I make a habit of sometimes booting with the wireless card in and
sometimes plugging it in at some time when I need the internet access.
It makes no differance, the blacklisting works.
So now I wonder why yours does not. That is why a premission and
ownership check I mentioned.
I am not that far along on hotplug, perhaps someone else can chime in.
When I want to look for "the involved files" in Linux I use:
The man pages (usually located near the bottom of the page - also the
other commands mentioned in the page).
The "locate" command after running a fresh "updatedb" as root. Locate
works well with grep of course.
One day I do hope to conquer hotplug and all.
Have a great week!
