    Quote from http://www.omgubuntu.co.uk/2010/11/move-google-chrome-cache-to-ramdisk/:

    gksu gedit /etc/fstab

    Add the following line to the bottom of the text file that opens but BE CAREFUL – do not touch, edit or enter ANYTHING else:

    tmpfs  /media/ramdisk  tmpfs   defaults,noatime,mode=1777 0 0

  2. I don't quite know what you mean with a RAM drive but if you mean more swapspace, you'll have to use a livecd with gparted, add a new swap partition, and then edit /etc/fstab to make the swap partition mount on boot.

    Be careful, though, since making a mistake while editing fstab could have disastrous results and your system may not boot up anymore.

    Also, you can mount two partitions under the same name, like swap.
