I'm trying to make some permanent changes to /etc/network/interfaces but it resets on reboot. A general search brought me to

http://webcache.googleusercontent.co...trip=1&vwsrc=0

which suggests that a startup script is rewriting the file each time on booting. The solution on the page is for Debian and the startup script named there is /usr/sbin/debian which doesn't exist on my Kali install version 2016.1 32bit.

Does anyone know where the equilvalent script for Kali should be? Or know of another way to solve the problem? Thanks!
