One thing that I really like in Buildroot is that by default, it
generates you a system that boots really fast. People often don't have
to do anything special with Buildroot to make it boot fast. So having a
shell script that is installed by default and does a "sleep 1" in a
loop is not very nice :-/
Though I agree that it will only slow the boot on systems where the
network interfaces are not available immediately at boot time.
