And if the daemon sets the address after you test it but before
you try to set it in the script, what happens?

This is why I hate changes like this.  They don't remove the problem,
they make it smaller.  And smaller in a bad way.  Smaller makes the
problem even more harder to diagnose when it happens.

There is implicitly no synchonization between network configuration
daemons and things people run by hand like this script.

So, caveat emptor.

I'm not applying this, sorry.
