MOUNT(8)                GENIX Programmer's Manual                MOUNT(8)



      NAME
           mount, umount - mount and dismount file system

      SYNOPSIS
           /etc/mount [ special name [ -r ] ]

           /etc/mount -a

           /etc/umount special

           /etc/umount -a

      DESCRIPTION
           Mount announces to the  system  that  a  removable  file  system  is
           present  on the device special. The file name must exist already; it
           must be a directory (unless the root of the mounted file  system  is
           not  a  directory).   It becomes the name of the newly mounted root.
           The optional argument -r indicates that the file  system  is  to  be
           mounted read-only.

           Umount announces to the system that the removable file system previ-
           ously mounted on device special is to be removed.

           If the -a option is present for either mount or umount, all  of  the
           file  systems described in /etc/fstab are attempted to be mounted or
           unmounted.   In  this  case,  special  and  name  are   taken   from
           /etc/fstab.  The special file name from /etc/fstab is the block spe-
           cial name.

           These commands maintain a table of mounted devices in /etc/mtab.  If
           invoked without an argument, mount prints the table.

           Physically write-protected and magnetic tape file  systems  must  be
           mounted  read-only  or  errors  will  occur  when  access  times are
           updated, whether or not any explicit write is attempted.

      FILES
           /etc/mtab mount table
           /etc/fstab     file system table

      BUGS
           Mounting file systems full of garbage will crash the system.
           Mounting a root directory on a non-directory makes  some  apparently
           good pathnames invalid.
