- this is self-explanatory, the typo prevented the script from running,
this script is needed to reconfigure the default network system,
basically swapping eth0 and eth1, so that eth0 is wan and eth1 is lan.
This means that if there is only one ethernet interface, it doesn't
assign it a fixed IP address and start responding to DHCP requests on
it. It was broken for a long time but I didn't have time to investigate
until now.
