We're running 4.1bsd on some VAXen here.  Recently I've been pondering
the pros and cons of changing "init" to use /bin/csh as the single-user
and /etc/rc shell.  Can anyone out there think of a good reason why I
would not want to do this?

My motivation is basically that /bin/csh seems so much better than /bin/sh.
