in this case, i can't seen any point in providing pw_passwd since no program that uses it (for anything non-trivial) could work on Plan 9. in fact, it's not even useful on unix systems:
When shadow(5) passwords are enabled (which is default on many GNU/Linux installations) the content of pw_passwd is usually not very useful. [because the contents are hidden in another file] so: the program that refers to it won't be ported to plan 9, and probably won't work on unix. best just to fix it by removing the reference.

It's an interesting philosophy, but it just bites you in a different spot :-) That said, it's obvious from the way the question was posed that there is no single answer. ++L
