From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5) Gecko/20030925 Description of problem: Yum slowly d/ls headers for the base upon first invocation of "yum update" without any arguments. This is a waste of time, because the installation process could have installed those headers. It would be more efficient to just ship a yum-headers.rpm in the distro so it didn't have to download all these headers from the server on each machine, and install that rpm by default. Version-Release number of selected component (if applicable): 2.0.4-2 How reproducible: Always Steps to Reproduce: 1. yum update Actual Results: It tries to get all the headers in /var/cache/yum/base/ as well as in /var/cache/yum/updates-released/ Expected Results: The headers in /var/cache/yum/base/ should have been preinstalled Additional info:
In principle, yum's cache could have been primed by preparing a package with all the correct headers, yes. In reality, packages tend to change too rapidly to keep a yum-headers package up-to-date. Furthermore, it just changes the problem of cache priming from slow on yum out-of-box to slow downloading of the yum-headers package before running yum for no overall win. Sooner or later the user needs to populate yum's cache with headers. The current scheme is more flexible but cruder. Better solutions are in the the works using xml instead of headers. WONTFIX until then.
