Because I am searching for the most easy and most flexible way for what I 
need.
If I want to change the static ipadress in the above mentioned example then I 
have to change the file (remountrw, change ipadress in file, remountro, and 
so on).
Isn't it possible to supress the execution of /sbin/dhclient (or a script) at 
boot time and execute it later from the application if required?
If there is no dhclient program then I am able to set the ipadress manually 
with ifconfig without changing config files if I am right. This works already 
with my application. Then I can use this part of the software in the future 
also.
