This page will detail how to have /tmp and /var/tmp run under a mounted RAMDISK /dev/ram0. This is done for several reasons. First, if /tmp and /var/tmp are mounted under root /, they can cause large amounts of disk fragmentation due to the creation/deletion of a large amount of files. Second there is a noticeable performance gain, especially when dealing with large programs, (ie, KDE, gnome, OpenOffice, Etc) that use /tmp and /var/tmp to store/interact with information. I would not recommend this process for systems with a small amounts of ram.

Tell the kernel to make the Ramdisk at boot
You will need to edit which ever boot loader menu you have {IE:grub, lilo} and add ramdisk_size=56000 to the kernel boot parameters. It should resemble the following. This tells the kernel to create a ramdisk 56Mb in size.

Edit your /etc/fstab and add /tmp /var/tmp
