changing the default shell

[LeVA <leva@az.isten.hu>]

Hi!

I wish to change the default shell on my debian system. I want this 
change to affect all current and all future users.

I guess this is a simple job, because I just have to install the new 
shell, add it's binary's name to the /etc/shells file, and execute chsh 
@USERS. So much for the current users.

But in both of the /etc/defaults/useradd and /etc/adduser.conf files 
there is a variable called (D)SHELL. Those points to /bin/sh. Is it 
safe (future-proof) to change the /bin/sh symlink so it won't point to 
bash but my new shell. Will this change break some packages or upgrades 
or my new coffe mug?

Thanks!

Daniel
