Thanks for bringing up these points. You are undoubtedly correct that there's an unknown cost associated with these changes, but hopefully the cost will become a little clearer once we have a POC. > (Also on this topic, I should note that the OSTree data format cleanly > fixes a lot of the issues being discussed here; it has deltas, and also > doesn't make the mistake of checksumming compressed data, > when performing updates only changed files are rewritten, not to mention > a whole transactional update system, etc.) Yep. I've experimented with OSTree and love the concepts behind it. I don't think we're quite ready to ditch the classic rpm systems yet, though.
