There is no reason to edit mtab.... it is automatically generated... However, I do recall a few occasions when it has been corrupted and I needed to delete the entries. From the mount man page:

Code:
       The programs mount and umount maintain a list of currently mounted file systems
       in  the  file  /etc/mtab.   If  no  arguments  are given to mount, this list is
       printed.  When the proc  filesystem  is  mounted  (say  at  /proc),  the  files
       /etc/mtab  and /proc/mounts have very similar contents. The former has somewhat
       more information, such as the mount options used, but is not necessarily up-to-
       date  (cf.  the -n option below). It is possible to replace /etc/mtab by a sym-
       bolic link to /proc/mounts, but some information is lost that way, and in  par-
       ticular  working  with the loop device will be less convenient. Also, pathnames 
        containing  spaces  are  handled  correctly  by  /etc/mtab  but  not  (yet)  by
       /proc/mounts.

-n     Mount  without writing in /etc/mtab.  This is necessary for example when 
         /etc is on a read-only file system.


FILES
       /etc/fstab file system table
       /etc/mtab table of mounted file systems
       /etc/mtab~ lock file
       /etc/mtab.tmp temporary file

mount.nfs

MOUNT.NFS(8)						      System Manager's Manual						      MOUNT.NFS(8)

NAME

       mount.nfs, mount.nfs4 - mount a Network File System

SYNOPSIS

       mount.nfs remotetarget dir [-rvVwfnsh ] [-o options]

DESCRIPTION

       mount.nfs is a part of nfs(5) utilities package, which provides NFS client functionality.

       mount.nfs  is  meant to be used by the mount(8) command for mounting NFS shares. This subcommand, however, can also be used as a standalone
       command with limited functionality.

       remotetarget is a server share usually in the form of servername:/path/to/share.  dir is the directory on which the file system	is  to	be
       mounted.

       Under  Linux  2.6.32  and  later  kernel  versions, mount.nfs can mount all NFS file system versions.  Under earlier Linux kernel versions,
       mount.nfs4 must be used for mounting NFSv4 file systems while mount.nfs must be used for NFSv3 and v2.

OPTIONS

       -r     Mount file system readonly.

       -v     Be verbose.

       -V     Print version.

       -w     Mount file system read-write.

       -f     Fake mount. Don't actually call the mount system call.

       -n     Do not update /etc/mtab.	By default, an entry is created in /etc/mtab for every mounted file system. Use this option to skip making
	      an entry.

       -s     Tolerate sloppy mount options rather than fail.

       -h     Print help message.

       nfsoptions
	      Refer to nfs(5) or mount(8) manual pages.

NOTE

       For further information please refer nfs(5) and mount(8) manual pages.

FILES

       /etc/fstab	 file system table

       /etc/mtab	 table of mounted file systems
