"yum update" for RHEL/CentOS boxes

[legal90]

While Ubuntu boxes are building, all packages are automatically updated via the update.sh script:

What do you think about doing the similar for RHEL/CentOS boxes? Is there any strong concerns against doing yum update?

It is related to GH-406, since yum update can cause a distro minor version to be updated.

So that particular script doesn't actually ""upgrade" the packages it just runs "update" which just updates the package list itself. For ubuntu the preseed.cfg actually does a 'full-upgrade' during the install process.

That said I don't see anything in the kickstart config for RHEL platforms that is doing similar. I'm certainly open to discussing adding this level of functionality.

Related to #406 (comment) - we don't want to update/upgrade the boxes to a new minor release as this is diverges with user expectations and also allows for testing the box from an 'vanilla' state for testing upgrades.

@cheeseplus Thanks for the explanation! I agree that we have to keep 'vanilla' state of the distribution.
I'll close this issue.
