| UUID UUID “Universally Unique Identifier” is used in the field of the software, translate in Italian language is not other that “Universal Only Identificatore”. Draft of a product realized from the Open Software Foundation (OSF) as it leave of system DCE. A UUID is essentially a 16-byte number (128-bit). In the relative esadecimale shape a UUID can be similar this: 0aa86c61-0df9-4f1a-8c0b-34abbee6b769 Although the UUID does not guarantee a effective oneness, the possible number of combinations so is elevated to avoid one possible coincidence between two codes. The possible number of combination of the UUID is 2128 = 25616 = approximately 3.4 x 1038. That means that 1 trillion of UUID must be generates every nanosecond to you so that between 10 billions of years the UUID number is get exaustedded and to return to regenerate the same UUID.

Introduction
The configuration file /etc/fstab contain the necessary information to mount of the disk. This file comes read at the start of the system and can be modified only by [:SudoRoot:root] user.
= Content of the file = It is possible to visualize this file with the followed commands:
cat /etc/fstab
The result of the previous commando will be similar to following:
# /etc/fstab: static file system information. # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc defaults 0 0 # /dev/hda1 UUID=12102C02102CEB83 /media/windows ntfs silent,umask=0,locale=it_IT.utf8 0 0 # /dev/hda2 UUID=cee15eca-5b2e-48ad-9735-eae5ac14bc90 none swap sw 0 0 # /dev/hda3 UUID=98E0-6D24 /media/dati vfat defaults,utf8,umask=007,uid=0,gid=46,auto,rw,nouser 0 0 # /dev/hda4 UUID=0aa86c61-0df9-4f1a-8b0b-34abbee6b769 / ext3 nouser,defaults,errors=remount-ro,atime,auto,rw,dev,exec,suid 0 0 /dev/hdc /media/cdrom0 udf,iso9660 user,atime,noauto,rw,dev,exec,suid 0 0
