NAME
       mtab - mounted file system table

DESCRIPTION
       Mtab resides in directory /etc and contains a table of devices mounted by the mount command.  Umount removes entries.

       Each  entry  is	64 bytes long; the first 32 are the null-padded name of the place where the special file is mounted; the second 32 are the
       null-padded name of the special file.  The special file has all its directories stripped away; that is, everything through the last `/'	is
       thrown away.

       This  table  is present only so people can look at it.  It does not matter to mount if there are duplicated entries nor to umount if a name
       cannot be found.

FILES
