 114           Tmpfs is a file system which keeps all files in virtual memory.
 115
 116           Everything in tmpfs is temporary in the sense that no files will be
 117           created on your hard drive. The files live in memory and swap
 118           space. If you unmount a tmpfs instance, everything stored therein is
 119           lost.
