Is there, then, a way to empty /tmp and swap everytime I shutdown?
You could create a symlink from /tmp to /dev/shm. This means that your /tmp will be on a RAM disk.
I would not recommend this. Some programs write sizeable files to /tmp.
And also means that my RAM will be hogged for this purpose, yes?
As for swap, you'd have to write junk to the partition on shut down.
How?
Just copy /dev/null to the swap area.
Who are you defending your data from?
Data recovery experts are able to undo several writes to a disk, which is why wipe disk programs do several passes, and agencies that are concerned about loss of data grind up the disk afterwards rather than take the chance that someone may have improved the technique to read wiped data.
There have also been rumors that they can read data from old ram, and the EM leaking from your screen can be read from across the street.
Sorry, that should be "from 200 metres away" by someone sitting in a van and not just "across the street". Cheers. -- Light travels faster than sound. This is why some people appear bright until you hear them speak.
