Comment 9 for bug 352118

Hummmm... Until Wireless Just Works (which has never been my experience, even with F/OSS drives and Intel cards), turning off *all* wpa_supplicant logging to syslog sounds like a really bad idea. I do a 'tail -f /var/log/syslog' when attempting to get wireless cards working all the time, and no logging would be a problem.

It's just the useless logging that we're talking about here. And maybe that's what you are talking about with -s, but that isn't clear.
