Hi,

we're currently evaluating a migration from Centos 5 to SL6. But I have some 
questions about repositories:

We have a local repository were our servers get their updates from. But I'm 
unsure, what I exaclty have to mirror. On the FTP there are the following 
directories:

- 6
- 6.0
- 6rolling
- 6x

Question 1: What are the differences?

Question 2: The default *.repo uses the $releasever variable, which is 
resolved to "6.0". If we plan to always have the newest (minor) version after 
every update, I think I have to replace that. Is there an other variable for 
that or do I have to hardcode it?

Question 3: Do I have to block any package that would recreate the SL repo 
files after an upgrade?


Regards,
Marc
