I change root's shell to /usr/pkg/bin/tcsh on my machines, but I set the
password for toor (Bourne-again Superuser), in case I need to login with
/bin/sh. I've only needed to do that once though, and I don't remember
why anymore... maybe I accidentally deleted tcsh or something :)

If your /usr partition was totally screwed up, you couldn't even get to
multiuser mode and the login prompt; getty is in /usr/libexec. If you have
a buggy libc.so that makes all dynamically linked programs dump core, you
won't be able to run multiuser either (getty's dynamically linked). So
having root's shell on /usr seems pretty safe to me, especially if you
have toor's account set up. I suppose someone concerned about security
might want to have root's shell on / and mount / read-only or something...
