passwd from stdin

[Cathey, Jim]

It is also not uncommon for a rescue disk to
only allow the removal of passwords.  You then
get in with the system running normally and
recreate them.  That can be done with sed,
etc.  Once you're in as root, that is.

Thanks for the reply, but this is not going to help me, and I am still 
searching for the solution. I will explain You my exact requirement, so
that 
You can understand it better.
I am creating a Rescue mode option for "DeepOfix Mail Server" 
http://code.deeproot.in/deepofix . Now, when the user enters rescue
mode, I 
want to create a ncurses/dialog screen in which he can change the
password of 
that system. Now since the system is in Rescue mode, It lands in the
rootfs 
environment, which is the below link 
http://code.deeproot.in/deepofix/browser/trunk/var/rootfs
 It has a very minimal environment, and It runs only busy box commands.
Now, I 
cannot use the crypt file, which You have attached, as python is not 
installed in that. Even, the useradd script cannot be used as it will
not 
create the encrypted password to save them in the /etc/passwd file. 

I tried my best to explain my requirement. Can some one please suggest
the 
solution for this.
