swap not mounted?

Actually it is mounted, since I can see it when using "free" command.

Swap: 538168 0 538168

But I can't see it when typing "mount"

Below is my /etc/fstab. Notice there isn't a "/" before swap. Swap don't need
to be a physical directory?

No it doesnt. If you see it when you do free it should be good. You can also check with "top".

Nope it doesn't. A typical swap entry in /etc/fstab would look like that :

Issuing

Code:

cat /proc/swaps

informs you about your swap file physical location and its priority.

Yea having swap mounted would be very bad. Think of swap as just a stick of memory. If you were to be able to go into a stick of memory your kernel is using and just start sticking crap in there or removing stuff your kernel would not be too happy ;).
