NAME
       exports - define remote mount points for NFS mount requests

SYNOPSIS
       /etc/exports

DESCRIPTION
       Exports	specifies  remote  mount points for the NFS mount protocol per
       the NFS server specification; see ``Network File System Protocol Speci‐
       fication, RFC1094''.

       Each  line  in  the  file  specifies one remote mount point.  The first
       field is the mount point directory path followed optionally  by	export
       options	and  specific  hosts separated by white space.	Only the first
       entry for a given local file system may	specify	 the  export  options,
       since  these  are handled on a per local file system basis.  If no spe‐
       cific hosts are specified, the mount point is exported to all hosts.

       The export options are as follows: -root=<uid>  specifies  how  to  map
       root's  uid  (default  -2).   The option -r is synonyms for -root in an
       effort to be backward compatible with older export file formats.

       -ro specifies  that  the	 file  system  should  be  exported  Read-only
       (default	 Read/Write).	The option -o is synonyms for -ro in an effort
       to be backward compatible with older export file formats.

       For example:
	      /usr -root=0 rickers snowhite.cis.uoguelph.ca
	      /usr/local 131.104.48.16
	      /u -root=5
	      /u2 -ro

       given that /usr, /u and /u2 are local file system mount points,	speci‐
       fies the following:
	      /usr  is	exported to hosts rickers and snowhite.cis.uoguelph.ca
	      with root mapped to root.
	      /usr/local is exported to host 131.104.48.16 with root mapped to
	      root.
	      /u is exported to all hosts with root mapped to uid 5.
	      /u2 is exported to all hosts Read-only with root mapped to -2.

       Note  that /usr/local -root=5 would have been incorrect, since /usr and
       /usr/local reside in the same local file system.

FILES

BUGS
       It would be nice if the export options were not	tied  to  local	 mount
       points.
