exportfs(1M)

NAME
     exportfs - export and unexport directories to NFS clients

SYNOPSIS
     /usr/etc/exportfs [ -aiuv ] [ -o options ] [ directory ]

DESCRIPTION
     exportfs makes a local directory (or file) available for mounting over
     the network by NFS clients.  It is normally invoked at boot time by the
     /etc/init.d/network script, and uses information contained in the
     /etc/exports file to export a directory (which must be specified as a
     full pathname).  The superuser can run exportfs at any time to alter the
     list or characteristics of exported directories.  Directories that are
     currently exported  are listed in the file /etc/xtab.

     With no options or arguments, exportfs prints out the list of directories
     currently exported.

OPTIONS
     -a   All.  Export all directories listed in /etc/exports, or if -u is
          specified, unexport all of the currently exported directories.

     -v   Verbose.  Print each directory as it is exported or unexported.

     -u   Unexport the indicated directories.

     -i   Ignore the options in /etc/exports.  Normally, exportfs consults
          /etc/exports for the options associated with the exported directory.

     -o options
          Specify a comma-separated list of optional characteristics for the
          directory being exported.  options are described in exports(4).

FILES
     /etc/exports      static export information
     /etc/xtab         current state of exported directories
     /etc/netgroup

SEE ALSO
     exports(4), netgroup(4), showmount(1M).

WARNINGS
     You cannot export a directory that is either a parent- or a sub-directory
     of one that is currently exported and within the same filesystem.  It
     would be illegal, for example, to export both /usr and /usr/local if both
     directories resided in the same disk partition.

     Extremely long export lists (hundreds of hosts or netgroups for a single
     exported directory) may cause mount requests for that exported directory
     to time out.
