fstab - static information about the filesystems
The file fstab contains descriptive information about the various file
systems. fstab is only read by programs, and not written; it is the
duty of the system administrator to properly create and maintain this
file. Each filesystem is described on a separate line; fields on each
line are separated by tabs or spaces. Lines starting with '#' are com-
ments. The order of records in fstab is important because fsck(8),
mount(8), and umount(8) sequentially iterate through fstab doing their
'fstab' is a static file of information that should only be changed by the 'superuser' or 'root'. If you would provide us with more information as to what you are attempting to do then we could possibly direct you.
