 To activate this on a client you must add the following line to the ''systemimager master'' script of the node. It will remove the pxe config file for the node from the pxe bootserver. I personally place the line just before the ''umount'' commands. See below which command to use for which systemimager version.

 == Example how to use pxeconfig utility ==
 
-The pxeconfig command creates soft-links in the ''/tftpboot/pxelinux.cfg'' directory named as the hexadecimally encoded IP-address of the clients, and these links will point to one of the files default.*. As designed, the PXE network booting process will download the file given by the hexadecimal IP-address, and hence network installation of the node will take place. With pxeconfig you can easily create those links for the host(s)
+The pxeconfig command creates soft-links in the ''/tftpboot/pxelinux.cfg'' directory named as:
+ * hexadecimally encoded IP-address of the clients
+ * mac address with a ''01-'' prefix
 
-There are serveral ways to run pxeconfig:
- * interactively, network range
- * hostname(s)
- * host range
- * rack(x) and node(y) specification 
+The links will point to one of the files default.*. As designed, the PXE network booting process will download the file given by the hexadecimal IP-address
+or 01-<mac address>, and hence network installation of the node will take place. With pxeconfig you can easily create those links for the host(s)
 
-We will discuss the ''long'' options for pxeconfig for the ''short'' options:
+For usage and some examples
 {{{
-pxeconfig -h
+pxeconfig [-f,--filename <name>] <hosts>
 }}}
 
-if {{{-f,--filename}}} is not specified the program will display a menu where the user can choose from.

-=== hostname(s) ===
+=== hosts specifications ==
 
-the following command will make links to the ''default.node_install'' file for hosts ''gb-r1n1'' and ''gb-r1n2'':
+With ''[]'' you can specify a range. This ranges are not only limited to numbers. Some examples
+
+  * The first five nodes of rack 16
 {{{
-pxeconfig gb-r1n1 gb-r2n1 --filename default.node_install
+gb-r16n[1-5]
 }}}
 
-=== host range ===
+  * The first five nodes and node 12 and 18 of rack 16 to 20
+{{{
+gb-r[16-20]n[1-5,12,18]
+}}}
 
-We want to make links for a ''range'' of hosts, eg node1 till node100, This can be acomplished with these commands:
- * {{{ pxeconfig --basename node --host-range 1-100 --filename  default.node_install}}}
- * {{{ pxeconfig --basename node --start  1 --end 100  }}}
+  * The first five nodes de in rack 16 with padding enabled
+{{{
+gb-r[16]n[01-5]
+}}}
 
 
-Some sites have name their hosts, eg: node001 till node099. This can also be acomplished in several ways:
- * {{{ pxeconfig --basename node --equal-width --host-range 1-099 }}}
- * {{{ pxeconfig --basename node --host-range 001-099 }}}
- * {{{ pxeconfig --basename node --start 001 --end 099 }}}
-
-=== rack(x) and node(y) specification ===
-
-We want make links for hosts with a naming schema(s) like this:
+=== Example === 
+ * the following command will make links to the ''default.node_install'' file for hosts in rack 2 and host bas. Where bas is
+defined in ''pxeconfig.conf'' as host with a mac address
 {{{
- gb-r<number>n<number> 
- node-(number)-(number)
+pxeconfig gb-r2n[1-20] bas  --filename default.node_install
 }}}
-
-These examples will create links for node1, node2 and node3 in rack1, rack2 and rack3:
- * {{{ pxeconfig --basename gb- -rack r1-r3 --node n1-n3 --filename default.memtest }}}
- * {{{ pxeconfig --basename node --rack 1-3 --node 1-3 --filename default.memtest }}}
-
-When leading zeros are used, then rack and/or node names will be padded with zeros, eg:
-  * {{{ pxeconfig --basename gb- -rack r01-r02 --node n01-n02 --filename default.memtest }}}
-{{{
-will create links for hosts:
-  * gb-r01n01
-  * gb-r01n02
-  * gb-r02n01
-  * gb-r02n02
