Hi John!

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!
