modifying nfsroot

[Mate Kosor]

Hi!

During some period of using FAI I run into problems when needed to have
things on nfsroot which fai-setup didn't put there. As I understand, if I
want to edit things here sources must be edited. If I just copy things I
need, these files will be erased on the following run fai-setup.

Example is this: no DNS server on network, clients during fai instalation
do not know about others unless valid /etc/hosts file is put into nfsroot
which is the thing I would like to be able to configure.

Are things in /etc/fai.conf only that help me configure nfsroot?
