Create a custom package that adds data to /etc/rc.conf during installation using pkg-install. Watch how rc.conf is emptied on install clients after throdes' changes to config.c: root@neta:~# cat /etc/rc.conf # -- sysinstall generated deltas -- # Mon Nov 3 07:09:40 2003 # Created: Mon Nov 3 07:09:40 2003 # Enable network daemons for user convenience. # 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. hostname="booter" ifconfig_fxp0="DHCP" root@neta:~# Proof of concept: make that custom package add data to a temporary rc.conf file instead, and of course, it is not emptied. >Fix: Re-do patch 1.156.2.34 -> 1.156.2.35 in src/release/sysinstall/config.c (RELENG_4) and 1.210 -> 1.211 in src/usr.sbin/sysinstall/config.c (HEAD). Work-around for your custom PXE post-installation fixup/rc.conf modification package: a) Create a temporary rc.conf script. b) Create a /usr/local/etc/rc.d script that adds the contents of your temporary rc.conf to the real one upon the next reboot, deletes itself and then does another reboot. >Release-Note: >Audit-Trail: >Unformatted:
