The last step is to modify the startup scripts that run zspconfig to use the -coption. The -coption allows you to provide a dhclient.conf script rather then having zspconfig create a default. For example, the S60SP_startup script line that reads:

echo y n zspconfig -t 10 -su zhp0 > /dev/null 2>&1

Can be modified to

echo y n zspconfig -c

/etc/rcZ.d/surviving_partner/dhclient.new.conf -t 10 -su zhp0 > /dev/null 2>&1

If you use S60SP_startup, the /etc/rcZ.d/surviving_partner/zsp.primary.conf file should not exist. This way the S60SP_startup script will first look at the Central Authority. If the Central Authority is down, then it will use its current configuration.
