create ram disk
mount ramdisk after bootup:
mount -t tmpfs -o size=1024m ramdisk /idoru/ram
‘ramdisk’ is the device name (arbitrary)

ramdisk /idoru/ram tmpfs defaults,size=1G,x-gvfs-show 0 0
tmpfs vs ramfs
- tmpfs is the successor of ramfs
- ramfs can have no upper limit for filesystem size, thus data can eat up all your ram
- tmpfs has a fixed size
- tmpfs can swap pages to swap space (you might not want that to happen)
