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

It looks like the source was deleted / moved. But all the important stuff is written in the post above :) – Praweł Jan 12 '11 at 08:30

Note that directory /media/ramdisk must exists of the tmpfs mount will fail. Doing `mkdir -p /media/ramdisk` once before adding the above in `fstab` will be enough. – Mikko Rantalainen May 08 '20 at 08:12

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.

It woul boot up, if backup fstab and if error occurred recover it with live cd =), but i mean a RAM-Drive, not swap or anything else. I want to take a lot of space from my RAM, and make it space as drive... – litvin05 Nov 07 '10 at 20:08
