+- install puppet 
+- take the svn of admin 
+   svn co svn://svn.mageia.org/adm/ /etc/puppet/ 
+
+and then something like :
+puppetd --test --tags buildnode 
+
+( not sure about this )
+
+However, I do not recommend this, as I think what maarten want is to
+have iurt, not the whole scheduling system and upload system of the
+build system.
+ 
+> one extra question, if i use puppet to install it, it will be exactly like the

+
+Well our buildnode run on mandriva, your vm will likely be a mageia. So
+that's already a difference.
+

+
+Well, if puppet is started and start to put our ssh keys as root, yes,
+we will have access to the vm, provided that 1) we have network access
+2) time to lose on this ( neither are credible possibility ).
