mtab resides in the /etc directory, and contains a table of filesystems currently mounted by the mount.8 command. umount removes entries from this file.
The file contains a line of information for each mounted filesystem, structurally identical to the contents of /etc/fstab, described in fstab.5 There are a number of lines of the form:
fsname dir type opts freq passno
/dev/xy0a / 4.2 rw,noquota 1 2
The file is accessed by programs using getmntent.3 and by the system administrator using a text editor.
