[Gllug] Repository expansion approach

Can I 'seed' my 5.5 repo with the previous version's files and perhaps 
save some rsync time/traffic; or is this is bad idea?

A bit of 'Friday finking' by a non-SysAdmin:

I have local repositories for CentOS 5.3 and 5.4. rsync is utilised to 
pull down a copy from my closest CentOS 'mirror' site. Thereafter this 
is fed into my LAN's Cobbler server. All local installs and updates run 
from there; saving multiple update downloads, my systems don't have to 
run yum-updatesd, ...

Now that CentOS 5.5 has been released, the repo/Cobbler server needs to 
be expanded. Given that some files will not have changed between 5.4 and 
5.5, if I were to rename my 5.4 directories to 5.5 (and update the rsync 
command accordingly) might this save me some download traffic? (before 
feeding the combination into Cobbler as "5.5")

Conversely, would the older version be a faulty foundation for the new 

Anyone thought this one through, been-there-done-that?
