I'de some questions about /tmp directory:
My /tmp directory permissions are:
rwxrwxrwt 2 root root 1024 Sep 13 14:17 tmp
... meanwhile chmod manual says that "t" permission is to: save program
text on swap device !
What this means !? /tmp directory isn't on any swap device !
It's a "good policy" for /tmp directory to have 777 permissions !?
With such permissions any user could write on that directory until even
there's no more space on device, rigth !?
