NixOS #148 (14 Mar)
Automatic discovery of wireless interfaces broken in 3.3.0-rc7 due to sysfs change
Using linuxPackages_3_3, nixos/modules/services/networking/wpa_supplicant.nix's generated upstart script fails to autodetect the wireless interfaces, since there is no wireless file in the expected sysfs place, leading to a wpa_supplicant command line that does nothing. (But executes without any errors, surprisingly.)
script =
''
${if ifaces == [] then ''
for i in $(cd /sys/class/net && echo *); do
if [ -e /sys/class/net/$i/wireless ]; then # <----- here
ifaces="$ifaces''${ifaces:+ -N} -i$i"
fi
done
'' else ''
ifaces="${concatStringsSep " -N " (map (i: "-i${i}") ifaces)}"
''}
exec wpa_supplicant -s -u -c ${configFile} $ifaces
'';

I also have
hardware.firmware = [ pkgs.iwlwifi3945ucode ];
set in configuration.nix since I thought I had to. I suspect the phy80211 could be used instead of wireless, but I am not at all sure. A quick and easy workaround is to be explicit, i.e. set
networking.wireless.interfaces = [ "wlan0" ];
in configuration.nix.
