+.Sh NAME
+.Nm mountd
+.Nd service remote
+.Tn NFS
+mount requests
+.Sh SYNOPSIS
+.Nm /sbin/mountd
+.Op Fl nr
+.Op Ar exportsfile
+.Sh DESCRIPTION
+.Xr Mountd
+is the server for
+.Tn NFS
+mount requests from other client machines.
+.Xr Mountd
+listens for service requests at the port indicated in the
+.Tn NFS
+server specification; see
+.%T "Network File System Protocol Specification" ,
+RFC1094, Appendix A and
+.%T "NFS: Network File System Version 3 Protocol Specification" ,
+Appendix I.
+.Pp
+Options and operands available for
+.Nm mountd :
+.Bl -tag -width Ds
+.It Fl n
+The
+.Fl n
+option allows non-root mount requests to be served.
+This should only be specified if there are clients such as PC's,
+that require it.
+.It Fl r
+The
+.Fl r
+option allows mount RPCs requests for regular files to be served.
+Although this seems to violate the mount protocol specification, some diskless
+workstations do mount requests for their swapfiles and expect them to be
+regular files. Since a regular file cannot be specified in /etc/exports, the
+entire file system that the swapfiles reside in will have to be exported with
+the ``-alldirs'' flag.
+.It Ar exportsfile
+The
+.Ar exportsfile
+argument specifies an alternate location
+for the exports file.
+.El
+.Pp
+When mountd is started,
+it loads the export host addresses and options into the kernel
+using the mount(2) system call.
+After changing the exports file,
+a hangup signal should be sent to the mountd daemon
+to get it to reload the export information.
+After sending the SIGHUP
+(kill -HUP `cat /var/run/mountd.pid`),
+check the syslog output to see if mountd logged any parsing
+errors in the exports file.
+.Pp
+If
+.Nm mountd
+detects that the running kernel does not include
+.Tn NFS
+support, it will attempt to load a loadable kernel module containing
+.Tn NFS
+code, using
+.Xr modload 8
+by way of
+.Xr vfsload 3 .
+If this fails, or no
+.Tn NFS
+LKM was available,
+.Nm mountd
+exits with an error.
+.Sh FILES
