So far I have imported all the files in the "repodata" directory, but yum only seems to use primary.xml.gz and repomd.xml. Do I need to have the other files (filelists.xml.gz, other.xml.gz)? They are much bigger than the two that are getting used, so if I don't need them, it will speed up the updating process a lot. > 2. Persuade yum to give me a list of packages (that I need to download > in order to execute a package install or update) and capture that > list in a format that I can feed into rsync (at work). I don't know if I succeeded or failed at this one. I issue a "yum resolvedep xorg-x11" command, all I get back is: Searching Packages for Dependency: Setting up repositories Reading repository metadata in from local files 0:xorg-x11-6.8.2-1.EL.13.25.1.x86_64 I am fairly certain that I have to install the libraries when upgrading a big package like X11, so the response is a bit baffling to me. when I running "yum deplist xorg-x11" I get pages and pages of dependencies without any indication of which packages I already have on my computer, and which I don't. I ran "yum deplist firefox", which I just installed, and yum gave me the pages of dependencies, but the packages are already there. What I need is a list of all the packages I need to download to install that package, so I can go to work, download them all, bring them home, transfer them to the computer, and turn yum loose to do the install. > 3. Have a way to separate package list into three categories: > a. Packages already in correct version my local repository. > b. Packages needing an update in my local repo. > c.

I only wanted two packages today (Firefox 1.5 and Thunderbird 1.5), so I just did the download "by hand". > 6. Bring USB drive home and dump contents into local repo. Did it "by hand" > 7. Run yum to do the updates.
