[opensuse] RE: Changing Global File Security

Open Yast>Security>Local Security>Custom>set file permissions to "secure" Can anyone please have a look at behind yast2 and tell me what is the impact of this action and when is it executed. This may solve up to 3 Major Bug issues I have Open but without making a fool out of myself I need to know what it does. Also is its action reversible by opening the same app. about 24 hours later and setting back to easy???? I am guessing it is a cron job but once executed cannot be undone???????/ Scott
