     Name
          rmtab - Remotely mounted file system table


     Description
          rmtab resides in directory /etc and contains a record of all
          clients  that  have  done remote mounts of file systems from
          this machine.  Whenever a remote mount is done, an entry  is
          made  in  the rmtab file of the machine serving up that file
          system.  umount removes entries, if of  a  remotely  mounted
          file  system.   umount  -a  broadcasts  to  all servers, and
          informs them that they should remove all entries from  rmtab
          created  by the sender of the broadcast message.  By placing
          a umount -a command in /etc/rc.boot,  rmtab  tables  can  be
          purged  of  entries  made  by  a  crashed  host,  which upon
          rebooting did not remount  the  same  file  systems  it  had
          before.  The table is a series of lines of the form

               hostname:directory

          This table is used  only  to  preserve  information  between
          crashes, and is read only by mountd(NADM) when it starts up.
          mountd keeps an in-core  table,  which  it  uses  to  handle
          requests    from    programs    like   showmount(NADM)   and
          shutdown(ADM).

     Notes
          Although the rmtab table is close to the truth,  it  is  not
          always 100% accurate.
