We aren't going to be using NSS in that way... we will be using IPC
services for such lookups. But if you need a getpwnam_r() it should
be possible to adapt the existing getpwnam() (and other functions) in

Sure... I should look at this sometime :)

What I would do is rename, e.g., getpwnam() to getpwnam_r(), add the
required passwd pointer, and use the pointer instead of the static
_pw_passwd. Then write a new getpwnam() which simply aclls
getpwnam_r() using &_pw_passwd for the passwd pointer.

Yeah... that's pretty much what I was thinking about doing in FBSD... but it
was harder than it looked :)

Would you like to have a go at making this change? If you know any C
at all it should be a breeze. If not, maybe one of the other developers
would like to have a go at it. If not that, then I can do it (it would
take me less then 30 minutes to do).

I'd love to do it...
