So i digged a little bit for this :

- conditional requirement -> this can be done in puppet as well ( using
conditionals ).
- conflict =>  we can use " ensure => absent" to make sure a package is
not there
- virtual packages. 
Indeed, this is a weak point of puppet, we need to take ( for example )
architecture and version in account. Yet, i think we can solve it ( even
if this is not as elegant as letting ) without touching puppet, or maybe
by patching puppet to be more virtual-name friendly in the future. 
- etc, I didn't found, but I guess we can add
  - ability to add a requires a Provides, which would indeed be the same
as virtual packages. 


In the mean time, I have also took a look at the rpm pulled by
task-bs-cluster-chroot :

task-bs-cluster-chroot 
   task-bs-common  
      basesystem        
      urpmi             
      cfengine-cfagent  
      openssh-server    
      sshd-monitor      
      openldap-clients  
      nss_ldap         
      pam_ldap         
      nscd             
      sudo             
      zsh              
      nail             
      ntp              
      smartmontools    
      perl-Image-Size  
   autofs              
   nfs-utils-clients   
   mdv-youri-submit    
   mdv-distrib-tools   
   mkcd                
   perl-File-NCopy     
   perl-Filesys-Df     
   perl-MIME-tools     
   perl-RPM4           
   rpmmon              
   repsys              
   mdvsys              
   icecream            
   postfix             
   db42-utils          
   db4-utils >= 4.6    
   rpmlint             
   rpmlint-mandriva-policy


So here is some sorting :
urpmi, basesystem, cfengine-cfagent, mdvsys, rpmlint,
rpmlint-mandriva-policy, zsh are not needed on a pure buildhost. Well,
urpmi and basesystem are already here in fact. And I hope that we
finally got ride of the zsh script of chmouel :)

openssh-server, nss_ldap, pam_ldap, nscd, sudo, sshd-monitor, ntp, nail,
postfix, openldap-clients are already handled by puppet ( ssh is
monitored by puppet with Service )

smartmontools and icecream should be converted to puppet module. 

i am not sure that rpmmon work or is really needed. I remeber having
seems it being used at iurt.

autofs, nfs-utils-clients. I do not think autofs will be useful, and for
nfs-utils-client, we can use the mount type, and indeed add a requires
on it, since it seems iurt need nfs.

This let us with the following packages :
   
   perl-File-NCopy 
   perl-Filesys-Df
   perl-MIME-tools
   perl-RPM4
   perl-Image-Size     

I assume these are needed for some script. However, since there was lots
of cruft, I would be in favor of : 
- removing them, see what break, add those that are required 


   db42-utils
   db4-utils >= 4.6
I also assume this was needed by some iurt hack, that blino removed
( not sure ). Again, maybe we can remove this ?

   mdv-youri-submit    
   mkcd                
   repsys

I am doubtful they are used on a pure buildhost. So maybe we can remove
them ? If they are needed because they provides some perl modules, they
will be pulled by the packages anyway.

   mdv-distrib-tools  
contain a perl module and a executable. I do not exactly what it does,
but I am pretty sure it is used on the main mirror, not on buildhost.
So we could likely remove it too. 


So, while I do not intend to remove them right now ( at least, not while
blino is still setting everything ), does people see something wrong in
the list ?

Aka, stop requiring everything, convert icecream, smartmontools and
nfs-utils to proper modules.
