I don't really know whether that's safe. There was a long discussion about
this recently and it was not about root being left shellless if /usr doesn't
mount (in single user mode the default is sh anyway). There was a specific
problem in the ports list that was tracked down to the someone not using a
shell in /bin (and copying another shell to /bin is just as bad, unless it's
statically linked). I didn't follow it in any detail - I decided it was
just better to stick to tcsh for root.
