I have plain DHCP and don't use background_dhclient too. I wonder why 
somebody have not see it. Look at this lines from v1.28:

background_dhclient=`get_if_var $ifn background_dhclient_IF $background_dhclient`
        if checkyesno background_dhclient; then

Since background_dhclient_fxp0="" automatically set earlier, 
background_dhclient evaluates to "" too.
Then checkyesno background_dhclient produces this warning.
