You are aware of ifplugd (and libdaemon0 on which it depends) originate,
right? I guess I just had a knee-jerk reaction to that, similar to the
way people on this list have something against pulseaudio :-)

$ apt-cache show ifplugd libdaemon0 | grep Homepage:
Homepage: http://0pointer.de/lennart/projects/ifplugd/
Homepage: http://0pointer.de/lennart/projects/libdaemon/

Anyway, if ifplugd works for you that's fine. For me, netplug does the
job and didn't need any configuration. It worked out of the box.

I used wpa_gui on one occasion and rolled a wpa_supplicant.conf for
roaming purposes by hand following the manual page and examples. Not
exactly user friendly but not rocket science either.

I'm not using the GROUP variable on my home laptop (nor do I have the
`DIR=` bit in there). I am member of the netdev and plugdev groups. I
believe that takes care of things for me.

I also don't have update_config set in my /etc/wpa_supplicant/conf.d/
snippets.
# Eh, yes, I don't have a wpa_supplicant.conf file. I wrote snippets
# for each of the places where I need things to work.

At the office I use a wpa-roam.conf. See the example file for more info
on setting this up.

Hope this helps,
