This week’s TechMail is Save time on downloads with delta RPMs in Fedora 11 which discusses the delta RPM feature in Fedora, how to set it up and use it, and why you would want to. Delta RPMs don’t make sense for everyone, but they will for quite a few people (i.e. low bandwidth situations with decent processor speeds as opposed to high bandwidth and possibly lower processor speeds). Regardless, delta RPMs are quite cool and I know at Mandriva we had wanted to do this years ago and it just never panned out, so it’s cool to see it working now.
