NOTE: There is NO mechanism to pick only partial upgrades of packages to CentOS-6.10. All packages and updates to the 6.10 tree are built against the 6.10 tree and may not work correctly with older 6.x packages. If you want some packages in 6.10, please upgrade all packages. You will have issues if you perform only partial updates.
The mirrorlist script has been temporary replaced to avoid unwanted updates.
We will switch back to the original one as soon as the update has been tested.
