Re: Yum, Proxy Cache Safety, Storage Backend

Getting a bit off the original topic here, but the "other" thing I've
always wished yum could do is "repeatable" updates.  That is, the
ability to update one machine, test some things, then update another and get only the same set of changes even if some newer packages had been
subsequently added to the repos.

To me, that isn't functionality for the client, it is functionality for the server / cache. It is a feature of WSUS - the ability to approve updates and only allow clients to "see" the approved ones and not any other.

Right now, there isn't a lot of intelligence built into the server end ( MirrorManager excepted ) of the update process. The repositories serve static files, that's it. Fedora can't ask any more from mirrors. If in your environment you want to control how clients get updated, then it makes sense to me that centralized control from the server side and keeping the client side "dumb" is better. You only have to distribute the repo configuration to use the controlled repo once, instead of distributing specific update lists continually.

That control is one of the reasons why as an admin I am interested in InstantMirror and this discussion.
