correct_password: This code seems to alter the busybox code to check passwords in plain text rather than using the pw_ecncrypt options. Like, why? Anyway, we have ssh working and telnet working as far as we can tell, so I think we'll lose this Netgear feature. If someone finds a reason to re-=instate it, let's create an issue to change things so that we don't need plain text passwords!

askpass: This line is added so that if you enter a blank password, it asks again. But only once. Losing these lines are a good thing.
