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 .Pa /etc/exports , the entire file system in which the swapfiles resides will have to be exported with the .Fl alldirs flag. .It Fl D The .Fl D option will cause mountd to log lots of information about its inner-workings via .Xr syslog 3 using the LOG_DAEMON facility and the LOG_DEBUG priority. .It Fl d The .Fl d option will cause mountd to not daemonize itself and it will log lots of information about its inner-workings to stderr instead of .Xr syslog 3 . .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 .Xr nfssvc 2 system call. After changing the list of exports (either directly or indirectly via a change in netgroup membership), a hangup signal should be sent to the mountd daemon to get it to reload the export information: .Pp .Dl "kill \-s HUP `cat /var/run/mountd.pid` .Pp Any errors encountered while processing the export entries will be logged via .Xr syslog 3 . .Sh FILES .Bl -tag -width /var/run/mountd.pid -compact .It Pa /etc/exports the list of exported filesystems .It Pa /var/run/mountd.pid the pid of the currently running mountd .It Pa /var/run/mountdtab the current list of outstanding mounts served .It Pa /var/run/mountdexptab information about exported file systems and directories (UUIDs, handles, ...) .El .Sh SEE ALSO .Xr nfsstat 1 , .Xr exports 5 , .Xr nfsd 8 , .Xr portmap 8 , .Xr showmount 8 .Sh HISTORY The .Nm mountd utility first appeared in 4.4BSD.
