Hello, I'm running Fedora 12, and since I don't intend to upgrade, I thought I should make a copy of the yum repositories, just so I will be able to install whatever I'll need easily even in the longer term future. All examples I've seen talk about saving internet bandwidth, not endurance

Thanks, Nadav. Even though this didn't put me off 100%, your remark is valuable indeed. Since my choice of distribution and unwillingness to upgrade becomes an issue all the time, I'll put it short: I prefer to stick to a certain distro and solve its problem over upgrading all the time
