Hi,
I've installed dozens of computers with autoyast1 and SuSE 7.3
in the last years. Now I need to switch to SuSE 9.0 and try
to learn the new autoyast2 interface.
However, even after reading the complete html docu for 9.0
and browsing the mailing list archives, I still don't unterstand
two things:
1) Is there any way to define IP ranges in rules?
  In autoyast1 I used to have lines like
CLASS   141.84.1.210-240        k_smp
in the main info file and info.k_smp would then contain
  a definition for using the k_smp kernel.
In the rules.xml, I only see the hostaddress attribute
  which must match exactly. I tried a range there, but
  it did not work.
How can I apply a rule to a set/range of ips without
  specifying each ip?
range is not supported for ips, but thats a good idea and i will try to 
add it for the upcoming release.

To make that happen with 9.0 however, you can always use you own script 
in the rules which you can match. For example I use this rule to match 
the boardinfo of my old thinkpad (btw, in 9.1 rules matching diferent 
smbios data will be be builtin, so you wont need the script)

     <rule>
         <custom1>
             <script>
<![CDATA[
#!/bin/sh
board=$(hwinfo --bios | grep -A 4 "Board Info" | grep Product | cut 
-d'"' -f 2 | sed -e "s/[<|>]//g" )
echo -n $board
]]>
             </script>
             <match>2628JXU</match>
             <match_type>exact</match_type>
         </custom1>
        <result>
             <profile>thinkpad.xml</profile>
             <continue config:type="boolean">false</continue>
         </result>
     </rule>

So you have to write a script that will output the latest segment of an 
IP and do a range checking, i,e, on 210-240.

so it will result in something like that(not tested):

     <rule>
         <custom1>
             <script>
<![CDATA[
#!/bin/sh
ip=$(/sbin/ifconfig eth0  | sed -n "s/\(inet\ addr:\)\([0-9.]*\).*/\2/p" 
| cut -d'.' -f 4)
echo -n $ip
]]>
             </script>
             <match>210-240</match>
             <match_type>range</match_type>
         </custom1>
        <result>
             <profile>thinkpad.xml</profile>
             <continue config:type="boolean">false</continue>
         </result>
     </rule>

Of course you can add other rules such as these to match the subnet and 
the network, etc.
...
2) Do I really have to write all the scripts inside
  a profile? Is itnot possible to just call an external
  script file?
Well, you can call an external script from the script themselves, 
however, you have to make the scripts available to the system somehow 
and the easiest solution is to include the scripts into the control file.

Thanks a lot for any help (especially for the first question, 
the second is not really that important..)
