It would help Maarten a lot :-)

one extra question, if i use puppet to install it, it will be exactly like the 
current buildnode now?

but is puppet then installed on it? because i don't want to give people the 
impression that if they install this vm, that the mageia sysadmins would have 
full control over their vm...

or am i thinking totally the wrong way?

furthermore, i'm thinking on this:
 - how long does it take to install and configure puppet and rather configure 
the puppet classes for the VM. in relation to the actual install?

i mean, if i can install this VM by just one urpmi line with --urpmi-root 
option, it seems also overkill to have puppet.

well, i guess this just proves how little i know of puppet. :-(
