 Ok. Then my suggestion is just replicating current status. Well... ;-)

 This doesn't appeal to my "estetic sense"... ;-7

 Ahh... beeing tired again -> too few words.

The idea was to add the "name of the copy" to the "list of files in this
package", and to do this during pre/postinstall - if that is feasible.

 Now that I read it once again, the idea doesn't seems so good anymore.
