the ahcp-config.sh should be updated to use uci states to set ip  
addresses, as right now, the settings will not survive any actions of  
luci/uci.

the initscript has already been updated to use symbolic interface  
names lik "lan" or "freifunk" instead of "eth0.2" or "ath0".

you also need to address uci sections out of the script, so something  
like
  section=`uci -P /var/state show network|grep ifname|grep $1$|cut - 
d . -f 2`
might help.

this is also very dirty and should be done in separate config variables.
