Unattended 5.3 install post-configuration problem.

[David Robillard]

Hello everyone,

I've setup an unattended automatic FreeBSD-5.3 install server. Clients
boot via PXE and receive the OS in around 15 minutes using a
sysinstall(8) script.

I need to perfom post-install configuration, so I wrote a
post_install.sh shell script which is called at the end of the
sysinstall(8) script.

My problem is that I can't get my post-install script to modify
rc.conf(5) because sysinstall(8) re-writes the file and removes 
my configurations (all lines from rc.conf(5) starts with `#REMOVE' ).

The sysinstall(8) man page only says:

This utility may edit the contents of /etc/rc.conf, /etc/hosts, and
     /etc/resolv.conf as necessary to reflect changes in the network
	configuration.

How can I prevent or circumvent this "feature" of sysinstall???

Any help would be really appreciated.

Here are the files:

# From sysinstall(8) install.cfg:
#
command=/stand/post_install.sh
system


# From /stand/post_install.sh
#
cat <<- "END" > /tmp/a
        # rc.conf
        #
        # Please make all changes to this file, not to
/etc/defaults/rc.conf.
        # This file now contains just the overrides from
/etc/defaults/rc.conf.
