Saying "you should > all change, because we made up a new syntax" is not good policy. Perhaps it would be good to at least fix the buggy bits of ifconfig and perhaps make it work with netlink instead of parsing /proc. Maybe not add features, but at least fix the broken bits and make it use modern interfaces. The interface to the user can stay. And of course if it happens to encounter a really old kernel, it should still remember how to speak to it with the old interface. > The people who did "ip" could have fairly easily have done a wrapper > around the same code that also left the old "ifconfig" syntax.
