[Sussex] Why Linux doesn't need defrag

[Desmond Armstrong]

1/ The Linux uses swap file so that things are written cleanly at the 
end of session.
2/ Every 50 times or so of booting full checks are forced.

So for the normal user there is no defragging file checking or anything 
to worry about. The system simply works without fuss and with astounding 
reliability, now just why can't I have a virus to join the Windows crowd 
who do so enjoy them!?
