fair enough - can i ask then what is the intended purpose of 
"--profile=PROFILE cobbler profile to install" as that would do exactly 
as i want but as you state it does not handle the IP issues i have

for me dhcp in production is not really an option. i can get away with 
it for bare metal but alas not for rebuilds

thanks for your advice regarding this issue - i'll see what i can come
