Hi, OLPC has a custom OS update system based on rsync of differences of 1 filesystem image to the next. To make this as quick and efficient as possible, we have an interest in reducing needless delta between the old version and the 2. Currently, every time we do a new build, there are huge differences in the yumdb, even if the set of installed packages didn't really change between the 2 builds. This is because the from_repo_revision and from_repo_timestamp files change under each db entry. We'd save time if we could avoid changes in those files. So, my question is: what is the utility of those files? I see that they get displayed with the "yumdb info" command. Anything else? If I were to set the value 0 in all of those from_repo_revision/from_repo_timestamp files, meaning that they wouldn't change from build-to-build, would there be any obvious side effects?
