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=20
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=3D/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.
