Error after boot mango yellow

for example, I changed the file /etc/init.d/dropbear.wrappper and every time when I install a new firmware, this file does not change for me, but now I found the file in mnt/flash/etc/dropbear.wrapper Sothe system sees the file mnt/flash/etc/dropbear.wrapper and ignores it from the directory /etc/init.d/dropbear.wrappper, is it true?
