+If a B<workdir> is spezified and the UID is 0, rrdtool will do a
+chroot to the workdir. If the UID is not 0, rrdtool only changes the
+current directory to B<workdir>.

+=head2 RRD Server
+
+If you want to create a RRD-Server, you must choose a TCP/IP Service
+number and add them to I</etc/services> like this:
+
+ rrdsrv 13900/tcp # rrd server
+
+Attention: the tcp port 13900 isn't official registered for rrdsrv. You
+can use any unused port in your services, but the server an the client
+system must use the same port of curse.
+After this you can add the rrdtool as meta-server to I</etc/inetd.conf>
+for example:
+
+ rrdsrv stream tcp nowait root /opt/rrd/bin/rrdtool rrdtool - /var/rrd
+
+Don't forget to create the database directory /var/rrd and reinitialize
+your inetd.
+If all was correct, you can access the server with perl sockets, tools
+like netcat or a quickhack test 'telnet localhost rrdsrv'.
