3# Provides a facility to hook into rfkill changes.
4#
5# Exemplary usage:
6#
7# Add this package to udev.packages, e.g.:
8# udev.packages = [ pkgs.rfkill_udev ];
9#
10# Add a hook script in the managed etc directory, e.g.:
11# etc = [
12# { source = pkgs.writeScript "rtfkill.hook" ''
13# #!/bin/sh
14#
15# if [ "$RFKILL_STATE" -eq "1" ]; then
16# exec ${config.system.build.upstart}/sbin/initctl emit -n antenna-on
17# else
18# exec ${config.system.build.upstart}/sbin/initctl emit -n antenna-off
19# fi
20# '';
21# target = "rfkill.hook";
22# }

24# Note: this package does not need the binaries
25# in the rfkill package.
