So if I want set etc directoyr to /dev/mtd5 not in rootfs /, I need to add "/dev/mtdblock5 /etc jffs2 defaults 0 0" in /etc/fstab file but rootfs doesn't contain /etc directory because /etc directoyr is store in /dev/mtdblock5. Do you know what I mean? The kernel execute /sbin/init after mount rootfs and /sbin/init is link to busybox, busybox will read /etc/inittab file to initial. The problem is coming, how busybox to read /etc in rootfs before mount /dev/mtdblock5 to /etc? There is no program to mount /dev/mtdblock5 to /etc before busybox init execute. I think I must mistake some concept, please give me a hint. Thank you BRs, H.
