Initial Comment:
The bash completion for "chsh -s" uses the contents of /etc/shells as the list of posible completions. This makes sense for normal users, as their choice is usually restricted to one of these shells. However, there is no such restriction for root. In fact, on many systems there are binaries like /sbin/nologin or similar which are unsuitable as a login shell for normal users, but which are likely to be chosen by root as the login shell for special system accounts.

I therefore suggest that the completion for "chsh -s" detect whether it's run by UID 0, and if so, use normal path completin instead of using the contents from /etc/shells.
