/etc/fstab entry description

The following is an example of an fstab file on a typical Linux system:

# device name   mount point     fs-type      options                 dump-freq pass-num
LABEL=/         /               ext3         defaults                1 1
/dev/hda6       swap            swap         defaults                0 0
none            /dev/pts        devpts       gid=5,mode=620          0 0
none            /proc           proc         defaults                0 0
none            /dev/shm        tmpfs        defaults                0 0

/dev/fd0        /mount/floppy   auto         noauto,owner,kudzu      0 0

# NTFS Windows XP partition
/dev/hda1       /mnt/WinXP      ntfs-3g      quiet,defaults,locale=en_US.utf8,umask=0    0 0

# Partition shared by Windows and Linux
/dev/hda7       /mnt/shared     vfat         umask=000              0 0

# mounting tmpfs
tmpfs           /mnt/tmpfschk   tmpfs        size=100m              0 0

# mounting cifs
//pingu/ashare  /store/pingu    cifs         credentials=/root/smbpass.txt 0 0

#mounting NFS
pingu:/store    /store          nfs          rw                     0 0

The columns are as follows:

1. The device name or other means of locating the partition or data source.
2. The mount point, where the data is to be attached to the filesystem.
3. The filesystem type, or the algorithm used to interpret the filesystem.
4. Options, including if the filesystem should be mounted at boot. (kudzu is an option specific to Red Hat and Fedora Core.)
5. dump-freq adjusts the archiving schedule for the partition (used by dump).
6. pass-num indicates the order in which the fsck utility will scan the partitions for errors when the computer powers on. 0 = none, 1 = first, 2 = next (and all others in order)
