You know, I'm sitting here trying to figure out what exactly you're trying to say, and I thought about the diference between clean metadata and clean all.

So I decided to add a little to today's burden on my local mirrors and check the difference on a day with no downloads. No difference. So, I was wrong. No extra overhead for clean all vs. clean metadata on days with no downloads. > Multiplied by all the other people who would do the same... 0 multiplied by what, a thousand? A million? (I wish.

If I have, say, 90M of updated packages, are you saying that having the old packages in my cache somehow saves bandwidth? Has yum been upgraded to run in diff mode, then? That would be good news, indeed, although I haven't seen such evidence in the download sizes. Now, if I had more than one machine in the house running the same version of Fedora, I would definitely be looking at putting up alocal proxying miror of some sort. I see from other comments that some people seem to be making use of their cache as manual mirrors, ... >> I have had my cache clogged on occasion, preventing security updates >> from downloading, which is why I tend to use the clean all option. > > Though, rarely does the fault actually require the brute force "all" > option. Well, anyway, since you insist there's an advantage, I'll dig around and see what it might be. Right now, I'm afraid you're either not making sense, or you're assuming I have more than one machine running the same distribution on the inside LAN. Assuming I'm running in a hosted VM, maybe?
