I just found one thing:
Even when boot from CF, the system still use /mnt/settings on iLiad, not /mnt/settings on cf. That's to say, every modification made to /mnt/settings on cf won't take effect.

Added:
This problem should be fixed if I edit "/etc/fstab" and remark the line with "/mnt/settings". Then system boot from cf won't mount /dev/tffsa7 on /mnt/settings, and /mnt/settings on cf will be used.
