112      Tmpfs is a file system which keeps all files in virtual memory.
113
114      Everything in tmpfs is temporary in the sense that no files will be
115      created on your hard drive. The files live in memory and swap
116      space. If you unmount a tmpfs instance, everything stored therein is
117      lost.
