The python script in wifi-radar-1.9.8-r1 doesn't utilize the configuration script /etc/wifi-radar/wifi-radar.conf installed by the ebuild (and described in the man pages). It generates a file /etc/wifi-radar.conf instead.

Created attachment 165231 [details, diff] The corresponding patch.
I would prefer get wifi-radar.conf in /etc instead of creating a subdir simply for placing one file, it would only require to patch manpage like debian is doing already: http://patch-tracking.debian.net/patch/series/view/wifi-radar/1.9.9-1.1/manpage.patch
(In reply to comment #3) Thanks for the hint. I had the same aversion for the subdirectory, but the original ebuild was written this way.
Created attachment 174907 [details, diff] Debian patch for the manpage As the patch applies without a problem, go for it.
Created attachment 174910 [details, diff] Patch for an improved ebuild Note: This should hold for v1.9.9 too, since the ebuild seems to be unchanged (check it please).
I'll fix bug #249842 instead, as that is the correct location for non-multiple package config files.
