*DOH* (homer style)

yes! i forgot to add http:// and ftp:// to the variables >.<*
this works wonderfully with squid: http://paste.pocoo.org/show/216945/

now i only wonder what would be the best way and place to save these
variables in the installed system ? in worker_configure_system() in
the users aif profile ? but where should i write them on the installed
system ? and can i restrict it only to pacman ? (for general proxy
like squid. pacproxy.py would be only used by pacman, hence my main
interest on it)

1000x thanks for the tips!
