Este é um meta-arquivo fstab, bem comentado e com descrições sobre o preenchimento de cada coluna. Este arquivo traz a configuração padrão de montagem do GNU/Linux (diretório raíz, proc e swap) e ainda exemplo com partição Windows, Disquetes, DVD-ROM, além da montagem de diversos diretórios da árvore de diretórios em partições separadas. Os comentários estão em inglês, mas para aqueles que não entenderem esta linguagem, sugiro acessar o endereço http://www.linuxbsd.com.br/portal/index.php?q=node/66 para esclarecimentos sobre o arquivo.

# DESCRIPTION ..: Saves static information about the filesystems.
# INSTRUCTIONS .: Copy this file to the /etc directory and give it 644
# permission.

# FIELDS' EXPLANATION
# Type "$ man 5 fstab" for more details about these fields.
# Type "$ man 8 mount" for more details about mount options and supported
# filesystems.
#===============================================================================
# 1. The first field, (fs_spec), describes the block special device or remote
# filesystem to be mounted.
# Ex.: /dev/sda1
# 2. The second field, (fs_file), describes the mount point for the filesystem.
# For swap partitions, this field should be specified as `none'. If the name
# of the mount point contains spaces these can be escaped as `{CONTEUDO}40'.
# Ex.: /mnt/cdrom
# 3. The third field, (fs_vfstype), describes the type of the filesystem. Linux
# supports lots of filesystem types, such as adfs, affs, autofs, coda,
# coherent, cramfs, devpts, efs, ext2, ext3, hfs, hpfs, iso9660, jfs, minix,
# msdos, ncpfs, nfs, ntfs, proc, qnx4, reiserfs, romfs, smbfs, sysv, tmpfs,
# udf, ufs, umsdos, vfat, xenix, xfs, and possibly others. For more details,
# see mount(8). For the filesystems currently supported by the running
# kernel, see /proc/filesystems. An entry swap denotes a file or partition to
# be used for swapping, cf. swapon(8). An entry ignore causes the line to be
# ignored. This is useful to show disk partitions which are currently unused.
# Ex.: auto
# 4. The fourth field, (fs_mntops), describes the mount options associated with
# the filesystem.
# Ex.: defaults
# 5. The fifth field, (fs_freq), is used for these filesystems by the dump(8)
# command to determine which filesystems need to be dumped. If the fifth
# field is not present, a value of zero is returned and dump will assume that
# the filesystem does not need to be dumped.
# Ex.: 0
# 6. The sixth field, (fs_passno), is used by the fsck(8) program to determine
# the order in which filesystem checks are done at reboot time. The root
# filesystem should be specified with a fs_passno of 1, and other filesystems
# should have a fs_passno of 2. Filesystems within a drive will be checked
# sequentially, but filesystems on different drives will be checked at the
# same time to utilize parallelism available in the hardware. If the sixth
# field is not present or zero, a value of zero is returned and fsck will
# assume that the filesystem does not need to be checked.
# Ex.: 2
