Hi All,

Whilst I am sure this must have been discussed before I cannot find any 
information on it.

I am looking at creating a local(private) mirror for some of our 
servers, but it is not clear which repos are needed and indeed what they do.

Looking at version 6 specifically we have

6 (i386/x86_64/external_products sym linked to 6x)
6x (i386/x86_64 sym linked to 6.5)
6.5
6.4
6.3
6.2
6.1
6.0
6rolling

I assume that 6 and 6x are symlinked for backwards compatability, is 
this correct? and that 6x always links to the latest minor release?
I see that 6x is a repo in 6.4 and 6.5 installs, but does not exist in 
the <6.3 repos
Also is 6rolling essentially testing?

Since I am a little short on disk space for hosting this, do I need all 
minor releases?  Or just the ones for the minor releases we have 
running?  If I have a 6.2 OS, can I just add the 6x repo and update 
making it a 6.5?  Do I have to do anything else?

Regards
Robin.
