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 bytes are the null-padded name of the place where the special file is mounted; the second 32 bytes 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(1) if there are duplicated entries nor to umount(1) if a name cannot be found.
