Hi,

here's sth. which didn't work in some earlier versions (don't remember when
I last tried it) but is working at least in 10.1 alpha4. I can now use
this rule in rules.xml to chose a profile for each host based on its
name.
This works only if the host gets its name via dhcp, so this is sth.
especially nice for pxe-based installations. I provide this as example
for other people and hope that someone can make use of it :-) This
is a solution for the non-working <hostname> matching, because the
<hostname> tag contains the IP and not the hostname, even when
using pxe/dhcp.


     <rule>
       <custom1>
	<script>
<![CDATA[
#!/bin/sh
. /var/lib/dhcpcd/dhcpcd-eth0.info
echo -n $HOSTNAME
]]>
         </script>
	<match>*</match>
	<match_type>exact</match_type>
       </custom1>
       <result>
	<profile>profiles/part_(a)custom1@.xml</profile>
	<continue config:type="boolean">true</continue>
       </result>
     </rule>


I use this to store partition information per host in a file
part_<hostname>.xml in the profile subdir. No need to change
the rules.xml anymore, just create the profile with the partition
information. In these profiles, I always keep partitions, formatting
only / and /var. In case I really really want to destroy and recreate
partitions for a specific host, I add another rule afterwards, e.g.

     <rule>
       <custom1>
	<script>
<![CDATA[
#!/bin/sh
. /var/lib/dhcpcd/dhcpcd-eth0.info
echo -n $HOSTNAME
]]>
         </script>
	<match>riemann</match>
	<match_type>exact</match_type>
       </custom1>
       <result>
	<profile>profiles/part_riemann_createnew.xml</profile>
	<continue config:type="boolean">true</continue>
       </result>
     </rule>


or, IP-based:

     <rule>
        <hostaddress>
             <match>141.x.x.x</match>
             <match_type>exact</match_type>
        </hostaddress>
        <result>
             <profile>profiles/part_riemann_keep.xml</profile>
             <continue config:type="boolean">true</continue>
         </result>
     </rule>

to override the common selection.

Have fun!
cu,
Frank
