Modifying rc.conf postinstall

[Nora Lavelle]

I'm new to FreeBSD and am trying to implement a kickstart environment. I
have everything working except I want to modify the /etc/rc.conf
postinstall. Each time I do after the reboot the rc.conf settings go
back to the original settings and the new settings end up at the top
with a #REMOVED before them. Is there a way to modify the rc.conf
postinstall ? 

 

I'm using 6.1. 

 

Thanks in advance !
