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 It seems all files in ramdisk rootfs /etc all links to /mnt/mtd/etc/ and try to modify these files is effective after reboot. But is this a common way in embedded linux ?
In principle, but it is easier (and cleaner) to make a symbolic link from (say) /etc -> /mnt/mtd/etc without linking every individual file and directory.
You could also use a jffs2 file system in flash for your rootfs, that way you wouldn't need a ramdisk at all.
