Client
Isn't it possible to make it easier?

Is it possible to let /etc/network/interfaces untouched?

To supress the start of the dhclient program in general?

And then later (if required) start the dhclient program?
Or set (if required) the ipadress manually with sudo ifconfig 
eth0 192.168.178.10 for example.

That worked fine in the past with the previous dhclient 'pump' in earlier 
voyage distributions.

I need to know where in the startup script the dhclient program ist started.

There are 2 files which are likely involved here:
/sbin/dhclient
/sbin/dhclient-script

But I am not sure where to begin.
