Alternate Shells

[Conor Rafferty]

A quickie: 4.2BSD chsh does not allow the user to specify alternative
shells - only "sh" and "csh" are permitted. Why is this? It seems
ironically inappropriate in UNIX, where the shell is ``an ordinary,
swappable user program'' and ``user-selectable system interfaces [...]
become essentially trivial to implement'' [Ritchie & Thompson CACM 1974].
