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

 129           Extended attributes are name:value pairs associated with inodes by
