resolv.conf.save ??

[Tom Brown]

what creates this file as i am trying to manipulate my resolv.conf with 
a snippet but after a while looking into why it seemed to not be working 
it seems that changes get wiped out by whatever creates resolv.conf.save -

I am doing manipulation at the very end of the ks post so i would have 
thought all cobbler internal stuff would have finished by then ?

thanks
