changing the root's shell

Hi ! Ouch ! SuSE 9.1 is quite different from a standard linux, isn't ? How can I change the root's shell from bash to tcsh ? I edited the file /etc/passwd, but the subsequent login as root, still have bash as shell. This is quite amazing ! Has SuSE tweaked the /bin/login ? any ideas ? I really like tcsh and I already have a whole bunch of files (.tcshrc*) setup for root. regards,
