Except that getpwent() etc have got hard coded references to yp, and yp has
got hard coded references to getXXXbyYYY(), which has references to
libresolv. The number of things that are infected by this is quite big.
This means a good number of things in /bin and /sbin would have to have
-lresolv added. And that defeats the point. All that we do is move
the bloat from one library to another.
It's the same problem with the db embedded in there - getpwent() uses
it via the pwd.db stuff. And then there's the cgetent() stuff that
that *curses uses to access termcap.db. And login.conf.db. And so on.

Except to satisfy internal dependencies.
