Because even allegedly compatible shells differ subtly, you run
the risk of having a key startup script fail - and maybe not right
away, but after installing an update.
Better to create a second user (FreeBSD uses toor) with uid=gid=0 but
other login shell.
I used to do this, preferring ksh over csh, but now rarely bother,
using sudo instead to do most root ops.
