.TH UNFSD_EXPORTS 5 "11 April 1988"
.SH NAME
unfsd_exports \- NFS file systems being exported by user-level NFS server
.SH SYNOPSIS
.B /etc/unfsd_exports
.SH DESCRIPTION
.IX  "NFS exported file systems"  ""  "NFS exported file systems \(em \fLexports\fP"
The file
.I /etc/unfsd_exports
describes the file systems which are being exported to 
nfs clients.
It is processed by the
.I user-level NFS
daemon
.IR unfsd (8C)
when the daemon is started.
.PP
The file format is similar to that of the SunOS
.I exports
file.
The file is organized by lines.
A # introduces a comment to the end of the line,
a \e preceding a new line disables the line break making the entry of
long input lines more convenient.
Each line consists of a mount point
and list of machine names
allowed to remote mount the server's file hierarchy at that mount point.
A machine name is optionally followed by a list of mount parameters
enclosed in parentheses.
These are the parameters that are currently recognized.
