I don't even care about that data surviving during a 'reboot' :)
and as such I'm using tempfs (you can use something else) to create
a ramdrive for /tmp or /xtmp.

mount -t tmpfs /dev/shm /tmp

And in theory, the numbers I've seen tend to show that this is a bit
faster than having /tmp in the vfs cache path. Though I'm not an 
expert on the topic. However, I have noticed that on our compile box
(since gcc tends to toss it's temp .o files in /tmp) it's a bit lighter
on the drive.

What is the general idea about /tmp?
Are there any hard rules?
