That would make sense. The same thing happens if you use zebra (gated
replacement). The system does not behave very well if you don't add
manually about 20 sleep seconds in the rc script !

With dhclient, the problem is really not that bad. Within 3 seconds
you normally get the lease. Which means, that we could add a script
which checks, if the dhclient interface has a 0.0.0.0 adress (or even
check if the default route is set), and then sleeps and blocks the
boot process.  The applications which really need this could rely
then on the script. And all other setups without this would boot
faster.

Just some thoughts ...
