like /etc, /usr, ... are contain
many application configuration files and I want to mount it to jffs2
flash

Okay, I think the steps is below if my rootfs is ramdisk and configure
files in jffs2,
1. cp /etc/* /mnt/mtd/etc/(/mnt/mtd is my jffs2 fs)
2. rm -rf /etc/*
3. make symbolic links from all /etc/xx to /mnt/mtd/etc/xxx
4. remake ramdisk rootfs

them). other filesystems are more efficient in this aspect.

I consider to use ramdisk as rootfs because worry about wrong
operation in rootfs (is use jffs2 rootfs) and it will cause system
