Re: different nwkeys for wifi

[Gregor Best]

I use a simple AWK script which parses the available networks as
returned by ifconfig wpi0 scan and selects the first known one it finds.
It then creates an /etc/hostname.wpi0 for that network and runs
/etc/netstart wpi0. I attached it for reference, though I think it's
extremely easy to rebuild from scratch.
