With the recent removal of the toor account, it is appropriate to move
the root login-shell from csh to /bin/sh. Reasons for it are most
widespread base on all Unix systems and more intuitive command line
handling over csh.

After discussion with a few developers, I've committed this change. 
Please let us know if you have any troubles. :)
