etch --> lenny dpkg selections

[Ivan Savov <ivan@cnd.mcgill.ca>]

Hello,


I have been using dpkg --get-selections and --set-selections to  
replicate the client machines at work. It works super well.

Yesterday I added a new machine (lenny 5.0) and I would like to set  
the same packages
as I have system wide, however the other machines I have are still  
running etch.

I see that the output of --get-selections contains the package version  
information so I am
wondering if that is going to be a problem.

Is there a way to specify which packages to install but not insist on  
the version?
What if I simply delete the column with package version?
If you could point me to some info about the --get-selections --set- 
selections data format, maybe I can write a script that automatically  
changes/deletes the version.


Yours,
  Ivan


PS: I am also interested in replicating package configurations  
(debconf-get-selections and DPkg::Post-Install-Pkgs) but I need to do  
more research on that one before I start buging you with questions...
