Bad example. B-)

The problem with things like ls(1) is more complex. Once you start
dealing with user names, you have to pull in all of DB, which is huge,
plus the rest of nsswitch stuff, which BTW includes YP and RPC, and the
message catalog system, and...
This stuff should be in separate, dynamically loaded, libraries. You
use getpwman(3), it loads libnsswitch_db.so, which loads libdb.so, and
goes from there. Or loads libnsswitch_yp.so, and that pulls in
librpc.so. None of this crap should be in libc in the first place.
