http://forums.opensuse.org – In the process of reading a post by caf4926 I found out about Local Security Settings in Yast. It's accessed like so Yast>Security & users>Local security. One setting I found was under Miscellaneous settings click that & you get a box that allows 3 settings from a drop down: 1.Easy(default) 2.Secure 3.Paranoid I set mine to secure then I couldn't get access to any USBs! So I put it back to easy. What about you guys? (Distributions)
